SVC v7000 vdisk Operations

vdisk Listing Operations

1. List all vdisks

   svcinfo lsvdisk

2. List a vdisk by UID

   svcinfo lsvdisk -filtervalue vdisk_UID=<vdisk UID>

   ex: svcinfo lsvdisk -filtervalue vdisk_UID=6005076801CF003F2800000000000000

3. List a vdisk by name

   svcinfo lsvdisk <vdisk_name>

   ex: svcinfo lsvdisk VDISKNAME_DB_01

4. List host that vdisk is mapped to

   svcinfo lsvdiskhostmap <vdisk_name>

   ex: svcinfo lsvdiskhostmap VDISKNAME_DB_01

vdisk Creation

Standard Volume

1. Create a standard volume

   svctask mkvdisk -mdiskgrp <lsmdiskgrp> -iogrp <lsiogrp> -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

   svctask mkvdisk -mdiskgrp <lsmdiskgrp> -iogrp <lsiogrp> -size <size> -unit [b | kb | mb | gb | tb | pb] -name <vdisk_name> -compressed -rsize 5% -autoexpand

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

Thin-provisioned Volumes

1. Create a thin-provisioned volume

   svctask mkvdisk -mdiskgrp <lsmdiskgrp> -iogrp <lsiogrp> -size <size> -unit [b | kb | mb | gb | tb | pb] -name <vdisk_name> -rsize 5% -autoexpand -grainsize 32

   ex: svctask mkvdisk -mdiskgrp MDISK_GROUP_01 -iogrp io_grp0 -size 10 -unit gb -name VDISKNAME_DB_01 -rsize 5% -autoexpand -grainsize 32

vdisk Expansion Operations

Standard Volume

1. Expand a standard volume

   svctask expandvdisksize -size <size> -unit [b | kb | mb | gb | tb | pb] <vdisk_name>

   ex: svctask expandvdisksize -size 10 -unit gb VDISKNAME_DB_01

vdisk Mapping Operations

1. Map a vdisk to a host

   svctask mkvdiskhostmap -force -host <host_name> <vdisk_name>

   ex: svctask mkvdiskhostmap -force -host HOSTNAME VDISKNAME_DB_01
