Re: File I/O Error

Hi,
Do you have an access to metalink?
This sort of error sometimes have a solution like apply a new patch vxfs kernel patch.
Look at the PHKL_39131 and his dependencies for 11.31 for example.
Hope it helps

Re: File I/O Error

There may be read erros in you filesystem or disk volume. Check with

cat > /dev/null

dd if=volume-for-your-file of=/dev/null (volume-for-your-file is the volume where /backup/arc/1_20402_631517123.dbf resides)

Check /var/adm/syslog/syslog.log for any errors relating to the filesystem/volume/disk

> cat > /dev/null

My cut-and-paste messed-up. It should be

cat /backup/arc/1_20402_631517123.dbf > /dev/null
