RAID Setup Procedure
Each SBA-7222G-T2 blade module supports four hard drives, two per node, which may
be used to create a RAID array.
Important Notes
Please read the following notes and warnings before setting up your RAID array.
5-1
BIOS Setup
Use the BIOS setup to configure to set RAID options. The BIOS setup procedure is
shown below.
NOTE:
Before adding a new drive to an array, back up any data contained on
the new drive. Otherwise, all data will be lost.
NOTE:
If you stop the B
UILD
or C
LEAR
process on a RAID 1 from the
ACU
, you
can restart it by pressing <C
TRL
> + <R>.
NOTE:
A RAID 1 created using the Q
UICK
I
NIT
option may return some data
miscompares if you later run a consistency check. This is normal and is not a
cause for concern.
NOTE:
The
ACU
allows you to use drives of different sizes in an array.
However, during a build operation, only the smaller drive can be selected as the
source or first drive.
NOTE:
When migrating from single volume to RAID 0, migrating from a larger
drive to a smaller drive is allowed. However, the destination drive must be at
least half the capacity of the source drive.
WARNING:
Adaptec does not recommend that you migrate or build an array on
Windows dynamic disks (volumes), as it will result in data loss.
WARNING:
Do not interrupt the creation of a RAID 0 using the M
IGRATE
option. If
you do, you will not be able to restart or to recover the data that was on the
source drive.
