Correcting enclosure IDs

When installing a system with expansion enclosures attached, the enclosure IDs might not agree with the physical cabling order. This issue occurs if the controller was previously attached to enclosures in a different configuration, and the controller attempts to preserve the previous enclosure IDs.

About this task

To correct this condition, ensure that both controllers are up, and perform a rescan using the PowerVault Manager or the CLI. The rescan reorders the enclosures, but it can take up to two minutes to correct the enclosure IDs.
NOTE Reordering expansion enclosure IDs only applies to dual-controller mode. If only one controller is available, due to a controller failure, a manual rescan does not reorder the expansion enclosure IDs.

Steps

  1. To perform a rescan using the PowerVault Manager:
    1. Verify that both controllers are operating normally.
    2. Select Maintenance > Hardware.
    3. Select Actions > Rescan All Disks
    4. Click Rescan.
  2. To perform a rescan using the CLI, type the following command:
    rescan
