Device Naming

DiskSuite accesses SPARCstorage Array disks exactly like any other disks, with one important exception: the disk names differ from non-SPARCstorage Array disks.

The SPARCstorage Array 100 disk naming convention is:

c[0-n]t[0-5]d[0-4]s[0-7]

In this name:

• c indicates the controller attached to an SSA unit

• t indicates one of the 6 SCSI strings within an SSA

• d indicates one of the 5 disks on an internal SCSI string

• s indicates the disk slice number

• Strings t0 and t1 are contained in tray 1, t2 and t3 in tray 2, and t4 and t5 are in tray 3

The SPARCstorage Array 200 disk naming convention is:

c[0-n]t[0-5]d[0-6]s[0-7]

In this name:

• c indicates the controller attached to an SSA unit

• t indicates one of the 6 targets (trays) within the SSA unit

• d indicates one of the 7 disks on an internal SCSI string

• s indicates the disk slice number

Older trays hold up to six disks; newer trays can hold up to seven.

The main difference between the SSA100 and SSA200 is that the SSA100 arranges pairs of targets into a tray, whereas the SSA200 has a separate tray for each target.
