Hi,
VxVM can be removed from a server but care must be taken to follow the proper
procedures and not just swremove the products.
The following steps will remove VxVM properly.
o Determine if there are disk groups other than rootdg by running the
following:
# vxdg list
NAME STATE ID
rootdg enabled 997120777.1025.rbox
datadg enabled 1000301278.1606.rbox
The above command reveals two diskgroups; rootdg,datadg.
o Identify volumes in the disk groups using vxprint -htr.
/etc/fstab can also be checked for volumes with device files beginning
with /dev/vx/dsk but this will obviously only show volumes that have
filesystems mounted at boot and swap assigned at boot.
o Backup or copy the data from VxVM volumes to LVM logical volumes. This can
be done with fbackup, tar, cpio, etc.
o Unmount any VxVM volumes with filesystems and remove those entries from
/etc/fstab.

/dev/vx/dsk/datadg/datavol01
51200 1117 46960 2% /datavol01
# umount /datavol01
o Remove all diskgroups except for rootdg with the following command:
vxdg destroy groupname
For example:
vxdg destroy datadg
o Stop the VxVM daemons with the following commands:
vxdctl stop
vxiod -f set 0
o Remove the VxVM product.
If the HP VxVM product B9116AA is installed which is the full version then run:
swremove -x autoreboot=true B9116AA
Next, run the following to remove the base product:
swremove -x autoreboot=true B7961AA
The disks used in rootdg or other disk groups can now be used with LVM.

Jerome
