Page 6: Important Note
Important Note Using modern RAID Systems significantly increases data security and availability. Un- der no circumstances does it relieve you from a careful and daily backup on tape or a similar backup media. This is the only method to protect your valuable data against total loss (e.g., through fire or theft), accidental deletion, or any other destroying im- pacts.

Page 22: General Information
A.4 General Information The ICP Controller should be installed by an authorized ICP vortex distributor. Precondition for the safe installation is an anti-static work place (earthed mat on the table with wrist bands connected to an earth). ICP vortex does not take any responsibility for damage aris- ing out of improper installation.

troller. Thus, the host is significantly off-loaded. In addition, this hardware-implemented solution guarantees the highest achievable security. The controller-BIOS provides a com- plete PCI compatible INT13 interface and expands the respective functions of the system BIOS. It also ensures that operating systems using the INT13 (i.e. MS-DOS) can be booted directly from a SCSI device / RAID Array Drive connected to the ICP Controller.

Page 39: Scsi - Basics
B.4 SCSI - Basics Whoever has been involved with the subject of SCSI will have noticed that the "Small Com- puter System Interface" is an extremely interesting technology, which has become widely accepted in comparison to other interface models and has constantly adapted to the needs of customers.
Page 40: Scsi Cables
160MB/sec synchronous data transfer rate Up to 12 Meters cable length It is very important for you to observe the information and notes given in this section of the User’s Manual because it helps to ensure that the SCSI devices that are used in connection with the ICP Controllers are operated in a successful, long-lasting and trouble-free manner.
Page 41 The minimum distance between two connectors of a SCSI cable is 20 cm. Avoid cable stubs. If this is not possible, keep the stub length below 5 cm. “Star cabling” are not allowed. Keep the number of transitions from flat to round cables and vice versa as small as pos- sible.
Page 42 Example for a SCSI Flat Ribbon Cable for 8 Bit SCSI Devices (narrow)
Page 43 Example for a SCSI Flat Ribbon Cable for 16 Bit SCSI Devices (wide)
Page 44 Example for a Wide/Ultra2 and Ultra160 Flat Ribbon Cable (1.5 Meters) Examples for Wide/Ultra2 and Ultra160 Round Cables (1 Meters and 3 Meters)
Page 45: Scsi Termination
B.4.2 SCSI Termination In order to ensure a flawless and interference-free signal transmission on the SCSI bus and to minimize the detrimental effects of external noise generators, both ends of the SCSI ca- ble have to be terminated. The SCSI specification prescribes different termination methods for SE and LVDS SCSI bus systems.
Page 46: Icp Scsi Accessories
On hard disks, CD-ROMs, tape streamers, etc., the SCSI ID is normally set through jumpers or small DIP switches. The ICP Controllers offer a far more comfortable method: software switches in the ICP RAID Console or ICP RAID Navigator programs allow you to easily set the SCSI ID of an ICP SCSI channel.
Page 47 SE/LVD Terminator for 68 pin SE or LVDS cables. SE/LVD Terminator for SE/LVD hard disks with SCA connector.
Page 48: Examples
B.4.5 Examples On the following pages, are some examples of correct SCSI cabling. First of all a few general tips: All ICP Controllers have a yellow LED for each Ultra160 SCSI channel. This LED indi- cates the current SCSI-Mode of the corresponding channel. If the LED is lit, the Ultra160 SCSI channel is operating in LVDS-Mode.
Page 49 Internal and external Ultra160 SCSI Hard Disks B.5 ICP Controller Installation Make sure that the ICP Controller is equipped with an appropriate unbuffered SO- DIMM/DIMM (at least 32MB). It is not possible to operate the ICP Controller without RAM. Step 1 Switch off the PCI computer system and remove all cables (first of all the power supply).
Page 50: Icp Controller Function Check
are no further settings required to operate the ICP Controller in a 32 Bit or 64 Bit PCI bus- master slot. ICP Controllers GDT4xy3RZ require a 3.3Volt PCI Slot. Step 4 Push the ICP Controller firmly into the correct PCI bus-master slot. Make sure that the con- troller fits tightly into it, and that the external connectors stick out of the computer case.
Page 51 The other green LED "T" may flicker sometimes (it always lights up during BUS-Master DMA transfers; the brighter it lights, the more DMAs). The yellow LEDs indicate accesses to the devices. They also may flicker occa- sionally as the ICP Controller scans the I/O channels for existing devices. The ICP boot message appears.

