list openv_util
Description Use this command to calculate the number of LDEV IDs to pass when using the make volumes
command (page 101) to create OPEN-V volumes in a VDEV.
For XP 128/1024 arrays, if the volume to be created is larger than 60 GB the DKC creates a LUSE
volume of equally sized custom volumes. The resulting emulation type is OPEN-V * n ( where n is the
size of the LUSE volume). In this case you must pass n number of unused LDEV IDs to the make
volumes command to create one volume. To create m volumes larger than 60 GB, pass m*n
number of LDEV IDs to the make volumes command.
• This command is supported for OPEN-V LDevs on XP128, XP1024, and XP10000/XP12000
arrays.
• This is a utility command that does not support common options such as -csv [-l | -col
<columns...>] -sa <column> -sd <column> -o <outputfilename> |more |
/p.
• All of the list openv_util arguments are required.
Use list openv_util to query for the following information:
• LdevCount. The number of unused LDEV IDs to pass to the make volumes command.
• OPEN-V Size. The size of the new volumes to be created (openvsize).
• OPEN-V Count. The number of volumes that need to be created of the specified size
(openvcount).
• Emulation Type. The emulation type of the resulting volume. In the case of an XP128/1024, if the
size exceeds 60 GB the LUSE volume of type OPEN-V*n is displayed.
• TotalSpaceNeeded. The total space needed in the parity group for the new volumes of the
specified size to be created.
Syntax list openv_util <pgname> -openvsize <size> -openvcount <num> -fs|-ts
Arguments <pgname>
The name of the parity group (domainID-PGID-VDevID) in which the volumes of the specified size
should be created.
openvsize <size>
The size in megabytes of the OPEN-V volumes to be created.
openvcount <num>
The number of OPEN-V volumes to be created.
-fs
The remaining free space in the VDEV will be considered for the make volumes operation. This
option cannot be used with the -ts option.
-ts
The total capacity in the VDEV will be considered for the make volumes operation. This option
cannot be used with the -fs option.
