Creating and managing volume sets

The following command examples show how to create and manage volume sets.

To create and manage volume sets

  1. Create a new volume set from vol1:

      # vxassist -g dg1 make vol1 10m
      # vxvset -g dg1 make myvset vol1
  2. Create two new volumes and add them to the volume set:

      # vxassist -g dg1 make vol2 50m
      # vxassist -g dg1 make vol3 50m
      # vxvset -g dg1 addvol myvset vol2
      # vxvset -g dg1 addvol myvset vol3
  3. List the component volumes of the previously created volume set:

      # vxvset -g dg1 list myvset
      vol1     0       20480     ACTIVE   -
      vol2     1       102400    ACTIVE   -
      vol3     2       102400    ACTIVE   -
  4. Use the ls command to see that when a volume set is created, the volumes contained by the volume set are removed from the namespace and are instead accessed through the volume set name:

      # ls -l /dev/vx/rdsk/rootdg/myvset
      crw------- 1 root		root		108,70009 May 21 15:37 /dev/vx/rdsk/rootdg/myvset
  5. Create a volume, add it to the volume set, and use the ls command to see that when a volume is added to the volume set, it is no longer visible in the namespace:

      # vxassist -g dg1 make vol4 50m
      # ls -l /dev/vx/rdsk/rootdg/vol4
      crw------- 1 root root 108,70012 May 21 15:43
      # vxvset -g dg1 addvol myvset vol4
      # ls -l /dev/vx/rdsk/rootdg/vol4
      /dev/vx/rdsk/rootdg/vol4: No such file or directory
