Chapter 6, Deinstalling the VERITAS Volume Manager

Preparing to Remove VxVM

# vxassist mirror volume layout=contig

# vxplex -o rm dis plex_name

Note This operation does not work if you do not have sufﬁcient space on another disk.

◆ Modify /etc/fstab to mount all ﬁle systems using a partition or logical volume

instead of a VxVM volume. Update /etc/fstab for volumes that are not on

rootdg.

Moving Data Out of VxVM Control

BeforeremovingtheVxVM, alltheVxVM volumes mustbe moved toLVM disks.Thiscan

be done in one of the following ways:

◆ Incrementally create LVM volumesand move thedata from each VxVM volume to an

LVM volume one at a time. This procedure is described in “Preparing to Remove

VxVM” on page 72.

◆ Back up the data from each VxVM volume, then remove the VxVM volumes and disk

groups, use vxdiskunsetup(1M) to decommission the disks, put the disks under

LVM control, create LVM logical volumes of the same size as the VxVM volumes, and

restore the data from the backup.

◆ If you have raw data that is not on a ﬁle system, you can do a full backup of the raw

data, then remove VxVM, then recover the backup.
