Display the volumes which meet the criteria for a metro node meta volume.
Contexts
All contexts.
Syntax
configuration show-meta-volume-candidates
Description
Candidate volumes are:
Unclaimed
At least 78 GB capacityIf
CAUTION:
If you configure the meta volume on a CLARiiON® array, do not configure the meta volume on the
vault drives of the CLARiiON.
Dell EMC recommends the following for meta volumes:
Read caching should be enabled
A hot spare meta volume be pre-configured in case of a catastrophic failure of the active meta volume.
Performance is not critical for meta volumes. The minimum performance allowed is 40 MB/s and 100 4 K IOP/second. Isolate
the physical spindles for meta volumes from application workloads.
Availability IS critical for meta volumes. Best practice is to mirror the meta volume across two or more back-end arrays. Choose
the arrays used to mirror the meta volume such that they are not required to migrate at the same time.
