3PAR InForm® OS 2.3.1 CLI Reference (320-200166 Rev B, March 2010)

11.21
InForm OS Version 2.3.1 Command Line Interface Reference
RESTRICTIONS
■ Logical disks must be available to run the createavv command. Issue the createald
command to create logical disks. See createald on page 11.3 for more information.
■ The <adminspace_LD_ID>. <adminsize>, <snapspace_LD_ID>, and <snapsize>
specifiers cannot be used if the
createavv -cpg command is issued.
EXAMPLES
The following example displays the creation of Virtual Volume vv0 with its user space set to
256 MB and its administrator space set to 256 MB:
NOTES
■ Verify the creation of virtual volumes by issuing the showvv command. See showvv on
page 22.201 for more information.
■ A newly created logical disk is guaranteed to be clean. Chunklets of logical disks that are
removed are cleaned before they are reused. However, regions of a logical disk that were
previously used (for example, by another Virtual Volume) can contain data from its
previous use. If these regions of the logical disk are mapped to your user space in a Virtual
Volume, that data can be visible to the host that the Virtual Volume is exported.
If this is a concern, remove logical disks when the Virtual Volume is removed and use only
newly created logical disks for your user space. Previous data in logical disks used for
snapshot data space or snapshot admin space is not visible to you because these spaces are
only visible after being written with new data.
■ For this command, MB = 1048576 bytes.
■ This command was deprecated in the 2.2.3 release and will be changed or removed in a
future release.
