Command Line Interface Reference InForm OS Version 2.3.1
–ss <size_KB>
Specifies the step size in kilobytes using 32, 64, 128, 256, or 512. The default depends on
whether the RAID type is specified. If the RAID type is not specified or is the same RAID type
as the last region of the existing virtual volume, the default is the same step size as the last
region of the virtual volume. Otherwise, the step size defaults to
256 KB for RAID-0 and
RAID-1, and
128 KB for RAID-5. For RAID-6 the step size is a function of the set size.
–ha <port>|<cage>|<mag>
Specifies that the RAID layout must support a failure of one port pair, one cage, or one
mag. The default depends on whether the RAID type is specified. If the RAID type is not
specified or if the same RAID type as the last region of the existing virtual volume is
specified, the default is the same as the last region of the existing virtual volumes.
Otherwise the default is cage. This option has no meaning for RAID-0. Note that snap
admin space is always created with cage availability.
–ch first|last
Specifies the chunklet location preference characteristics, either first (the lowest numbered
chunklets) or last (the highest numbered chunklets). If no argument is specified, the default
characteristic is
first.
–pct <prc>
Specifies the required growth size of the snapshot volume as a percentage of the required
growth size of your volume (as specified with the
-szu option). This option must be used
with the
-szu option, and cannot be used with the -szs option. If not specified, the
default value is zero percent of your user volume.
–wait <secs>
If the growaldvv command fails due to the lack of clean space, the -wait option specifies
the number of seconds to wait for the system to clean the dirty space before returning.
If
-wait 0 is issued, the command returns immediately. If this option is not used, the
command will keep waiting for dirty chunklets to be cleaned if enough space will be
available with the dirty chunklets cleaned.
–dr
Specifies that the command is a dry run and that no logical disks or virtual volumes are
created.
–verbose on|off
Specifies that verbose output is either enabled (on) or disabled (off). If not specified,
verbose output is disabled.
