4.3 Rolling back to the earlier installed version of Integrity VM

If you must roll back to a previous version of Integrity VM, this section 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 must 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 it is required, it is possible to revert to

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

1. Ensure you have the installation media for the version of Integrity VM that was installed before

Version B.06.30.

2. Before you stop Integrity VM, ensure all guest types are of same type either all VMs or all

vPars.

NOTE: This is applicable only if you are rolling back to a version prior to 6.2.

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

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

# swremove -x autoreboot=true BB068AA VirtualBase

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

# mv /var/opt/hpvm /var/opt/hpvm_6.3

6. Install the earlier installed version of Integrity VM following the directions for installing Integrity

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

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

8. Restore the earlier Integrity VM environment:

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

9. Start Integrity VM.
