Chapter 2. Installing a single storage system on a SCSI bus
2 Installing a single storage system
on a SCSI bus
Read this chapter if you are installing only one storage system on a SCSI bus in a
basic configuration. If you are installing two or more storage systems on the same
SCSI bus, skip to Chapter 3.
The procedures in this chapter assume the following:
D
The installation site meets the ac power requirements and operating limits listed
in Appendix A.
D
You have all the cables and cable adapters that you need. Appendix B lists the
cables available for each platform.
D
Someone has installed the SCSI-2 adapter in the server, and if necessary, updated
the server’s driver software for the adapter. Refer to the server’s documentation
for information on installing the adapter.
D
If the SCSI-2 adapter provides a single-ended SCSI bus, someone has connected
a single-ended to differential converter to the adapter to provide a differential
SCSI bus to the storage system.
Attaching the slot matrix diagram
Three sticky-backed labels are shipped with the storage system: a slot matrix showing
the disk drive module locations, and two sheets of stickers for identifying disk
modules. Attach the slot matrix label to your storage-system cabinet so it is visible.
The two sheets of stickers are for labeling the logical units (LUNs). If you are using
the storage system with the factory configuration, use these stickers now to identify
the preconfigured LUNs. (See the “Factory configuration” section in Chapter 1.) If
you are using a custom configuration, save the stickers for the person configuring the
disk modules into logical units (LUNs).
