IO Error

hmorrison — Thu, 13 Jul 2006 17:33:28 GMT

On HP Server running HPUX 10.20, I tried to mount a couple of file systems and got the following error, vxfs mount: cannot mount /dev/vgfc60/lvcis46
vxfs mount: I/O error
I tried to run a fsck /dev/vgfc60/lvcis46 but I got the following error; cannot open device /dev/vgfc60/lvcis46
Can someone help please? Thanks!

Post these outputs:

vgdisplay -v /dev/vgfc60

ls -l /dev/vgfc60

lvdisplay /dev/vgfc60/lvcis46

could be something wrong with your PV located on fc60. try running dd on it:

# dd if=/dev/vgfc60/lvcis46 of=/dev/null bs=64k count=10

I/O error means there is a hardware problem, fsck can't fix any hardware problems as you have seen. Look is /var/adm/syslog/syslog.log and you should see lots of errors. Use the dd command to check all the physical disks in vgfc60
