Updating an MVG volume using the command-line

To update an existing MVG volume using the command-line

  1. Create a configuration file to update an MVG volume in the following format.
    V7.5 "operation" "update-virtual-volume" string
    V7.5 "virtualVolume" "<mvg-volume>" string
    V7.5 "diskVolume" "<msdp-server1>:<msdp-volume1>:Y" string
    V7.5 "diskVolume" "<msdp-server2>:<msdp-volume2>:Y" string
    V7.5 "diskVolume" "<msdp-server...>:<msdp-volume...>:Y" string
    V7.5 "diskVolume" "<new-msdp-server1>:<new-msdp-volume1>:Y" string
    V7.5 "diskVolume" "<new-msdp-server...>:<new-msdp-volume...>:Y" string

    For example,

    # cat sample-mvg-local.cfg
    V7.5 "operation" "update-virtual-volume" string
    V7.5 "virtualVolume" "sample-mvg-local" string
    V7.5 "diskVolume" "sample-msdp-server1:PureDiskVolume:Y" string
    V7.5 "diskVolume" "sample-msdp-server2:PureDiskVolume:Y" string
    V7.5 "diskVolume" "sample-msdp-server3:PureDiskVolume:Y" string
    V7.5 "diskVolume" "sample-msdp-server4:PureDiskVolume:Y" string
    V7.5 "diskVolume" "sample-msdp-server-new1:PureDiskVolume:Y" string
    V7.5 "diskVolume" "sample-msdp-server-new2:PureDiskVolume:Y" string

    Example to specify an alternative storage server for one or more MVG volumes.

    # cat sample-mvg-local1.cfg
    V7.5 "operation" "update-virtual-volume" string
    V7.5 "virtualVolume" "sample-mvg-local" string
    V7.5 "diskVolume" "sample-msdp-server1:PureDiskVolume:Y:altServer=<alt STS1>" string
    V7.5 "diskVolume" "sample-msdp-server2:PureDiskVolume:Y:altServer=<alt STS2>" string
    V7.5 "diskVolume" "sample-msdp-server3:PureDiskVolume:Y" string
    V7.5 "diskVolume" "sample-msdp-server4:PureDiskVolume:Y" string
    V7.5 "diskVolume" "sample-msdp-server-new1:PureDiskVolume:Y" string
    V7.5 "diskVolume" "sample-msdp-server-new2:PureDiskVolume:Y" string
  2. Apply the configuration changes on the virtual volume.

    nbdevconfig -setconfig -storage_server <mvg-server> -stype PureDisk -configlist <configuration-file>
