Hi

Looks like HW problem coming up .

Look at ls -1 /root

If that works you have corruption or a file name with a space or something in it in the root directory

try

cd /root
ls -1|while read line
do
echo $line
ll -d $line
done

If it hangs the last line printed is the problem.

An HArdware failure can be any of the disks in VG3 or the SCSI channel which consists VG3 is going to fail.What is look in #ioscan -fnC disk

do u have any EMS configured,check if available

An NFS (remotely mounted) filesystem can cause ls and bdf to hang. Check for a networking problem here.

The syslog messages indicate a problem with the 3 disks in volume group 3:
device 0x1f040200
device 0x1f040300
dev_t=0x1f040100

To determine the devices:
# ll /dev/dsk |grep 040?00

If these disks are in a cabinet, check cabling and power. It might be as simple as that.

# ioscan -fnC disk
Look for NO_HW or completely missing disks. (This is a hardware problem.)
# diskinfo -v /dev/rdsk/cXtXdX
Look for problems. (This is a hardware problem.)

If there are no SCSI lbolt messages, this is probably not a hardware fault, but you may only need to increase the timeout.

Check the timeout with pvdisplay. If it says default, increase it with:
# pvchange -t 180 /dev/dsk/cXtXdX

Watch for further errors. If they continue or if there are other SCSI errors, then contact Hardware Support.

Dear All,
The following error found. Its VA7110 having two controllers. itseems one controller is not working/faulty. But as its configured as RAID 0+1. I should be able to work with the volumes created on it. Here I ma not able to connect to the volumes. So far I have not restarted my server. The HDD in array showing all green lights which means there should not be any prob. with the HDDs.The o/p of ioscan is this...

You can try:

ioscan -fuC disk
insf -C disk

Dear All,

Thanks for the response. The problem is resolved.
I had to restart the Array and the server.
So its got connected to that Controller, may be some link failure was there.

Rgds
