Description
Resurrects the specified dead storage volumes and tests the resurrected device before setting its state to healthy.
A storage volume is declared dead:
● After metro node retries a failed I/O to the backend arrays 20 times without success.
● If the storage volume is reachable but errors prevent the I/O from succeeding.
A storage volume declared hardware dead cannot be unclaimed or removed (forgotten). Use this command to resurrect the
storage volume. After the storage volume is resurrected, it can be unclaimed and removed.
CAUTION: Fix the root cause before resurrecting a storage volume because the volume can be successfully
resurrected only to go back to dead on the next I/O.
This command will not work if the storage volume is marked unreachable.
This command has no ill effects if issued for a healthy storage volume.
LUNs exported from storage arrays can disappear or display I/O errors for various reasons, including:
● Marked read-only during copies initiated by the storage array
● Unrecoverable device errors
● Snapshot activation or deactivation on the storage array
● An operator shrinks the size of a storage volume, causing metro node to refuse to do I/O to the storage volume.
●
100% allocated thin pools
● Persistent reservation on storage volume
● Dropped frames due to a bad cable or SFP
Dead storage volumes are indicated by one of the following conditions:
● The cluster summary command shows degraded health-state and one or more unhealthy storage volumes. For example:
VPlexcli:/clusters/cluster-2/> cluster status
Cluster cluster-2
operational-status: ok
transitioning-indications:
transitioning-progress:
health-state: degraded
health-indications: 1 unhealthy Devices or storage-volumes
● The storage-volume summary command shows the I/O status of the volume as dead. For example:
VPlexcli:/> storage-volume summary
SUMMARY (cluster-1)