Page 55: Quick-Setup
C. Quick-Setup C.1 What is the Aim of Quick-Setup ? In the previous chapter we installed the ICP Controller in a PCI computer and connected the SCSI devices. Now these devices must be prepared in order to run with your operating system.
Page 56 Cluster RAIDYNE® (installed on the GDTx6xxRx). In addition to disk chaining, RAID 0 and RAID 1, RAIDYNE® allows you to install and control Array Drives of the types RAID 4 (data striping with dedicated parity drive), RAID 5 (data striping with distributed parity) and RAID10 (a combination between RAID 0 and 1).
Page 57: The Different Raid Levels
C.2.1 The Different RAID Levels RAID 0 - Data Striping According to the adjusted stripe size (e.g., 128 KB) and the number of hard disks, the data blocks are split into stripes. Each stripe is stored on a separate hard disk. Especially with sequential read and write operations, we can observe a significant improvement of the data throughput.
Page 58 RAID 4 - Data Striping With a Dedicated Parity Drive RAID 4 works in the same way as RAID 0. The data are striped amongst the hard disks. Ad- ditionally, the controller calculates redundancy data (parity information) which are stored on a separate hard disk (P1, P2, ...).
Page 59 RAID 10 - Combination of RAID 1 and RAID 0 The idea behind RAID 10 is simply based on the combination of RAID 0 (Performance) and RAID 1 (Data Security). Unlike RAID 4 and RAID 5, there is no need to calculate parity in- formation.
Page 60: Levels Of Hierarchy Within The Icp Firmware
C.2.2 Levels of Hierarchy Within the ICP Firmware The ICP firmware is based on four fundamental levels of hierarchy. Each level has its "own drives" ( = components). The basic rule is: To build up a “drive“ on a given level of hierarchy, the “drives“ of the next lower level of hierarchy are used as components.
Page 61: Using Cd-Roms, Dats, Tapes, Etc
Generally, each installation procedure passes through these 4 menus, starting with level 1. Therefore: First initialize the Physical Drives. Then configure the Logical Drives. Then configure the Array Drives (e.g. Array Drives with RAID 0, 1, 4, 5 and 10). Finally, configure the Host Drives.
Page 62 Select the menu option Configure Host Drives with ENTER. The list of available Host Drives contains already an entry. There is a RAID 5 Host Drive. After selecting Create new Host Drive ICPCON displays a list of “free” hard disks. These are all the drives which do not belong to a Logical or Host Drive and can be used for new Host Drives.
Page 63: Example 2 - Installing A Mirroring Array - Raid 1
The new Host Drive is assigned a Host Drive Name (here PD_A000) which helps for better identification, especially in configurations with many different Host Drives. The name can be easily changed. C.4 Example 2 - Installing a Mirroring Array - RAID 1 Press the <CTRL><G>...
Page 64: Example 3 - Installing A Raid 5 Disk Array
Move the selection bar with the cursor keys from on entry to another (pressing the SPACE bar again undoes your choice). The Choose Type menu offers four different Host Drive Types. For this example we select RAID 1 and press ENTER. ICPCON displays a warning that all data will be destroyed after confirmation.
Page 65 Select the menu option Configure Host Drives with ENTER. The list of available Host Drives contains already an entry. There is a RAID 5 Host Drive. After selecting Create new Host Drive ICPCON displays a list of “free” hard disks. These are all the drives which do not belong to a Logical or Host Drive and can be used for new Host Drives.
Page 66: Trying To Answer The Initial Questions
ICPCON allows you to limit the hard disk size for this Host Drive. This becomes interesting when you configure disk arrays and you want to make sure that future drives you want to bring into the disk array (for replace- ment or online capacity reasons) fit.
Page 67: Which Level Of Redundancy Is Needed
C.6.2 Which Level of Redundancy is Needed ? To come straight to the point, RAID 0 (data striping) does not imply any redundancy at all (the R in front of the AID is rather misleading). On the other hand, a RAID 0 disk array is pretty fast, since no parity information is required.
Page 68: States Of A Raidyne® Disk Array
C.7 States of a RAIDYNE® Disk Array An Array Drive under the RAIDYNE® operating system can assume seven different opera- tional modes: Idle, Ready, Fail, Build, Rebuild, Expand and Error. C.7.1 "Idle" State This state is characterized by the fact that the redundant information of the disk array has never been entirely created.
Page 69 (*) Replacement either manually, or through hot fix method.
Page 70: Methods For The Replacement Of A Disk Drive
C.8 Methods for the Replacement of a Disk Drive The ICP Controller and the ICP Firmware offer a variety of possibilities to replace a defective disk drive. If and when to use them depends on the physical environment of your server. With some servers the disk drives are just mounted into the server enclosure, they are not removable.

