bad hard disk on sunfire x2100 running cent os x64?

I am having issues with a new server and just wanted to verify the problem is with the hard disk.

It is a Sun Microsystems SunFire x2100. It is running Cent OS x64. It has two 500 GB SATA-II hard disks.

The problem I get is that after a while, nothing responds. I attempt to shut down, and it spews a bunch of errors saying that the file system is in read only mode.

Upon reboot, I get messages such as:

buffer i/o error on device dm-0 logical block 0
command 0xca, timeout stat 0xd0 host stat 0x21
ATA 1 translated ata stat/err 0x51/84 to scsi sk/asc/ascq 0x6/47

I reboot and it'll work fine again for a while. I have removed the drives and plugged them back in and it doesn't seem to do anything. Am I correct in assuming I have a bad hard disk? or is it something else?

thanks

Do you see any errors in /var/log/messages that might related to the issue?

You can also always run badblocks on the disk. A destructive test would be best. Be aware that that will destroy all data on the device. You would run badblocks from a bootcd or something.

badblocks -svw /dev/<device name like sda>

you can add a
-p <number>
to specify a number of passes.

Oh there are always the tools from the manufactorer too. Perhaps you can run them from the ultimate bootcd, not sure if it supports SATA. www.ultimatebootcd.com
