The Intelligent Storage Provisioning (ISP) feature is supported up to 5.0 MP3 and has been deprecated from the VxVM 5.1 release. If you have any ISP disk groups, they can be imported using the following command:
# vxdg import ISP_diskgroup
To find out whether the disk group is an ISP disk group. You must check for the presence of storage pools using the following command:
# vxprint
Disk group: mydg TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0 dg mydg mydg - - - ALLOC_SUP - - dm mydg2 ams_wms0_359 - 4120320 - - - - dm mydg3 ams_wms0_360 - 4120320 - - - - st mypool - - - - DATA - - dm mydg1 ams_wms0_358 - 4120320 - - - - v myvol0 fsgen ENABLED 20480 - ACTIVE - - pl myvol0-01 myvol0 ENABLED 20480 - ACTIVE - - sd mydg1-01 myvol0-01 ENABLED 20480 0 - - - v myvol1 fsgen ENABLED 20480 - ACTIVE - - pl myvol1-01 myvol1 ENABLED 20480 - ACTIVE - - sd mydg1-02 myvol1-01 ENABLED 20480 0 - - -
In the sample output , st mypool indicates that mydg is an ISP disk group.
The ISP volumes in the disk group are not allowed to make any configuration changes until it has been upgraded. Attempting any operations such as grow shrink, add mirror, disk group split join, etc, on ISP volumes would give the following error:
This disk group is a ISP disk group. Dg needs to be migrated to non-ISP dg to allow any configuration changes. Please upgrade the dg to perform the migration.
The disk group can be upgraded using the following command:
# vxdg upgrade ISP_diskgroup
After upgrading ISP disk group, all ISP volumes are converted to non-ISP volumes and ISP-only objects are deleted. The ISP-only objects are st pool, volume template, capability, rules, etc. This operation does not affect non - ISP volumes.
