2) Review the following information about configuring the disk drive subsystem:
a) The SAS disk subsystem in the 58/02 expansion unit can hold up to 18 disk drives. The
disks in this subsystem can be organized in several different configurations depending on
the operating system used, the type of SAS adapter, and the position of the hard-disk-drive
partitions switch.
Notes:
v
The hard-disk-drive partitions switch is located at the rear of the 58/02 expansion unit,
just below the SAS connectors.
v If the hard-disk-drive partitions switch position is changed, you must power the 58/02
expansion unit off and on in order for the 58/02 to sense the new position of the
hard-disk-drive partitions switch.
The SAS disk subsystem in the 58/02 expansion unit is supported by the following
operating systems:
v
AIX
®
v
Linux
v
VIOS
To determine the level of software you need to support the SAS disk subsystem in the
58/02 expansion unit, see IBM Prerequisite.
