createld
DESCRIPTION
This command was deprecated in the 2.2.3 release and will be changed or removed in a future
release. Please use the createvv command in the future.
The createld command allows you to create a logical disk. Unlike the createald command,
issuing the createld command requires that you allocate chunklets for the logical disk created.
SYNTAX
createld [options] <LD_name> <RAID_type> <row_size> <PD:ch>...
AUTHORITY
• Super, Edit
• Any role that is granted the ld_create role.

OPTIONS
–o <owner>
Owner node for the logical disk.
–b <backupowner>

–md <mirrordepth>
Option <raid_type>=1 only, the number of mirror copies in the set.

Option <raid_type>=5 or 6 only, the total number of chunklets in RAID set, including parity.
–ss <stepsize>
Step size is in KB and can take any value in the range of 32 KB to 512 KB. The step size should
be a power of 2 and a multiple of 32. The default value depends on raid type and device type
used. If FC or NL drives are used, the step size defaults to 256 KB for RAID-0 and RAID-1, and
128 KB for RAID-5. If SSD drives are used, the step size defaults to 32 KB for RAID-0, RAID-1 and
RAID-5. For RAID-6, the default is a function of the set size.
–cpsd <CPG_name>

–cpsa <CPG_name>
Adds this logical disk to the specified CPG SA space. Only RAID-1 logical disks may be used for
the SA space.
–ha port|cage|mag
Defines the availability of the logical disk. The default is cage. The availability setting is used to
select the destination chunklets during relocation of failed chunklets.
-domain <domain>
Creates the logical disk in the specified domain. The default is to create it in the current domain,
or no domain if the current domain is not set.
