One disk is not seen by the system
Applies to
- AFF A700
- DS224C Disk Shelf
- X357 disktype
- 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
Disk Size Shelf Bay Type Type Name
Owner
---------------- ---------- ----- --- ------- ----------- --------- --------
1.60.1 3.49TB 60 1 SSD aggregate Node_root
1.60.2 3.49TB 60 2 SSD aggregate Data1
1.60.3 3.49TB 60 3 SSD aggregate Data1
- Output of '
