erros with raid5 dell poweredge

[Stefan Miklosovic]

hi list,

today after some work on server, it froze and
because I live 50 km far away that server, my buddy has
assisted in recovery.

After rebooting, he took some photos and
wrote me, what he saw / did.

Before resetting of server, these messages have been
appearing on screen:

aac0: COMMAND 0xc77..... (that part changes) TIMEOUT AFTER 2280 SECOND
aac0: WARNING! Controller is no longer running! code=0x1000080

there was an unresponsive login dialog, after typing login name, no password
prompt has appeard.

After reseting server by power button and rebooting, before freebsd boot
dialog,
this message surprised my buddy:
Container#0 - RAID5  203GB Critical
1 Container found
Bios installed succesfully

After that, server normally booted and is up now.
