A.3 Featured Highlights This section explains in greater detail the important features of Altos RAIDWatch. A.3.1 Graphical User Interface Altos RAIDWatch’s graphical interface is designed for ease-of-use.
Altos RAIDWatch User Guide The enclosure window also includes Logical view as a sub-function. The Logical view displays the logical relationship among member drives of a logical configuration. Drives belonging to the same logical unit will be displayed in the same color for ease of identification. A.3.3 Powerful Event Notification Function Altos RAIDWatch can notify system administrators of event occurrences and status changes in the disk array system.
Introduction A.4 Conceptual Foundation In order for Altos RAIDWatch to function properly, different software modules must be correctly installed on different servers and stations in a given LAN or WAN. Assuming that a given network has multiple RAID systems, one RAID connected server will need to be chosen as the main server. This point is particularly important if Altos RAIDWatch will be operated via web browsers as the main server will need to be a web server.

Altos RAIDWatch User Guide 10.3 Displaying the Event Log Altos RAIDWatch Manager can display a running log of all events that occur in the disk array system ranging from simple notifications, to warnings, to alerts. Note The Event Log only displays events that occur while Altos RAIDWatch Manager is running. Click on the Event Log command button or select the Event Log command from the Open menu.
System Monitoring • The Read/Write Statistics window displays the amount of data being read from and written to the disk array system, in MB per second. Read values appear in blue and Write values in red.
The NPC Chapter 11 The Notification Processing Center The Notification Processing Center (NPC) is a notification application that enables users to configure notifications that are transmitted when various disk array events occur. The NPC makes it possible to manage (or monitor) the disk array system even when the administrator is away from the manager station.
Altos RAIDWatch User Guide 11.1 Before You Begin 11.1.1 About NPC Altos RAIDWatch NPC provides five methods of sending notifications: • Fax • Pager • E-mail • Broadcast • SNMP Traps You can use any or all of the notification methods mentioned above. In order to use a particular method, you must have the proper hardware (like a modem for pager notification) and software (like Windows NT with the window messaging subsystem for e-mail message notification) installed in your system.
The NPC 11.3 Redundant NPC Modules Figure 11–1 Redundant NPC Modules The NPC and Primary Agent should be, as shown in Figure 11–1, installed redundantly on two different servers in case the Primary Agent or module should fail. If the Primary Agent or NPC should fail, the Primary Agent and NPC installed on another server will continue event notification.
The NPC When you have finished, click Add to allow NPC to use this modem. Next, choose another NPC item to configure or click Close to save changes and exit the installation procedure. Important A pre-configured modem can only be removed from the list of Available Modems after all references to the modem have been removed.
Altos RAIDWatch User Guide When Personal Fax is installed, only administrators can send faxes. NPC has altered the associated configurations to eliminate this limitation. However, it is recommended to log in as an Administrator. For normal users to send faxes, you may check your write access in the registry key: HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Print/Printers/Fax/.…...
The NPC Figure 11–5 : FAX Topology Add Fax Mail Transport and Internet Mail as the active services to Windows Messaging profile. Figure 11–6 Add Fax Mail Transport and Internet Mail Since NPC depends largely on the fax service installed to the MAPI of Windows NT for the delivery of fax messages, most fax notification parameters are configured through this software package.
Altos RAIDWatch User Guide • Initializing String: is a standard AT command set initialization command string. The default is &F1X0M0 and should be appropriate for most modems. If you need to change it, consult your modem manual for the correct AT command string. The Initializing String is applied for fax and pager service on Unix-based systems.

It includes the following topics: • Common oversights, B.1 on page 177. • Error codes, B.2 on page 178. • Error messages, B.3 on page 179. B.1 Common Oversights Check the following first before you run Altos RAIDWatch or if you are having trouble.
Altos RAIDWatch User Guide Check the Primary and Secondary agents #ps -eaf|grep primary #ps -eaf |grep secondary If either program is not running, please open a terminal session and run it manually. IP Settings: Each RAID host server must have a unique IP address assigned. Check the IP address of each RAID host.
Troubleshooting What You Can Do: Check your network environment to determine whether or not the Primary agent is available. Use a “ping” utility to see if the server exists on the network. Code: RC=2 • Meaning: The Primary agent did not understand the last Altos RAIDWatch Manager command. What You Can Do: Please check the firmware version of controller to see if it is compatible with your version of Altos RAIDWatch.
Altos RAIDWatch User Guide Explanation: Please assign one PID to each drive channel. • Message: Channel settings failed! Explanation: Please check the channel settings. • Message: Drive channel can only have one ID! Please remove ID from PID list first, and then add.
Troubleshooting • Message: Setup redundant controller failed! Explanation: Check the redundant controller configuration. See if the PID and SID of drive and host channels are all correct and if the logical drives (volumes) are correctly assigned. All other Altos RAIDWatch Manager error messages should be fairly self-explanatory.
RAID Levels Appendix C RAID Levels This appendix provides a functional description of Redundant Array of Independent Disks (RAID). This includes information about RAID and available RAID levels. C.1 RAID Description Redundant Array of Independent Disks (RAID) is a storage technology used to improve the processing capability of storage systems.
Altos RAIDWatch User Guide 2 GB Hard drive 3 GB Hard drive 1 GB Hard drive 2 GB Hard drive 2 + 3 + 1 + 2 = 8 GB Logical Drive C.3 RAID 0 RAID 0 implements block striping where data is broken into logical blocks and striped across several drives.
RAID Levels In disk mirroring, the total disk capacity is equivalent to half the sum of the capacities of all SCSI drives in the combination. Thus, combining four 250GB SATA drives, for example, would create a single logical drive with a total disk capacity of 1TB. This combination of drives appears to the system as a single logical drive.
Altos RAIDWatch User Guide C.6 RAID 3 RAID 3 implements block striping with dedicated parity. This RAID level breaks data into logical blocks, the size of a SCSI disk block, and then stripes these blocks across several drives. One drive is dedicated to parity.
Glossary Glossary Fibre (Also known as “fibre channel.”) . A device (in the case of RAID, a data storage device) protocol capable of high data transfer rates. Fibre channel simplifies data bus sharing and supports not only greater speed, but also more devices on the same bus. Fibre channel can be used over both copper wire and optical cable.
Altos RAIDWatch User Guide Parity . Parity checking is used to detect errors in binary-coded data. The fact that all numbers have parity is commonly used in data communications to ensure the validity of data. This is called parity checking. Primary Agent .
Glossary Write-back Cache . Many modern disk controllers have several megabytes of cache on board. Inboard cache gives the controller greater freedom in scheduling reads and writes to disks attached to the controller. In write-back mode, the controller reports a write operation as complete as soon as the data is in the cache.
