available. However, the logical drive has lost redundancy (fault tolerance).
You must determine the cause of the problem and correct it.
• Rebuilding – This condition is temporary. When a physical drive has been
replaced, the logical drive automatically begins rebuilding in order to restore
redundancy (fault tolerance). When a logical drive is rebuilding, it will
function and your data is available. However, access will be slower due to
the rebuilding operation.
• Transport Ready – After you perform a successful Prepare for Transport
operation, this condition means you can remove the physical drives of this
disk array and move them to another enclosure or different drive slots. After
you relocate the physical drives, the disk array status will show OK.
Creating a Logical Drive
When you create a disk array, you automatically create one logical drive also. If
the initial logical drive used less than the full capacity of the disk array, you can
create additional logical drives from the same disk array. You can create up to 8
logical drives per array.
To create a logical drive:
1. Click the Subsystem icon in Tree View.
2. Click the Disk Arrays icon.
3. Click the Disk Array icon.
4. Click the Create LD tab in Management View.

Maximum of 16 characters. Use letters, numbers, one space between
words, and underscore. An alias is optional.
6. From the RAID Level dropdown list, choose a RAID level for this logical
drive.
All RAID levels supported by the disk array appear in the list. See “Choosing
a RAID Level” on page 172.
7. Enter a capacity and choose unit of measure (MB, GB, TB).
The default value is the available capacity of the disk array. You can use this
value or any lesser amount.
8. From the Stripe dropdown menu, choose a Stripe size for this logical drive.
The choices are 64 KB and 128 KB. 64 KB is the default. See “Choosing
Stripe Block Size” on page 174.
