Command Line Interface Reference InForm OS Version 2.2.4
–tc_lt <number>
Specifies that physical disks with total chunklets less than the number specified are
selected for virtual volume and logical disk creation.
–fc_gt <number>
Specifies that physical disks with free chunklets greater than the number specified
are selected for virtual volume and logical disk creation.
–fc_lt <number>
Specifies that physical disks with free chunklets less than the number specified are
selected for virtual volume and logical disk creation.
–devid <ID>
Specifies that physical disks identified by their device IDs are selected for virtual
volume and logical disk creation. Device IDs can be specified in a comma-separated
list. Issue the
showpd –i command for a list of physical disk device IDs for use with
the
–devid option.
–devtype <device_type>
Specifies that physical disks must have the specified device type (FC for Fibre
Channel or
NL for Nearline) to be used for logical disk creation. Device types can be
displayed by issuing the
showpd –i command. When creating a logical disk, all
physical disks must have the same device type.
-rpm <number>
Disks must be of the specified speed. Device speeds are shown in the K_RPM column
of the showpd -i command.
Disks that satisfy all of the specified characteristics are used. For example, -p -fc_gt 60 -
fc_lt 230 -nd 2 specifies all the disks that have greater than 60 and less than 230 free
chunklets and that are connected to node 2 through their primary path.
–wait <ts>
If the createaldvv command fails to create the logical disks, the –wait option specifies
the number of seconds to wait before attempting to create logical disks again. Logical disks
are not created when there is not a sufficient number of clean chunklets. If
–wait 0 is
issued, space is allocated across any available clean chunklet. Specifying –wait provides
time for chunklets to be cleaned. If this option is not used, the command attempts to create
logical disks indefinitely.
