Hi,
I've got a 3ware 9550SX-4LP on a dual xeon 3.6GHz machine (no HVM possible). 4 SATA-HDs in RAID 5 installed. xen 3.0.3 with centos-4.4 as xen0. centos-4.4 is also installed on the numerous xenUs. The xenUs are installed in LVs which are formatted as xfs.
Now I'd like to move over to centos 5.0 This is what I thought to be good as an upgrade procedure:
1) install a xen0 to a (bootable) USB hard disk this allows me to go back to my old configuration as soon as I encounter irresolvable probs 2) mount xenU-partitions from xen0 and put modules from the centos5-supplied kernel in there with this test I also test if the 3w_9xxx driver runs smoothly, I'll try bonnie++. 3) run xenUs and test them (Will they run and work?) 4) if all runs good, install xen0 over the old xen0, make backup before. My particular question here is: As it's important to have the 3w_9xxx driver properly loaded with this step, is there anything special I shouldn't forget here?
All this shouldn't take me more than 2 hours. What's your opinion? Any more hints?
Thanks Michael
