Re: Mirror disk failed on Alpha ds10 (Tru64 Unix)
What kind of mirroring are you using, hardware (RAID controller) or LSM?
What is the OS version?

Re: Mirror disk failed on Alpha ds10 (Tru64 Unix)
# volprint -Aht
Then we will see if you are using LSM.
Maybe the best would be the following:
Do
# sys_check > /tmp/config.html
Zip the file and post it as attachment.

Re: Mirror disk failed on Alpha ds10 (Tru64 Unix)
Sorry for the delay, but the sys_check command takes a long time and there was a system disk space.
Plesae find attached the requested file.
Apparantly the LSM is installed.
Please I need the method to change the LSM mirror bootable disk.
NB: based on the attached file, apprently the disk is EIDE 80GB, can you confirm, and if possible to have the disk P/N that I should ordered.
Thanks in advance

Re: Mirror disk failed on Alpha ds10 (Tru64 Unix)
Sory for delay, I was away from work and will be some time.
First, you have 40 GB disks, not 80 GB.
Part number is 3X-RE58A-BA (40-GB 7,200 rpm IDE (UDMA) disk drive).
Looks like you have problem with dsk0. To see which disk is dsk0 use this:
# dd if=/dev/rdisk/dsk0c of=/dev/null
Disk which has activity is dsk0.
Generic method how to replace bad disk is (
I will write exact commands for your case later):
1. Remove the failed disk from the disk group retaining the media
records thus
# voldg ├в g mydg ├в k rmdisk media_name
2. Remove the disk access record
# voldisk rm disk_access_name
3. Restore the disklabel
#disklabel ├в wr rz?? disktype
(assuming no copy of the label was saved)
#disklabel ├в r ├в R rz?? /saved_label disktype
(if the label was saved)
4. Initialise the new disk for use with LSM
# voldisksetup ├в i rz?? nconfig=? nlogs=? privlength=??
(assuming no copy of the label was saved)
# voldisk ├в f init rz?? offset=16
(if the label was saved)
5. Associate the new disk to a disk media record/disk group
# voldg ├в g mydg ├в k adddisk media_name=disk_access_name
6. Recover(synchronise) the plexes in the diskgroup
# volrecover ├в g mydg -sb

Re: Mirror disk failed on Alpha ds10 (Tru64 Unix)
I forgot to say that you have problem with boot disk and it requires special procedure.
You can see a method how to do it in attached file.
I hope I did not forget something. It would be good if someone else check my procedure (Michael, Johan or somebody else) since I have a headache.
But I think my procedure should work OK.