Page 73: Using Microsoft Ms-Dos
D. Using Microsoft MS-DOS After having explained the installation of the ICP Controller and the Host Drives in chapters B and C, we now explain how to install the operating system MS-DOS. By using some ex- amples, we shall demonstrate how to use a CDROM drive (standing for any other Not Direct Access Device) under MS-DOS.
Page 74: Expanded Memory Managers
GDTX000.EXE must be loaded from the first line following the HIMEM.SYS device command in the CONFIG.SYS file. If HIMEM.SYS is not loaded, it must be loaded from the very first line of the CONFIG.SYS file. GDTX000.EXE can be loaded in the UMA. GDTX000.EXE is needed for an optimal use of Windows 3.x.
Page 75: Using A Cdrom Drive Under Ms-Dos
Here the DPMEM starts at D000:0000 and ends at D000:3FFF (D000 is the segment ad- dress). You may also use other utility programs such as Georg Schnurer’s (c’t magazine) CTPCI pro- gram in order to obtain the requested address locations. On this occasion we would like to thank Mr.
Page 76: Example: Using The Asw Software For The Cdrom
At this point we presume that the CDROM drive has been properly connected to the ICP Controller. This includes that the SCSI-ID and the SCSI bus terminators are set in accor- dance with the settings of the already existing SCSI devices (i. e., the SCSI-ID chosen for the CDROM drive is not occupied by another device;...

E. Using Novell NetWare After having explained in chapters B and C the installation of the ICP Controller and the Host Drives, we would now like to give you some hints and pieces of advice on how to in- stall Novell's operating system Novell NetWare. We shall mainly focus on NetWare 3.x, NetWare 4.x and NetWare 5.
Page 86: Novell Netware 4.X/5.X - Using "Ham" Driver
GDTRP400.DSK for NetWare 4.x ASPITRAN.DSK ASPI manager ICPCON CTRLTRAN.DSK Module for (Note: More information about the ICPCON diagnosis tool may be found in a separate chapter in this manual.) if you wish to install NetWare 4.x from a CDROM, you first have to set up the CDROM drive under MS-DOS, following the instructions given in chapter D, section D.6.
Page 87 Change all command lines in STARTUP.NCF and in AUTOEXEC.NCF from DSK to HAM. If CTRLTRAN.DSK is loaded directly, this command line must also be changed (CTRLTRAN.HAM). If the DSK driver is replaced by the HAM driver, the slot number pa- rameter has to be changed as well.
Page 88: Tips And Tricks
Continue with the server installation. 'Down' and 'Exit' the server at the end of the installation. Copy all files except NWPA_411.EXE from the temporary directory to the start-directory of the server. The temporary directory can be deleted afterwards. New installation of NetWare 5.x with ICP HAM driver In order to install NetWare 5.x, we recommend to follow the standard installation proce- dure of the NetWare 5.x server.
Page 89: Installing Netware 4.1 - Wrong Drive Name
(tapes, CDROMs). In general, NetWare gives preference to controllers which support the ASPI Standard (e.g.: ICP, Adaptec). As soon as ASPITRAN.DSK is loaded (Auto-Loading Module) tapes and CDROMs on the ASPI non-compatible controller are no longer recognized.
Page 90: Last Status Information
ASPI interface. For this purpose, the ICP ASPI Manager ASPITRAN.DSK is needed. When loading the regular ICP NetWare driver (for example GDTRP311.DSK), the ASPI Manager is automatically loaded, too. During the installation of ARCserve, choose Adaptec ASPI Manager as interface.

