Hi

I have two questions,

First Question:
I had no choice other than restoring a p510 server to factory default in ASMI, Because its console was switching to HMC at startup while I was connected to serial port and no HMC.

Now I want to know if LPAR information is stored in that level, and resetting to factory default will reset the LPAR information.

Second Question:
I can see the console prompt in single user mode,
Hdisk0 and hdisk1 is striped, and lspv hdisk0 seems ok, but lspv hdisk1 shows question marks "?"
In all sections of the output, and server can't boot in normal mode.It hangs when all services started.

At single user mode I can't see /home directory which probably it is on hdisk1.

Probably raid 0 stripe is broken on hdisk0 and hdisk1.

Is there any way to resync the rootvg on two striped hard drives, data should be intact, just LVM seems to have problem.

Thanks for help

Hi,

Yes, the profile information is stored on the HMC so you should be OK. There is an option to rebuild the profile (can't recall where, but documented)

Regarding striping rootvg, why have you done this ? the lspv output indicates you have a problem with hdisk1 and suffering from stale partitions. I'm suprised you can boot to single user mode ! Have you tried

# syncvg -v rootvg

If this resolves your problem, consider mirroring as opposed to striping as this will provide you with redundancy

Hi Steve,

regarding the first question,
Is any LPAR config stored in firmware level which can be lost
if we restore machine to factory default in ASMI menue ?
