A.1.5 Number of Volumes

There are the following limits to the number of volumes that can be created within a group in the root class:

• The number of volumes with the physical slice attributes set to "on" is limited to a maximum of 6.

• Volumes with the physical slice attributes set to "off" cannot be created.
  
  

There are the following limits to the number of volumes that can be created within a group or a single disk in the local class or shared class:

• You can create a maximum of 6 volumes with their physical slice attribute set to "on."

• You can create a total of 1024 volumes with their physical slice attribute set to "on" or "off."

• You cannot create a volume with the physical slice attribute set to "on" in a stripe group or a concatenation group.

• You cannot create a volume with the physical slice attribute set to "on" in a shadow class regardless whether the physical slice is registered with VTOC.

In addition, there are the following limits to the number of volumes that can be created within a class:

• For the root class, the number is limited to a maximum of 256.

• For a local class, the number is limited to a maximum of 6144.
  However, when groups are nested, the nested group can contain a maximum of 6144 volumes and lower level groups collectively.