F. Using Microsoft Windows NT or Windows 2000 After having explained the installation of the ICP Controller and the host drives in chapters B and C, we now explain how to install the operating systems Microsoft Windows NT and Windows 2000. For a successful installation, we recommend that you take a close look at the manuals which came with your Windows NT/2000 package.
Page 94 In order to avoid this problem and prevent the risk of data corruption, the Delayed Write function of the ICP cache must be disabled during the complete installation. To do so, use the ICPCON program, choose Advanced Setup, Configure Controller, Controller Settings and switch the Delayed Write function OFF.
Page 95: The Installation
Step 4 – Enabling the CDROM Boot for a SCSI CDROM on the ICP Controller (Note: This step is not necessary if you boot the Windows NT CD from a CDROM which is not con- trolled by the ICP Controller). Load ICPCON and press F4 for the Advanced Setup Mode.
Page 96: Using The Hot Plug Function With Raid Host Drives
At the next system boot the ICP driver is loaded and the existing Host Drives are ready to be partitioned under Windows NT. F.2.3 Using the Hot Plug Function with RAID Host Drives In order to be able to use the Hot Plug function under Windows NT, you my either use ICP RAID Console or ICP RAID Navigator.

Step 1 - Create an ICP Windows 2000 driver disk. You need a 3.5" HD formatted floppy disk. Create from the ICP System CDROM the ICP Windows 2000 driver disk (you can copy file by file or write an image). If you copy file by file do not use the Explorer, because it may not copy all files from the ICP System CDROM.

Page 102: Gdth Driver Parameters
G.5 gdth driver parameters Driver versions older than 1.05 do not support driver parameters. From driver version 1.05 to 1.07 it is necessary to add driver parameters directly in /usr/src/linux/drivers/scsi/gdth.c . From version 1.10 on you may use for the parameters the LILO boot prompt (gdth=...") or in /etc/lilo.conf the append command (append = "gdth=...").

Page 110 SCSI-ID of Not Direct Access Used ICP UNIX UNIX Devices SCSI channel Target ID Having to determine the Target ID and LUN in such a complicated manner might seem rather awkward. However, it is necessary to do so because the ICP Controllers have more than one SCSI channel, whereas UNIX can only manage host adapters with one SCSI chan- nel.

H.4 Instructions on mkdev (ADM) for 3.2v5.x (Open Server) Whenever the program mkdev hd (ADM) is started, you will be asked for the coordinates of the device you wish to install. The driver does not automatically display all devices con- nected, so after the installation you will find a tool named GDTSCAN in the directory '/etc'.

Page 116: Icp Controller As An Additional Controller
I.4 ICP Controller as an additional Controller We distinguish two cases. a.) No ICP Controller has been configured for UnixWare yet. In this case, the ICP driver must be installed from the UnixWare BTLD-Disk by means of the UnixWare desktop and the options "System Setup", "Application Setup". Alternatively, this procedure can be carried out from the UnixWare shell: "pkgadd -d /dev/dsk/f0t"...

J. ICP RAID Console ICP RAID Console (ICPCON) is an extremely helpful and flexible setup and diagnosis tool for the configuration, monitoring, maintenance and tuning of mass storage subsystems which are based on one or more ICP Controllers. Different to the ICP RAID Navigator (a GUI-style application for Windows 9x/NT/2000), ICPCON's user interface is character- oriented and available for all operating systems.

Loading ICPCON on a workstation. In this case, too, the ICP NetWare driver and the auto- loading module CTRLTRAN must have been previously loaded on the fileserver console. In addition, the module CTRLIPX.NLM has to be loaded. This module searches for a file named CTRLIPX.CFG.

These two lines can also be inserted in the .profile file and will then be automatically processed during each login. The ICPCON program itself is copied during the SCO UNIX installation into the /etc directory.

