Vblockio Read Error

[Angela Shepherd]

I have a L Class 2000 running HP-UX11 (SUPRA Database Application).

One of my databases crashed with a vblockio: read_error! error = 5
vblockio: devno is 4

/dev/vg01/lvol1 file system file data read error.

Is there something I can run to help pin point this problem.

Well as 1st steps:
..identify what disks spaned by /dev/vg01/lvol1
# lvdisplay -v /dev/vg01/lvol1 |more
.. "ioscan fnC disk " should show all disk CLAIMED
.. run "diskinfo /dev/rdsk/cXtYdZ" on each disk
see see if factory info is correct & of course size different than 0
.. check syslog for LBOLT, scsi time-out, bus resets & dev_T messages
.. to validate disk sanity run dd against it as:
# dd if=/dev/rdsk/cXtYdZ of=/dev/null bs=blocksize count=n (Copy only n input blocks)
.. dd should return equal INs & Outs
g'd luck
