12. 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 RAID level 1E Raid level 5 and RAID level 5E 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 reinstall or restore the data from the most recent backup disk or tape to the RAID level 0 logical drive Critical Migrating A logical drive in the critical state that is undergoing a logical drive migration LDM Critical System The ServeRAID controller uses this reserved state during a logical drive migration LDM when the logical drive is in the critical state Critical A RAID level 1 RAID level 1E RAID level 5 or RAID level 5E 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 refer to Rebuilding a defunct drive on page 105 Migrating The logical drive is undergoing a logical drive migration that is a change in RAID levels a change in logical drive size an increase in free space or a RAID level 5E compression or decompression Offline The logical
