BDF command stucking

[Deeos]

hi ,

can any one tell me!
why bdf command not responding
I mean, what valid reason behind of it in genrel cases.

[Vijaykumar_1]

NFS filesystems not getting mounted..

Do you have NFS filesystems on the server ?

[Pete Randall]

As pointed out, it's most likely NFS mount points. Try running "bdf -l", just listing local file systems.

bdf -l output is coming

there is no nfs environment!

[V. Nyga]

Hi,

can you give us the content of /etc/fstab
and your bdf -l output?

V.

[Deeos]

can it problems of storage mount point itself?

[Suraj K Sankari]

Hi,
2 3 things need to be check
1.Check is ther any NFS file system is there?
2.because of disk may be bad ?
3.check the disk/cpu/memory usages it may vary high.

deeos,
Check if # bdf -l # command is getting through.
Most likely you have NFS issue. In that case you have to reboot(most likely) to fix the problem.

Also check:
# ps -ef | grep bdf | grep -v grep
To see since when bdf is hanging and the hung sessions.


hth,
Raj.

Since you did not supply the model of your system or the version of HP-UX, I'll have to give things that may not work because you have an older system. Start with:

bdf -s

If this completes immediately, the one or more of the mountpoints is extremely busy changing information in the mountpoint directories. Or there are disk errors being recorded in syslog.

If this is not a valid option, then try each mountpoint in fstab like this:

bdf /stand
bdf /
bdf /tmp
bdf /var
bdf /usr
bdf /home

and so on. Most should complete immediately so the one (or ones?) that is hung is the problem.

Also run sar -d 2 4

to look at disk response times. Do you have both internal disks and external fibre disks? If fibre, are they part of a larger SAN switch? And finally, did the problem just start or has bdf been stuck for a long time.

now , bdf is coming
