EFI Boot Device Configuration

Is there a clear how to guide on fixing problems when SAN/storage IDs may have changed? I'm getting an error now also documented in this thread:

Subject: RE: EFI displaying contents of /stand
URL: http://forums.itrc.hp.com/service/forums/questionanswer.do?threadId=1441354

I'm hoping someone can help me figure out how to determine what changed so I can rescan or do what ever is necessary to reconnect with my SAN boot disk.

Thanks!

Re: EFI Boot Device Configuration

In order to search the SAN for possible boot devices you need to adjust the EFIScanLevel of the appropriate FC card. After this, do a "reconnect -r" and "map -r".

Hope this helps!

Re: EFI Boot Device Configuration

Between answering questions for a case I opened with support and reviewing various other threads based on the output of errors I got when booting, I found a partial if not full solution. Basically, I determined that the disk was in good shape, and that somehow booting needed something - it was this:

1. at the efi shell, connected with the device that had my data... fsx:

2. issued the command 'hpux -lq'

where normally, it had been, 'hpux'

More to do on this, but at least we booted!

Re: EFI Boot Device Configuration

"lq" is used to boot in quorum mode when one of your boot disk failed ( if you have 2 disk in vg00)

are you sure this solved your issue?
