Everything was looking good until I tried pulling a disk drive from the RAID 1 pair while the system was running. I wanted to verify that it would continue on gracefully. What I got was a system that wasn't totally locked up, but it could not perform any disk access. I had a shell open on the console. Pressing enter would bring up a new prompt. Trying to do anything that required reading the disk would cause the shell to hang. I could go to another console window and get a login prompt, but as soon as I entered the login name, the login process would hang. If I power cycle the server, it comes back up OK and notes the failed disk. If I insert the disk while the system is running, it hangs in the same manner as when I removed the disk. If I reboot, the system rebuilds the disk and everything is OK. I tried this test a couple of times and got the same results. Sometimes the CISS driver would note the changes in syslog, but the system would still hang. I tried installing FreeBSD Release-4.9 and got identical results. I have a Dell server with PERC RAID running FreeBSD Release-5.1. I tried the same test on it and it performed flawlessly, logging the removal of the disk and the re-insertion without a single hiccup. Unfortunately, I need to get this to work on the HP Proliant hardware. Does anyone have any suggestions on how to get this to work reliably? If not, I will have to abandon FreeBSD and install some flavor of Linux on the servers instead. Thanks in advance. Paul Lutt Fluke Corporation paul.lutt@fluke.com
