hi!
i did it last night:
1. powered off correctly the 2 virtual servers.
2. made a ovf-backup of every virtual server.
3. removed and numbered the old harddisks, so that i can use them without any problems again if there will be a problem.
4. startet the server without harddisks, in this case the raid controller will be reseted. (was an info of hp).
5. putted in the new harddisks, and created a raid 6.
6. installed version 5 update 2 customized iso.
7. configured the new vsphere installation.
8. restored the ovf-files.
9. started the virtual servers and updated the vmware tools (incl. restart).
10. ready, everything worked fine.
BUT now i have two warnings:
a) in the configuration view under memory, the 'hp smart array p400 controller : slot1 : hspa1' has a yellow sign. without any information. there is a hint firmware version: 7.22 ... but i have no other information. i did already the actual firmware update dvd from hp, but this did not help.
b) in the event log both of my virtual machines habe not enough video-ram. but i think this is very easy to fix. this should be a configuration option. but i am not able to power off the machines at this time. i will check this if it is possible.
so, the only thing which worries me, is the warning from the raid controller.
greetings,
christian.
