Removing Disks

You canremovea diskfroma system and moveit toanother system if thedisk isfailing or

has failed. Before removing the disk from the current system, you must:

1. Stop all activitybyapplications to volumes thatareconﬁguredonthe diskthatis to be

removed. Unmount ﬁle systems and shut down databases that are conﬁgured on the

volumes.

2. Use the following command to stop the volumes:

# vxvol stop volume1 volume2 ...

3. Move the volumes to other disks or back up the volumes. To move a volume, use

vxdiskadm to mirror the volume on one or more disks, then remove the original

copy of thevolume. If thevolumes areno longer needed,they canberemoved instead

of moved.

Before removing a disk, make sure any data on that disk has either been moved to other

disks or is no longer needed. Then remove the disk using the vxdiskadm utility, as

follows:

1. Select menu item 2 (Remove a disk) from the vxdiskadm main menu.

Note You must disable the disk group before you can remove the last disk in that group.

2. At the following prompt, enter the disk name of the disk to be removed:

Remove a disk

Menu: VolumeManager/Disk/RemoveDisk

Use this operation to remove a disk from a disk group. This

operation takes a disk name as input. This is the same name

that you gave to the disk when you added the disk to the disk

group.

Enter disk name [<disk>,list,q,?] disk01
