Hello
We have an XP1000 workstation also with Tru64Unix V4.0g .We have two
SCSI HDD (18 GB) and one TLZ10 Tape drive, all on same onboard SCSI
Controller.
Today morning when a student tried to login with his ID and passwd
system didn't allow him to do so. Then we logged in via root account and
to our surprise .profile file of that student were found to be empty.
All the user accounts on this disk showing same behavior .Also console
is logging the Message " Deferred I/O error (at block 5)....." Very
frequently when we try to access data on this disk.
We have faced the similar problem on same HDD in past also. At that time
Compaq engineer formatted the drive using scu and then run verify
command on it .Also that time we had recent system backup so we just
restored the backup .System ran well for 3 months and then again we are
facing the same problem
The real problem is this time we don't have backup of this HDD and very
critical data of PhD students are there. If data is lost some of the
students may lose all their projects.
My question to all of you is
1. If the HDD is having bad blocks/corrupted what is the best and most
reliable method of taking backup of this HDD.
2. What steps can I take to retrieve most of the data from this HDD?
I am scared of running "verify" command or "rebooting" the system
although OS is not on this HDD.
Please reply ASAP
Regards
Vikram
