As I have described in my last post I stared my work with Oracle VM 3.1 but after all problems with NFS local storage I installed Oracle VM 3.0. When storage issues have been resolved it was a good time run and share information about upgrade process from version 3.0.3 to 3.1. Process itself has been split into two phases - Oracle VM upgrade and Oracle VM Manager upgrade.
Oracle VM upgrade
Oracle VM upgrade is straight forward procedure. I have booted my server from new 3.1 CD and chose upgrade option. After couple of minutes and one reboot new version was in place. Unfortunately repository based on OCFS was not mounted and none of my virtual machines started. But before I dig into it I decided to upgrade Oracle VM Manager.
Oracle VM Manager upgrade
You can download upgrade ISO image from e-delivery (V32481-01) and it has only 123 MB in size. In next step ISO image has to be mounted using loop device and upgrade script should be started.
Post upgrade changes
My first impression after login to upgraded system was that none of two OCFS file systems have been mounted. I checked system logs and looked around in system and I found that only one iSCSI target has been presented. New version of VM means new kernel and new configuration for multipath daemon. In my case second HDD (/dev/sdb) which I used as a block device to my local iSCSI server has been configured with multi path access and I had to change my iSCSI server configuration - instead of using direct path to /dev/sdb2 I need to use path presented through device mapper.

This is strange as I didn't recall this issues from Oracle VM 3.1 / Oracle VM 3.1 Manager installation. It mean that server installation process is different then server upgrade or Oracle VM Manager upgrade has different requirements. Whatever is a root cause let solve it quick. As I mentioned in my last post I have added OEL 5 repository to my Oracle VM yum configuration so I was able to run

I helped and now it least cluster heartbeat file system has been mounted but still no repository. Solution has simple but it took me some time to find it out. I need to rescan all disks in Storage section of Oracle VM Manager and acknowledge all events in Repository section.
Lesson Learned
Event view and acknowledge of all previous errors helps in some stages and made a clean view of current state of Oracle VM.

Marcin
