Destroying a Disk Group

• Means that the disk group no longer exists
• Returns all disks to the free disk pool
• Is the only method for freeing the last disk in a disk group.

VEA:

 Actions-> Destroyed Disk Group

CLI:

Syntax: vxdg destroy diskgroup

Example: To destroy the disk group olddg and place its disks in the free disk pool:

# vxdg destroy testdg

test4dev# vxdg list

NAME         STATE           ID

testdg       enabled,cds          1209460427.14.test2dev

Reimport a destroyed disk group:

(Because only the dg_name is in that moment destroyed, no the dgid)

#vxdg –f import ----. ---- <host>

Note: after the import, you will be able to start disabled volume with:

#vxrecover –g <dg_name> -sb

test4dev# vxdg -f import 1209460427.14.test2dev

test4dev# vxrecover -g testdg -sb

test4dev# vxdg list

NAME         STATE           ID

testdg       enabled,cds          1209460427.14.test2dev

test4dev# vxdisk list
