I have an IBM Eserver running Red Hat Linux ES v3 i686. This server is primary a web server and was running fine for years until recently when a user called to ask if there was something wrong the the server. When I checked the console the server appeared to be completely hung, after restarting I received this message from the IBM ServerRaid manager - blocked logical drive hit F4 to continue or F5 to make no changes. I hit F4 and the system comes up with no problems. I contacted IBM and downloaded all the latest and greatest drivers for the hard drives, the raid controller, Linux drivers, even the system bios. This seemed to solve the problem at least for awhile but it has come back again. I have used fsck to check all the partitions for bad blocks, but his does help either.
A recent example: I used Linux update to install some updated rpms on the system - they downloaded and installed correctly when I went to click finish - all the drives in the raid 5 array pegged on a solid green and the system hung - upon reboot - the blocked logical driver message again.
Any help - this one is driving me insane.
