[-d | --storage-
volumes= volume [,
volume ...]
Creates a temporary meta volume from one or more storage volumes. After the command
completes successfully, the command destroys the temporary meta volume. The specified
storage volumes must not be empty, and must be at the implied or specified cluster.
Type the system IDs for the storage volumes separated by commas.
Specify two or more storage volumes. Storage volumes should be on different arrays.
[-f | --force] Forces the upgrade to proceed without asking for confirmation.
Description
On the metadata volume, each slot stores header information for each storage volume, extent, and logging volume. This
command upgrades the slot count of the active meta volume at the given cluster to 64,000 slots.
By default, the oldest meta volume backup at the cluster serves as a temporary meta volume.
If you specify the -d or --storage-volume option, then the command creates the temporary meta volume from scratch
from those disks. The temporary meta volume is active while the currently-active meta volume is being upgraded. At the end of
the process, metro node reactivates the original meta volume and the temporary meta volume becomes a backup again. Metro
node renames the backup to reflect the new point in time at which it became a backup.
Meta-volumes differ from standard storage volumes in the following ways:
● Create a meta volume from a volum that is not yet claimed.
● Create meta volumes directly on storage volumes, not extents.
If you configure the meta-volume on a CLARiiON array, do not place the meta volume on the vault drives of the CLARiiON.
● Performance is not critical for meta-volumes. The minimum performance allowed is 40MB/sec and 1004KIOP/second.
● Isolate the physical spindles for meta-volumes from application workloads.
Dell EMC recommends the following for meta-volumes:
● Enable read caching
● Pre-configure a hot spare meta-volume in case of a catastrophic failure of the active meta-volume.
● Minimum of 78GB.
● Minimum of 20GB.
If you specify two or more storage-volumes, configure them on two separate arrays if more than one array is present. This
command creates a RAID-1 of all the storage-volumes.
