Defines the virtual volume geometry heads per cylinder value that is reported to the hosts though the SCSI mode pages. The valid range is between 1 to 255 and the default value is 8. -pol [,...] Specifies VV policies. stale_ss Specifies that invalid snapshot volumes are permitted. Failure to update snapshot data does not affect the write to the base volume, but the snapshot is considered invalid. no_stale_ss Specifies that invalid snapshot volumes are not permitted. Failure to update a snapshot is considered a failure to write to the base volume. one_host This constrains the export of a volume to one host or one host cluster (when cluster names can be used as a host name). no_one_host This policy should only be used when exporting a virtual volume to multiple hosts for use by a cluster-aware application, or when "port presents" VLUNs are used. This is the default policy setting. NOTE: An item is specified as an integer, a comma-separated list of integers, or a range of integers specified from low to high. SPECIFIERS [.] Specifies a VV name up to 31 characters in length. If the -cnt option is used, the optional decimal number specifies the name of the first virtual volume (.). The is incremented by 1 for each subsequent virtual volume. The must be an integer from 0 to 999999. All virtual volume names have the same length constraint. [g|G|t|T] Size for the user volume in MB (maximum of 16 T). The volume size is rounded up to the next multiple of 256 MB. The size should be an integer. An optional suffix (with no whitespace before the suffix) will modify the units to GB (g or G suffix) or TB (t or T suffix). If the size is to be taken from a template, this field should be "-". RESTRICTIONS When creating a logical disk, all physical disks must have the same device type.

Defines the virtual volume geometry heads per cylinder value that is reported to the hosts though
the SCSI mode pages. The valid range is between 1 to 255 and the default value is 8.
pol <pol>[,<pol>...]
Specifies VV policies.
stale_ss
Specifies that invalid snapshot volumes are permitted. Failure to update snapshot data does not
affect the write to the base volume, but the snapshot is considered invalid.
no_stale_ss
Specifies that invalid snapshot volumes are not permitted. Failure to update a snapshot is considered
a failure to write to the base volume.
one_host
This constrains the export of a volume to one host or one host cluster (when cluster names can be
used as a host name).
no_one_host
This policy should only be used when exporting a virtual volume to multiple hosts for use by a
cluster-aware application, or when “port presents” VLUNs are used. This is the default policy setting.
NOTE:
An item is specified as an integer, a comma-separated list of integers, or a range of
integers specified from low to high.
SPECIFIERS
<VV_name> [.<index>]
Specifies a VV name up to 31 characters in length. If the
-cnt
option is used, the optional decimal
number
<index>
specifies the name of the first virtual volume (
<vvname>.<index>
). The
<index>
is incremented by 1 for each subsequent virtual volume. The
<index>
must be an integer
from 0 to 999999. All virtual volume names have the same length constraint.
<size>[g|G|t|T]
Size for the user volume in MB (maximum of 16 T). The volume size is rounded up to the next
multiple of 256 MB. The size should be an integer. An optional suffix (with no whitespace before
the suffix) will modify the units to GB (
g
or
G
suffix) or TB (
t
or
T
suffix). If the size is to be taken
from a template, this field should be "
-
".
RESTRICTIONS
When creating a logical disk, all physical disks must have the same device type.
EXAMPLES
The following example creates 3 virtual volumes vv1.2, vv1.3, vv1.4:
cli% createaldvv -cnt 3 vv1.2 1g
The following example creates a RAID-5 virtual volume using disks in cages 0 and 1:
cli% createaldvv -t r5 -p -cg 0,1 vva 1g
The following example creates 2 virtual volumes,
vva.0
and
vva.1
which may share logical
disks:
cli% createaldvv -cnt 2 -shared vva 1g
