Solution
1. Forcing logical drives to come online while you use the PMC storage controller
If the number of offline drives exceeds the tolerance range of the logical drive fault-tolerant method, the management tool interface will display the logical drive state as Failed. In this case, you can use the Force Online function to force the logical drives to come online. The Force Online function for storage controllers is named Re-Enable in UEFI boot mode.
| CAUTION: · Forcing a logical drive in Failed state to come online might cause the existing data on the logical drive to become invalid or unrecoverable. You can reformat and use the logical drive in the OS. · The Force Online operation might change data a logical drive. Before performing this operation, make sure you fully understand the impact. |
To force logical drives to come online:
(1) On the storage controller configuration screen as shown in Figure 64, for example, RAID-P460-M2, select Array Configuration and press Enter.
Figure 64 Storage controller configuration screen
(2) On the screen as shown in Figure 65, select Manage Arrays and press Enter.

2. By the way, the following is how to forcing a logical drive to come online while you use the LSI storage controller.
Forcing a logical drive to come online
When the number of faulty drives exceeds the tolerance range of the logical drive fault-tolerant method, the management tool interface displays the state of logical drives as Offline. In this case, you can use this feature to force logical drives to come online.
| CAUTION: Using this function may change data in the logical drive. Before forcing a logical drive to come online, perform an evaluation task to determine whether the operation can be performed. |
To force a logical drive to come online:
(1) On the storage controller screen, select Virtual Drive Management and then press Enter.
