Array storage space still available.
Explanation: You can create another logical drive in this array or make a logical
drive in this array larger.
Physical drives contain unusable capacity.
Explanation: You could redefine your arrays with the same size drive capacities to
avoid wasting space.
There is(are) n ready drive(s) still available. (Where n is a number)
Explanation: You can create another array, add the remaining ready drives to one
of the new arrays, or create a hot-spare drive.
This hot-spare drive will not work for any defined array.
Explanation: This hot-spare drive is not large enough to replace a failed drive in
any array, or there are no redundant logical drives.
Modifying logical drives on ServeRAID SCSI controllers
(ServeRAID series 3, 4, 5, 6, and 7K)
Changing the RAID level:
Note: This action is not supported on the integrated RAID controller.
You can change the RAID levels of currently defined logical drives. To use
Change RAID level, all of the logical drives within the array must be the same
RAID level.
Note:
1. If the logical drive is RAID level-00, 10, 1E0, 50, or 5EE, you cannot
change the logical drive to another RAID level. If the logical drive is
RAID level-0, 1, 1E, 5, or 5E, you cannot change the logical drive to
RAID level-00, 10, 1E0, or 50.
2. You can schedule the logical-drive migration for a later date and time
when you review the configuration changes.
3. You cannot change the RAID level while the logical drive is being
synchronized.
4. (Cluster and failover configurations only) A logical drive will not failover
while undergoing logical-drive migration.
1.
In the Physical devices view, click
(array).
2. Right-click Logical-drive migration and then the appropriate Change RAID
level.
Note: If the array already contains the maximum number of physical drives
(based on the stripe-unit size), the following actions are not available:
v Change RAID level from RAID 0 to RAID 5
v Change RAID level from RAID 1 to RAID 5
3.
If you click one of the following:
v Change RAID level from RAID 0 to RAID 5
v Change RAID level from RAID 1 to RAID 5
