The meta-volume is critical for system recovery. The best practice is to mirror the meta-volume across two or more back-end
arrays to eliminate the possibility of data loss. Choose the arrays used to mirror the meta-volume such that they are not required
to migrate at the same time.
Meta-volumes differ from standard storage volumes in that:
● A meta-volume is created without first being claimed,
● Meta-volumes are created directly on storage volumes, not extents.
CAUTION: If the meta-volume is configured on a CLARiiON array, it must not be placed on the vault drives of
the CLARiiON.
Performance is not critical for meta-volumes. The minimum performance allowed is 40 MB/sec and 100 4 K IOP/second.
The physical spindles for meta-volumes should be isolated from application workloads.
Dell EMC recommends the following for meta-volumes:
● Read caching enabled.
● A hot spare meta-volume pre-configured in case of a catastrophic failure of the active meta-volume.
● Minimum of 78 GB.
● Minimum of 20 GB.
If two or more storage-volumes are specified, they must be on two separate arrays if more than one array is present. This
command creates a RAID 1 of all the storage volumes.
Examples
In the following example:
● The configuration show-meta-volume-candidates command displays possible candidates:
NOTE:
Example out put is truncated. Vendor, IO Status, and Type fields are omitted.
● The meta-volume create command creates a new mirrored volume using the 2 specified storage volumes.
● The ll command displays the new meta-volume.
