Re: Alpha 4100 doesn't see disks anymore
I can't believe it. System unavailable, backspace and attachment gone.

Re: Alpha 4100 doesn't see disks anymore
If the disks are connected on the internal controller, check console parameters for termination.

Re: Alpha 4100 doesn't see disks anymore
Can you see the disks or the SCSI controller where those disks are attached in SRM console?

Re: Alpha 4100 doesn't see disks anymore
[You would not have an [SE] scsi cable that is a little over length, or over/under terminated and it 'happened' to work this long?
Good luck,
Hein.

Re: Alpha 4100 doesn't see disks anymore
the problem turned out to be a faulty disk, which blocked the bus. We replaced it, and then all the disks got a new disk device. I have renamed the disks but the disk group is gone. How can I restore that? Unfortunately no volsave made. Can I restore from tape and if, what do I need?
Thanks for any advice,
Michael

Re: Alpha 4100 doesn't see disks anymore
If it is a striped volume the next step is to bring back the replaced disk into the current lsm configuration, recreating the advfs domain and restore from backup.

Re: Alpha 4100 doesn't see disks anymore
the disk group consisted of 3x2 mirrored disks, one of them with two subdisks. Plase point me to the thread with the solution. I must find a solution soon and so far I have only managed to recreate the disk group, but the volrecover does not give any result or error. Attached is the volprint of the disk group.
thanks,
Michael

Re: Alpha 4100 doesn't see disks anymore
finally I got LSM up and running again. I found out, that syscheck also creates a lsm configuration backup. It seem though, that I killed before the data with voldg init. Is my assumption correct?
thanks for all advice,
Michael

Re: Alpha 4100 doesn't see disks anymore
you have not attached any file. If you need an urgent solution why not open a call within the support center instead of still waiting for an reply in this forum?
