| Private region problem |
## Here i am fixing a "online altused" issue but search the web for different issues as there are a number of ways to the same thing, just remember the vxprivutil command ## obtain the disks private region tag 15 ## run the below script ## if now errors reported above and in the file, then dd back to disk ## repeat for any other bad disks |

vxdg -k -g <group> adddisk <disk>=<device> -k = forces vxvm to take media name of the failed disk & assign it to the new disk |
| Import a group |
vxdg import <group> |
| Import group (clear any flags) |
vxdg import -C <group> -C - clears any exist host flags |
