Create Arrays, Logical Drives, And Assign Iqns On The Totalstorage; Ds300 - IBM TotalStorage DS300 Best Practices Manual

Note: Only 14 drives can be installed in a TotalStorage DS300.
A TotalStorage DS400 can have only 14 drives. To use more drives, up to two
EXP400 expansion units, each with up to 13 drives, can be attached to a
TotalStorage DS400. A feature key is required to enable the external SCSI
channels to attach the EXP400s.
Do not install drives in bay 6 of the EXP400. This SCSI ID is required for the
SCSI chip in the alternate controller.
See 4.8.1, "Create arrays, logical drives, and assign IQNs on the TotalStorage
DS300" on page 114 about the creation of arrays and logical drives in a
TotalStorage DS300. 4.8.2, "Create arrays, logical drives, and access control on
the TotalStorage DS400" on page 131 will explain the same for a TotalStorage
DS400.
4.8.1 Create arrays, logical drives, and assign IQNs on the
TotalStorage DS300
To explain the creation of arrays, logical drives, access control and authentication
settings, a sample configuration is used. This configuration contains the following
items:
First array with two drives as RAID 1 and two logical drives with a size of 10GB.
The logical drives are named COLORADO-BOOT-W and COLORADO-LOG.
Second array with 6 drives as RAID 50 with one logical drive. The logical drive
size will be 150 GB and the name is COLORADO-Mail.
Third array with 4 drives as RAID 10 with one logical drive. The logical drive
has a size of 50GB and the name COLORADO-DB.
One HS20 blade with QLogic iSCSI Expansion Card for IBM ^
BladeCenter for access to the logical drives. Host name is COLORADO.
Host COLORADO has access to the created logical drives only over one path.
One global hotspare will be defined during creation of arrays.
Follow the steps below to create arrays, logical drives and user accounts and
define initiators allowed to access the logical drives:
1. Start IBM ServeRAID Manager (SRM) and connect to a DS300.
