Configuring a New
Storage System
Read this section if you are configuring a new storage system. A new storage system is
one that was not already connected to a server when you started the installation procedure.
Before You Start
You need the completed storage system disk information worksheet from Procedure 1,
"Planning Your Fibre Channel Storage System Configuration," on page 1 or Procedure 4,
"Installing an iSCSI Storage System," on page 51.
STEP 1. Start up Navisphere Express. See Procedure 29, "Running Navisphere Express," on
page 163.
STEP 2. Create a hot spare.
A hot spare is a single global spare disk that serves as a temporary replacement for
any failed disk in the storage system. The storage system automatically reconstructs
data from the failed disk onto the hot spare, so the data is always available.
In the Navisphere Express navigation pane, under Manage, click Hot Spare. For details on
creating a hot spare, use the Navisphere Express Help Center.
STEP 3. Create one or more disk pools on which to create virtual disks.
A disk pool is a set of disks, all with the same capacity and redundancy, on which
you create one or more virtual disks. A RAID 5 disk pool must include at least three
disks and a RAID 1/0 must include at least two disks. The storage system supports
a maximum of six disk pools.
In the Navisphere Express navigation pane, under Manage, click Disk Pools. For details
on creating a disk pool, use the Navisphere Express Help Center.
For an SSR212PP2f (dual-SP) storage system, you should create at least two disk pools
since the software assigns each disk pool you create to an SP as follows: disk pool 1 to SP
A, disk pool 2 to SP B, disk pool 3 to SP A, and disk pool 4 to SP B. All the virtual disks
you create on a disk pool are automatically assigned to the same SP as the disk pool, so if
you create only one disk pool on the storage system, all virtual disks on the storage system
are assigned to SP A and all data received or sent goes through SP A only.
The disk modules marked 0 through 3 contain storage system software or reserved
space according to their slot assignment. Do not move any disk marked 0 through 3
from its assigned slot. Remove it only to replace the disk module. Part of the space
