| Drive State | Meaning |
|---|---|
| Blocked | During a rebuild operation, the ServeRAID controller sets the |
| state of any RAID level-0 logical drives associated with a | |
| failed array to the Blocked state, then, it reconstructs the | |
| data that was stored in RAID level-1 and RAID level-5 logical | |
| drives. | |
| After the Rebuild operation completes, you can unblock the | |
| RAID level-0 logical drives, and access them once again. | |
| However, the logical drive might contain damaged data. | |
| You must either re-create, install, or restore the data from the | |
| most recent backup disk or tape to the RAID level-0 logical drive. | |
| Critical | A logical drive in the critical state that is undergoing a logical |
| Migrating | drive migration (LDM). |
| Critical | The ServeRAID controller uses this reserved state during a logical |
| System | drive migration (LDM). |
| Critical | A RAID level-1 or level-5 logical drive that contains a defunct |
| physical drive is in the critical state. A critical logical drive | |
| is accessible, despite a physical drive failure. | |
| Attention | |
| If the state of the logical drive is critical,replace and rebuild | |
| the defunct drive as soon as possible to prevent the loss of data. | |
| If a second drive fails before the first rebuild completes, you | |
| might lose valuable data. | |
| See 'Rebuilding a Defunct Drive' for more information. | |
| Migrating | The logical drive is undergoing a logical drive migration, that is, |
| a change in RAID levels, a change in logical drive size, or an | |
| increase in free space. | |
| Offline | The logical drive is offline and not accessible. This state occurs if |
| one or more physical drives in a RAID level-0 logical drive is defunct. | |
| This state also occurs when two or more physical drives in a RAID | |
| level-1 or level-5 logical drive are defunct. | |
| Okay | The logical drive is okay. It is in a good, functional state. |
| System | The ServeRAID controller uses this reserved state during logical drive |
| migration (LDM). |
If the state of the logical drive is critical you must replace and rebuild the
defunct drive. See 'Rebuilding a Defunct Drive' for more information.
