Disk Group Tips

东方蜘蛛

Diskgroups can be moved from one system to another system. On the original system, unmount any volumes in the disk group to be deported and stop them with the command "vxvol stop". Then deport the disk group with the command "vxdg deport".
Move the disks physically to the new system and either reboot the system so that Veritas recognizes the new disks, or use the command "vxdctl enable" to restart vxconfigd.
Import the disks with the command "vxdg import". Then restart all volumes in the disk group with the command "vxrecover -g -sb".
To rename diskgroups during deport/import, run the deport/import command with the argument "-n ". After importing the diskgroup, run the command "vxprint -hrt". The volumes that belong to the imported disk group may be DISABLED. Run the command "vxinfo "volume name" to be sure that the volumes are "startable". Then run "vxrecover -s" to enable each volume.
If the disks in question have been moved due to the crash of the original system, then they will not have been properly deported and will be locked. To unlock the disks, run the command "vxdisk clearimport" or "vxdg -C import". Be sure not to run these commands if the original system has physical access to the disks since that would allow access to the disks from multiple hosts and possibly cause data corruption.
