Recovery SED

Overview

This function recovers the RAID groups that are in locked status.

"Locked status" indicates that the RAID group is blocked because the SED authentication key could not be obtained from the key server.

Recovery Target RAID Groups

  • All RAID groups that are in the locked status in the storage system.

Conditions that Can Be Recovered by Using This Function

  • Locked status when enabling or forcibly enabling a disk

  • Locked status when forcibly recovering or forcibly enabling a RAID group

  • Locked status when recovering from DE failure

  • Locked status when applying disk firmware

  • Locked status when starting an operation after a disk has been stopped by the Eco-mode

  • Locked status when communication with the key server failed when starting or rebooting the storage system

Caution

  • This function can recover only the RAID groups in locked status. Note that RAID groups in locked status with conditions other the ones listed above cannot be recovered. RAID groups with the "Broken" state may be recovered by using the [Recover RAID Group] function. Note that the [Recover RAID Group] function can be performed by a maintenance engineer who has the "Maintenance Operation" policy.

Note
  • SED recovery from locked status is performed according to the "Recovery Mode" setting of the key group. The "Recovery Mode" setting can be checked in the [Key Group] screen. Refer to the [Key Group] function for details.

    • When "Recovery Mode" is "Automatic", the storage system monitors the RAID group periodically. If a locked RAID group is detected, recovery is performed on the RAID group by the storage system automatically.

    • When "Recovery Mode" is "Manual", use this function to manually recover the locked RAID group.

  • "Recovery Mode" can be specified when creating a key group. Refer to the [Create Key Group] function for details.

  • This function can be used even if a key group is not created or no locked RAID groups are exist. If there are no locked RAID groups that can be recovered, this function completes successfully.
