HP-UX vPars and Integrity VM V6.1.5 Administrator Guide (5900-2295, April 2013)

A Rolling back to the previously installed version of Integrity

In the unlikely event that you need to roll back to a previous version of Integrity VM, this appendix

provides the information needed to perform the rollback. The preferred method for rolling back to

a previously installed version of Integrity VM is to restore the system image that was backed up

before installing the current version of Integrity VM on the VSP. Because this is not always possible

for all users the following method should work.

The VSP and guest configuration files are stored at /var/opt/hpvm. Because configuration files

for newer versions of Integrity VM are not normally compatible for earlier versions of Integrity VM,

a copy is made of the contents of /var/opt/hpvm to the /var/opt/hpvm/backup directory

(except the ./guest-images and ./backups directories). If need be, it is possible to revert to the

older version of Integrity VM using the backups directory and the following process:

1. Make sure you have the installation media for the version of Integrity VM that was installed

before version B.06.10.05.

2. Stop Integrity VM (/sbin/init.d/hpvm stop)

3. Remove Integrity VM V6.1.5 software (This causes a system reboot.).

# swremove -x autoreboot=true BB068AA VirtualBase

4. Move the /var/opt/hpvm area aside:

# mv /var/opt/hpvm /var/opt/hpvm_6.1.5

5. Install the previously installed version of Integrity VM following the directions for installing

Integrity VM in this manual for that version. This also causes a system reboot.

6. Once the system is back up, log in and stop Integrity VM (/sbin/init.d/hpvm stop).

7. Restore the previous Integrity VM environment:

# cd /var/opt/hpvm_4.3/backups; tar -cpf - | cd /var/opt/hpvm; tar -xpf -

8. Start Integrity VM.
