Recovery group creation

Recovery groups are created using the mmcrrecoverygroup command, which takes the following arguments:
  • The name of the recovery group to create.
  • The name of a stanza file describing the declustered arrays and pdisks within the recovery group.
  • The names of the GPFS cluster nodes that will be the primary and, if specified, backup servers for the recovery group.

When a recovery group is created, the GPFS daemon must be running with the nsdRAIDTracks configuration parameter in effect on the specified servers.

See the mmcrrecoverygroup command for more information.