After selecting „Sockets“ and „TCP/IP“ you may enter the IP address of the server (if you would have chosen „SPX/IPX“ ICPCON would scan the network for suitable servers, which have SPX/IPX protocol). After that you may enter your user name and password.

If this counter continues to increase (possibly on other hard disks, too) it is very likely that the cable is not good enough for the selected data transfer rate (cable too long, poor quality of cable and connectors), or that the SCSI bus is not properly termi- nated (too many terminators on the cable, or missing terminator).

At the end of this protocol is a chronological listing of boot messages and other events stored in the Flash-RAM of the ICP Controller. If the buffer is full, the oldest events are de- leted first. In the menu „Configure Controller“ the logging buffer can be cleared with „Clear Log Buffer“.
Page 130 After selecting Configure Host Drives, ICPCON displays a list of already existing Host Drives. With a new system this list will show no entries. In this example there is already one Host Drive available. It’s name is ”RAID 5“ and it is an RAID 5 Array Drive (with approx. 17GB capacity).

However, the position of the Host Drive from which the operating system is booted and the position of the Host Drive from which ICPCON (disk version) was started (both can be the same), cannot be changed.
Page 134 In this example there is one Array Drive in the FAIL state. I.e., the Array Drive is still operating but no longer redundant. After pressing any key, ICPCON displays a list of Array Drives which are candidates for this online automatic repair.
Page 135: Menu Advanced Setup: Configure Controller
The „ERROR“ state of an Array Drive is very critical. There are several procedures in the ICP Controller’s firmware to handle such cases and bring back the Array Drive into operation without loosing data. The most suitable procedure for the specific case, should be elabo- rated with your system administrator or our technical support.

If you confirm with <Y>, ICPCON allows you to limit the size of the Logical Drive. This be- comes interesting when you configure later on an Array Drive with several identical Logical Drives and you want to make sure that you get appropriate spare hard disks in the future. It would be bad luck if the new hard disk would have 17508MB, only.

J.4.6.1 Menu Advanced Setup: Configure Array Drives, Change Drive Name This command allows you to change the name of an Array Drive. The name serves to iden- tify an Array Drive in ICPCON or ICP RAID Navigator. This can be very helpful for configura- tions where several Host Drives of various types are operated by a single controller.

Obviously, no other hard disk may fail until all data has entirely been reconstructed on the Hot Fix drive, because up to that moment, the system is operating without redundancy. Notes: In some literature, Hot Fix drives are also called Hot-Spare drives. You can add or remove Hot Fix drives also with the ICP RAID Navigator.

If you want to add additional drives to the Array Drive, select them from the box on the left side of the window. It is possible to add more than one drive at the same time. If no Physical Drives are offered, you have to use the Hot Plug: Add Disk function first, to add new drives.
Page 178: Remove A Hot Fix Drive
The capacity of the Hot Fix Drive has to be larger or equal than the capacity of the compo- nents of the Array Drive (Example: The Logical Drives of the Array Drive have 4.2GB capac- ity, thus the capacity of the Hot Fix Drive has to be 4.2GB or larger). The spindle motor of the Hot Fix Drive is normally (i.e., when the Hot Fix Drive is not needed) stopped.
Page 179: Remove A Raid 1 Component (Remove A Mirror Drive)
To avoid that problem, you can mirror in a first step a new good Logical Drive to the critical one. When the copying is finished you remove the critical Logical Drive and then carry out a hot plug procedure. To add a RAID 1 component you need to select in a first step a Logical Drive, the master. All suitable Logical Drives (with a capacity equal of larger than the capacity of the master) are shown in a box.
Page 180 The Array Drive is fully operational when in the ready state. All redundant information is present, that is, a hard disk can fail without impairing the functionality of the Array Drive. This is the normal state of an Array Drive. The state ready/expand indicates, that the RAID level and/or capacity are currently migrated/expanded.
Page 181 The error state RAID 4/5 If a second hard disk should fail while the Array Drive is in the fail or rebuild state, it is not possible to continue the working session without restrictions. The disk array is still avail- able for I/Os, but data loss and error messages on the host level are possible.
