Configuring a New Storage System
Configure a New Storage System
1. Locate your completed storage-system configuration planning
worksheet so you can refer to it in the steps that follow.
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.
To create a hot spare -
in the Navisphere Express navigation
pane, under
Manage
, click
Hot Spare
. For details on creating a
hot spare, use the Navisphere Express Help Center.
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.
To create a disk pool -
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 AX100 (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 an
AX100 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 on these disks is reserved or preloaded with
system data, and as a result, is not available for your data. If you combine
