Hi, I have the following: IBM eSeries x345 server 6 x 10K rpm Ultra 160 SCSI 36.4 GB drives (hotswappable) RAID 5 is installed with 5.10 ServeRAID version RedHat 8, with all of the latest RPM updates For some reason, after the server has been running for a period of time I get the following errors in /var/log/messages: Jul 20 04:22:00 <hostname> kernel: I/O error: dev 08:03, sector 67976 Jul 20 04:22:00 <hostname> kernel: SCSI disk error : host 0 channel 0 id 0 lun 0 return code = 70000 This error happens over and over with a different sector each time. All IBM diagnostics report no physical or configuration errors. The server continues to function, however, the response time of it is What I have tried: Restoring all disks to factory-defaults, rebuilding the RAID, reinstalling the OS. The problem returns again after the server has been up and running for a period. ****I have dozens of these machines with the same configuration. I can't duplicate the error...yet. I have 2 or 3 machines that have this problem, but not all of my machines. Anybody seen these errors? Thanks for any help.
