I/O Error

[brian_31]

when the oracle team tries to add a datafile they get this error

When we try to add a datafile we get the error as HP-UX error : 5: I/O error. any ideas?

this is the exact error..
ORA-19502: write error on file "/oracle/data/clud_35/clud.data35", blockno 6401 (blocksize=8192)
ORA-27072: skgfdisp: I/O error
HP-UX Error: 5: I/O error
Additional information: 6401
(2007-01-01 01.08.19)

please advise

Thanks

Errno 5 indicates an EIO. If you do a man 2
write, you will see that the write system call sets errno = 5 on a physical i/o error. This means that an i/o error occurred at the hardware level so check for a bad disk, cable, etc.

Check the syslog.log file as well for errors. The disk on which you are trying to create the datafile maybe bad alongwith other ones. syslog.log would tell you which disk devices are having I/O problems.

now when i try to extend the filesystem i get this error.

vgcfgbackup:/etc/lvmtab is out of date with the running kernel: kernel indicates 12 disks for "/dev/data10";/etc/lvmtab has 11 disks. cannot proceed with the backup

are these related errors?

thanks

Hi,

did you replace a disk already?

This message indicates very often a wrong replacement procedure.

What can you find out about the device mounted on /oracle/data/clud_35 ?

Does an lvdisplay -v of the lvol show anything fishy ? Also try diskinfo -v on the physical volumes.
