RESTRICTIONS

■ Access to all domains is required to to run this command with logical disks specified.

■ Use of this command with the -tpvv option requires a Thin Provisioning license. Contact

■ The -templ option is not valid for volumes that are fully provisioned.

■ The -shared and -wait option cannot be used when creating Thinly Provisioned Virtual

Volumes with the

-tpvv option.

EXAMPLES

The following example creates a 10G TPVV named tpvv1 whose user space is allocated from

the common provisioning group

cpg1:

The following example creates 3 VVs

vv1.2, vv1.3, vv1.4:

The following example creates 2 VVs

vva.0 and vva.1 which may share LDs:

NOTES

■ Using the -shared option can be more efficient when creating a large number of small

volumes since the system will attempt to share the underlying LDs. However, if volumes are

subsequently removed, this can lead to unused space in the LDs that cannot be reclaimed.

Using

-cnt option without the -shared option avoids this problem, but can be inefficient

when creating small volumes due to the overhead of creating a larger number of unshared

LDs for the volumes.

■ Verify the creation of VV by issuing the showvv command. See showvv on page 22.201 for

more information.

■ The maximum VV size is 16 Terabytes.
