create master-volume
Description Creates a volume that is enabled for snapshots. The master volume is created in a specified vdisk
and is associated with a specified snap pool. You can either associate the master volume with an
existing snap pool owned by the same controller, or optionally specify the size of a new snap pool to
automatically create. The vdisk and snap pool must be owned by the same controller.
For use with remote replication, you can create a replication-prepared volume that is intended to be
added to a replication set as its secondary volume. A secondary volume cannot be assigned a LUN
or mapped to hosts.

name
Parameters vdisk vdisk
Name or serial number of the vdisk to create the volume in. For vdisk syntax, see Command syntax
on page 22.
size size[B|KB|MB|GB|TB|KiB|MiB|GiB|TiB]
Sets the volume size using the current base, as shown by the show cli-parameters command. The unit
can be specified as follows:
• If base 2 is in use: B (bytes), KiB (kibibytes), MiB (mebibytes), or GiB (gibibytes).
• If base 10 is in use: B (bytes), KB (kilobytes), MB (megabytes), or GB (gigabytes).
If no unit is specified, the unit is 512-byte blocks.
snap-pool snap-pool
Optional. Name or serial number of the snap pool to associate with the new master volume. For
volume syntax, see Command syntax on page 22. If this parameter is omitted, the system
automatically creates a snap pool that is either 20% of the master volume's size or 5.37 GB,
whichever is larger. Use either this parameter or the reserve parameter.
reserve size[B|KB|MB|GB|TB|KiB|MiB|GiB|TiB]
Optional. Size of the snap pool to create in the vdisk. The default size is either 20% of the volume
size or 5.37 GB, whichever is larger. Use either this parameter or the snap-pool parameter.
NOTE: In rare cases, a large amount of I/O can cause a snap pool that is too small to fill quickly.
This can result in all snapshots being deleted due to the snap pool running out of space. Create snap
pools of at least 50 GB to avoid this situation.
lun LUN
Optional. A default LUN to assign to the new master volume. If this parameter is omitted, no LUN is
assigned. Use either this parameter or the prepare-replication-volume parameter.
prepare-replication-volume
Optional. Specifies to create a replication volume instead of a regular master volume. Use either this
parameter or the lun parameter.
ovms-uid ID
For a volume to be accessed by an OpenVMS host, assign a volume ID in the range 1–32767 to
identify the volume to the host.
