here is what happened :

* We had  – HP Integrity rx2620  server with Linux Enterprise Workstation installed on it.

Server had a 3 internal disk and attached RAID storage . Monitor , keyboard and mouse were attached to server

* Application owner tried to reboot machine and then called us saying machine never came up

* We find out one of disks on external storage is dead (for clarity , there was not any mirroring or parity )

* Found out that , when machine “hangs” after initrd  message . Waited 15-20 minutes , tried ping from remote machine , no answer

* turned off and turned on machine again and opened “boot configuration ” menu .

opened EFI shell and ran conconfig (console configuration ). It showed that , VGA was as a secondary console . made it primary and rebooted machine .

This time i got all output to the monitor and system came to single-user mode because of failed disk (could not mount file system ) . Removed entry from /etc/fstab and then rebooted machine.

Everything came up fine (except of course , failed file system)
