One disk is not seen by the system
Applies to
- AFF A700

- 4-node cluster
Issue
- The cluster is missing one disk
- Each node has two spare disks, one for each pool
- Only seven spare disks are seen, eight are expected
- There are no broken, unassigned or unsupported disks
- When the disks are listed, a disk is missing, in this example disk 1.60.0 (
Bay 0
) is skipped
Example:
Cluster::> disk show -container-type aggregate
Usable Disk Container Container
