root disk crashed!!!!
Posted on 2004-04-14
i am having an E3500 sun server with solaris 8 (patch level 12) with a D1000 sun storedge attached to it....the root disk of this server having /,swap,/var & /export/home has crashed.
i am trying to restore the same from my backups which was taken in multiuser mode with all the users logged off & no activity on the disk during the period.
i am doing restoration by booting through the sun cdrom in single user mode & restoring it through "ufsrestore rvf".
now my new disk is getting detected at " probe-fcal-all" & also while booted through cd but on loading through the root disk on which all data was recenly backed up,the following happens:
1.>it starts loading the os
3.>then gives errors like
c0t0d0s1 not found
c0t0d0s0 not found , these are my swap & root partitions respectively.
then it comes to single user mode and asks for passwd:
here it accepts my old root passwd but on giving " format" command it shows me the six harddisks on my D1000 but the local hard disk is not shown....& the booting process stops & doesnt proceed further.
# cd /dev/dsk
shiows the entries made on todays date....as i had given boot -r...i have also tried restoring from a backup taken 6 months back the effect being the same.
this server being an NIS client many users are being affected by it ..... any suggestions are welcome.
i will summarise
thanks n regards
