SVC v7000 vdisk Operations

vdisk Listing Operations

1. List all vdisks
   1. svcinfo lsvdisk
2. List a vdisk by UID
   1. svcinfo lsvdisk -filtervalue vdisk_UID=<vdisk UID>

      ex: svcinfo lsvdisk -filtervalue vdisk_UID=60050768015E91225000000000002C18

3. List a vdisk by name
   1. svcinfo lsvdisk <vdisk name>

      ex: svcinfo lsvdisk VDISKNAME_DB_01

vdisk Host Mappings

1. List host that vdisk is mapped to
   1. svcinfo lsvdiskhostmap <vdisk_name>

      ex: svcinfo lsvdiskhostmap VDISKNAME_DB_01

vdisk Expansion Operations

1. Expand vdisk by name
   1. svctask expandvdisksize -size <size> -unit [b | kb | mb | gb | tb | pb] <vdisk_name>

      ex: svctask expandvdisksize -size 10 -unit gb VDISKNAME_DB_01

vdisk Creation

Standard Volume

1. Create a standard volume
   1. svctask mkvdisk -mdiskgrp <lsmdiskgrp> -iogrp [io_grp0 | io_grp1 | io_grp2 | io_grp3] -size <size> -unit [b | kb | mb | gb | tb | pb] -name <vdisk_name>

      ex: svctask mkvdisk -mdiskgrp MDISK_GROUP_01 -iogrp io_grp0 -size 10 -unit gb -name VDISKNAME_DB_01

Compressed Volumes

1. Create a compressed volume
   1. svctask mkvdisk -mdiskgrp <lsmdiskgrp> -iogrp [io_grp0 | io_grp1 | io_grp2 | io_grp3] -size <size> -unit [b | kb | mb | gb | tb | pb] -compressed -name <vdisk_name> -rsize 5% -autoexpand

      ex: svctask mkvdisk -mdiskgrp MDISK_GROUP_01 -iogrp io_grp0 -size 10 -unit gb -compressed -name VDISKNAME_DB_01 -rsize 5% -autoexpand
