Re: frecover checksum errors
Hi
frecover is experiencing intermittant I/O problems while running.
Percentage wise it will be hardware.
Check the syslog.log for errors
Check also
1)Latest scsi/tap epatches
2)Can you read any other backups .
3)Is there a heavy process on the same bus at the time of the frecover which could be a problem.
