ERROR: LVM-DMP bootability is currently enabled. Please execute
"vxdmpadm native disable" to disable the support. Uninstallation of VRTSvxvm
cannot proceed
The exact error advised that DMP's control of the boot disk had to first be disabled. However, performing this step necessitates vxconfigd being up (it couldn't start).
Cause
The issue resulted because the vital first step (documented in the Installation Guide) in not disabling DMP's control of the boot disk was not taken.
Resolution
The procedure followed to back out of this condition and disable DMP's control of the boot device, was as follows:
rm -rf /usr/lib/boot/protoext/disk.proto.ext.chrp.vxvm.disk.rte
and a rebuild of the boot image:
# bosboot -a
bosboot: Boot image is 46913 512 byte blocks.
# shutdown –Fr
Once the machine had rebooted, the VRTSvxvm fileset could then be removed without error.
The procedure to upgrade from 5.1SP1 to 6.0 is clearly documented in the Storage Foundation Installation Guide.
Applies To
AIX 5.3
Volume Manager 5.1SP1
Issue/Introduction
Issue hit was whereby the guidance given to upgrade from 5.1SP1 to 6.0 Volume Manager (not initially disabling DMP's control of the boot disk) was not followed. An attempt at prematurely uninstalling the VRTSvxvm fileset failed as vxconfigd had entered into a state whereby it couldn't start.
It is not possible to uninstall the VRTSvxvm fileset in AIX without first disabling DMP's control.
