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.

Re: BDF command stucking
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.

Re: BDF command stucking
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.
