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

14.8
Command Line Interface Reference InForm OS Version 2.3.1
■ Options –pct and –szs cannot be used in the same instance of issuing the growaldvv
command.
■ One or more of the –szu, –sza, and –szs options must be specified.
■ If enlarging either the administration or snapshot space on the VV and both administration
and snapshot space are zero MB, the administration and snapshot space must be enlarged
together. Both, the
–sza and –szs options must be specified on the command line.
Specifying
–sza or –szs alone is invalid.
■ If the volume being enlarged has snapshot data space and snapshot administration space
with sizes of 0 bytes, the
–sza and –szs options must be specified together.
■ This command cannot be used to grow a volume in such a way that a volume that currently
only has logical disks of a particular device type (Fibre Channel, Nearline, or Solid State
Drive) will have logical disks of multiple device types after the grow operation. If a virtual
volume currently has logical disks of multiple device types, it is possible to grow the volume
using logical disks of any device type. Use
showpd to see the device types of physical disks
in the system.
EXAMPLES
The following example displays the enlarging of a RAID-5 virtual volume with 3+1 parity ratio
named
vv01 by 10 GB:
NOTES
■ A volume can be enlarged while I/O is occurring.
■ When issuing the growaldvv command, the specified options only apply to the newly
enlarged sections of the volume. This can result in a VV that has different characteristics in
its base and grown sections.
■ If options were used in the creation of the original virtual volume (createaldvv) that
were not the default option values, and not specified in the same manner when issuing the
growaldvv command, growaldvv uses the createaldvv default option values. This can
result in a virtual volume that has different characteristics in its base and grown sections.
■ By default, LDs are created using only physical disks with the same device type (by default,
the Fibre Channel device type is used). Use the –p devtype NL option or -p -devtype
SSD
to override this default. Use the showpd command to see the device types of PDs in
the system.
