Eugene,
Thanks so much for your help!
The systems are brand new. I'm currently working with 5 but eventually have to get nearly 80 up and running. They're operating in a dusty desert environment, obviously not the best place for any computer system, but we have many other servers operating in the same environment without a high rate of disk failure.
I didn't find any indication yet as to what is causing the 'broken' and 'failed' notifications on the drives, but two of them seem to be back up. They're currently operating in the 0 and 13 slots. The one in slot 0 seemed to recover on its own as its status changed from failed to 'dparity reconstructing' before I really did anything other than halt and boot. I used disk unfail on the other and now it's status is normal as well. This is good news because I was beginning to worry about being able to keep enough spares on hand if drives were to continue failing at such a high rate.
I'm not really sure where to find the syslog messages you mentioned, other than the reports in the filerviews which don't reveal much information.
Thanks again,
Greg
