HP rx 6600 server's power supply crushed and server was down. I don't know why redundant power supply didnt work.
We changed and now power supply works well. But after starting OS HP-UX 11.3i i saw some troubles in OS. There runs Oracle DB. So login and what to start some services such as lsnrctl and etc. But still can't find directory of Oracle HOME and others. What could happened with those directories? Did they delete during crush? when i typed
cd: /u01/app/oracle/product/10.2.0/db_1:
i got error message: No such file or directory
why and what happened, who could give advice?
Regards,
Rustam.
Solved! Go to Solution.

Can you check does mount point mounted
bdf -> output
or
bdf /u01/app/oracle/product/10.2.0
Check below logs & commands, to identify any disk failure
dmesg
/var/adm/syslog/OLD.syslog.log
/var/adm/syslog/syslog.log
/var/opt/resmon/logs
vgdisplay -v |more -> look for any "Psyical volume problem"
Thanks,
Johnson

Re: i don't know what happned?rx 6600 server's power supply crushed
Seems some of the filesystems are not mounted ,
Check the mounted filessytem with bdf and compare it with /etc/fstab
check whether all vgs are in active state (vgdisplay)
analyze /etc/rc.log for startup messages

Except missing file system or file system curruption there does not seesm to be any cause.

Re: i don't know what happned?rx 6600 server's power supply crushed
you might be having redundant power supply,but during some time this may happen ,, most commonly it might be having two UPS power.
when one source get fails,redundant gets on ,but sometimes it cant bear the power and redundant also get fails ..
so check with the logs as said by Johnson.
login to console and check with ps so that you can have clear idea abt that.
nothing to fear abt it,,,
check with bdf and /etc/fstab.
may be that file system may not be mounted.
note:::: perform a periodic power testing activity ( may be in every quarter)
log a call with backend team and check the status of the system...

Re: i don't know what happned?rx 6600 server's power supply crushed
Now server works normal but i think i have to read about file system and mounting of them. Coz i didnt\dont know anything about file system of HP-UX and /etc/fstab and what to add there.

Rustam

Re: i don't know what happned?rx 6600 server's power supply crushed
Well just in case....if u have cluster things would be entirely different.
else just same entries as the last in /etc/fstab
except the mount point and block device would change.
Anyways I suppose you would be having entries already as this was just because of EVA problem.

Re: i don't know what happned?rx 6600 server's power supply crushed
Kapil Jha, yeah, i think, it wasn't due of EVA problem. These days i'm reading about file system, and it's really different then MS. I have a lot question about file systems but i hope\think that man pages + google could be good teachers for me :)
