Creating and managing volume sets

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

 To create and manage volume sets

• Create a new volume set from vol1:

# vxassist make vol1 10m

# vxvset make myvset vol1

• Create two new volumes and add them to the volume set:

# vxassist make vol2 50m

# vxassist make vol3 50m

# vxvset addvol myvset vol2

# vxvset addvol myvset vol3

• List the component volumes of the previously created volume set:

# vxvset list myvset

VOLUME INDEX LENGTH STATE CONTEXT

vol1 0 20480 ACTIVE -

vol2 1 102400 ACTIVE -

vol3 2 102400 ACTIVE -

• 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

1 root root 108,70009 May 21 15:37 \

/dev/vx/rdsk/rootdg/myvset

• 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 make vol4 50m

# ls -l /dev/vx/rdsk/rootdg/vol4

crw-- 1 root root 108,70012 May 21 15:43

/dev/vx/rdsk/rootdg/vol4

# vxvset addvol myvset vol4

# ls -l /dev/vx/rdsk/rootdg/vol4

/dev/vx/rdsk/rootdg/vol4: No such file or directory
