System hangs after converting hfs to Vxfs

[sacthivel.C]

Dear all,
We have one d380 server with HP-Unix 10.20.Recently we had a Hard disk Crash and we replaced the HDD.That time I created Vxfs file system instead of HFS(Previously the fstype is HFS).
After that The server gets hang once in a week and i didn't see any error on syslog and /etc/opt/resmon/log/client.log.It just responds to ping but it is not possible to contact the server either by telnet or ssh.I didn't get the console also.
The Hdd which i replaced is having Oracle 7.

Is this problem arises because of the FS Convertion? or some other.

pls help me.
Thanks in advance.

Is there any Error messages in syslog ?

Or

Is there any bottleneck condition ?

What kind of hang? oracle slow, system slow, or system frozen completely. Do you reboot or reset it? Introducing vxfs on HP-UX 10.20 while everything was working fine with hfs was a bad idea. It could be the vxfs that causes it, may be you are missing some vxfs patches. But for hp-ux 10.20, I would not touch anything, I would put back hfs on that oracle disk.

Dear All,
I didn't get any error message in syslog.I also put a script which records the output of top and sar for every 15 minutes.In that also i didn't see any process which occupies more space.
The system is frozen completely.We have to hard boot the system again to make it running.The only response i get when the server frozen is ping, noithing else.No telnet,No console and No database response.

Pls help me.

Dear All,

We finally upgraded the server to Linux.

So I am closing this thread.
