HP StorageWorks Disk System 212010
SCSI ID Switch
The SCSI ID switch sets the address for the disk drives.
There are three possible settings for the SCSI address switch: A, B, and C. Each
setting assigns a different set of addresses to the disk modules installed in the disk
system. For SCSI address switch setting A, the addresses for the installed disk
modules are (from left to right, looking at the disk system from the front) 0, 2, 4, and
6. For SCSI address switch setting B, the addresses for the installed disk modules are
8, 10, 12, and 14. For SCSI address switch setting C, the addresses for the installed
disk modules are 9, 11, 13, and 15. See Figure 5, below.
SCSI address 7 is reserved for use by the host bus adapter.
