CH A P T E R Product and Architecture Overview This chapter provides a brief overview of the SANnet II 200 SCSI array, which is an LVD/SE device. Topics covered in this chapter are: “SANnet II 200 SCSI Arrays” on page 1-1 ■...
For information about specifications and agency approvals, see Appendix A. Array Configurations The SANnet II 200 SCSI array can be used in the following configurations: Single-controller configuration. A RAID array can be configured with a single ■...
SCSI Architecture Each RAID array has five channels with the following defaults: Channels 1 and 3 are host channels connected to servers. Any SANnet II 200 SCSI ■ array host channel can be reassigned as a drive channel to connect to an expansion unit.
A label on the lower lip of an array chassis, underneath the front bezel, indicates whether it is a JBOD array or a RAID array. For instance, “SANnet II 200 AC JBOD” refers to an alternating-current version of a SANnet II 200 JBOD array, “SANnet II 200 DC JBOD”...
■ For information about specifications and agency approvals, see Appendix A. Field-Replaceable Units (FRUs) This section describes the FRUs contained in the SANnet II 200 SCSI array. 1.5.1 RAID I/O Controller Modules A dual-controller configuration offers increased reliability and availability because it eliminates a single point of failure, the controller.
The hot-serviceable I/O expansion modules provide four ports but do not have battery modules or controllers. I/O expansion modules are used with I/O controller modules in non-redundant SANnet II 200 SCSI arrays, and in expansion units and SANnet II 200 SCSI JBODs.
For information about supported versions of these operating systems, refer to Note – the SANnet II 200 SCSI Array Release Notes. The array does not require any host-based software for configuration, management, and monitoring, which can be handled through the built-in firmware application. The...

Do not block or cover the openings of your Dot Hill product. Never place a Dot Hill ■ product near a radiator or heat register. Failure to follow these guidelines can cause overheating and affect the reliability of your Dot Hill product. 2-2 SANnet II 200 SCSI Array Installation, Operation, and Service Manual • June 2005...
(+/–) 5 percent. The customer facilities must provide suitable surge protection. Electrical and Power Specifications All SANnet II 200 SCSI arrays require two independent power sources. Each array has two power-supply-and-fan modules for redundancy. Each SANnet II 200 AC array requires two 115-VAC/15A or two 240-VAC service outlets.
It is helpful to create a sketch or layout map to indicate the exact location for the SANnet II 200 SCSI array installation as well as the location of the hosts, console, and Ethernet connections that will be connected to it.
2.6.2 Tabletop Placement SANnet II 200 SCSI arrays can be positioned on a desk or a table. Follow these guidelines when preparing a tabletop placement for your system. Choose a desk or a table that can support 57.2 pounds (26 kg) for one fully- ■...
A console with at least one serial port connection is necessary for installation and configuration of your SANnet II 200 SCSI array. Once you have configured your array with an IP address, an Ethernet port can also be useful for configuring the array.

4.13 Remaining Steps SANnet II 200 SCSI arrays are preconfigured with a single RAID 0 logical drive mapped to LUN 0, and no spare drives. This is not a usable configuration, but it enables in-band connections with management software. You must delete this logical drive and create new logical drives.
Do not use the option shown at the bottom of the example. This option is skip reserved for support personnel performing testing. 4.15 Power-Off Procedure You might need to power off the array (both power supplies) if you relocate the array or perform certain maintenance procedures with associated servers.

It is rare for two or more drives to fail at the same time. To minimize the chance of this happening, regular RAID integrity checks should be performed. For RAID 3 and RAID 5, this can be done using the array console’s “regenerate Parity” option, or using the SANscape CLI command.

You must ensure that the length of all cables to any connected nodes, as well as the internal bus length of .5 meters (1.6 feet) internal to the SANnet II 200 JBOD array and the internal bus length of the host, is less than 12 meters (39.4 feet) in total. Also include the jumper cable length of .3 meters (.98 feet) if the JBOD is being used in a...
If you connect two hosts to the same channel, you must change the scsi- Note – initiator-id of one host adapter as described in the host adapter documentation. When either of these hosts is subsequently booted, SCSI reset warnings are displayed on the other host.
IDs change after you power off, change the cabling, and then power on. If you change physical drive IDs on the array, ensure that your application points to the correct IDs. SANnet II 200 SCSI Array Installation, Operation, and Service Manual • June 2005...
Connections Host Host Bus cable Host cable Figure B-2 A Single-Bus JBOD with Two Host Connections (Rear View) The following table shows the default physical drive IDs for a 12-drive JBOD when you set up a single-bus configuration. The physical drive IDs are 0–13, with IDs 6 and 7 reserved for host HBA connections.

In a split-bus configuration, if each port is connected to a different server, the Note – program can only monitor the JBOD from the server connected to port B. SAF-TE information is not displayed for port A. B.8.2 Viewing Component and Alarm Characteristics In SANscape, to view environmental component and alarm characteristics, use the View Enclosure window or, for some components, the main window.
The SANscape CLI supports JBOD arrays. However, because JBOD arrays do not have a RAID controller to manage the disks, this command-line interface support is limited to the following commands: ■ about download safte-firmware ■ B-12 SANnet II 200 SCSI Array Installation, Operation, and Service Manual • June 2005...

LUNs, up to 128 /kernel/drv/sd.conf LUNs, which can be used in a single SANnet II 200 SCSI array. Then reboot the host. You might want to allow a few extra LUNs for flexibility over the coming months, but generally most administrators minimize the number of unused LUNs because each LUN causes a seven-second delay when you reboot the host.
Page 139
The following example file sets up targets 1 and 3 with a total of 41 LUNs (LUNs 0 through 31 on target 0, and LUNs 0 through 8 on target 3). Default LUNs are listed first, followed by new LUNs. # Copyright (c) 1992, by Dot Hill Systems Corp. #ident"@(#)sd.conf1.998/01/11 SMI" name="sd" class="scsi" class_prop="atapi"...
By default, a Solaris host is configured for one host LUN per SCSI target, which is not enough LUNs for a SANnet II 200 SCSI array. You must edit the appropriate onboard HBA driver configuration file to add more targets and LUNs, up to 32 LUNs per logical drive, and a maximum of 128 LUNs per SANnet II 200 SCSI array.
