I have now seen this particular behavior on my system three times.
This is an Alphaserver 2100A (recently acquired).
I am trying to run the sys_check utility on it. It
is currently sitting hung, trying to do the command
scu scan edt bus 3
as part of the sys_check. The ps output looks like this:
1335 console IW + 0:00.03 /usr/sbin/getty console console vt100
2248 ttyp1 U N 0:00.02 scu scan edt bus 3
2353 ttyp1 R + 0:00.02 ps
8265 ttyp1 I N 0:01.14 ksh -p /usr/sbin/sys_check - scsi none 33
-
31051 ttyp1 S 0:00.51 -csh (csh)
31233 ttyp1 I N 0:10.18 ksh -p /usr/sbin/sys_check
Bus 3 is otherwise quite functional. The drives on it
can each be accessed quite well. But the scu scan edt bus 3
will continue to keep going and going until such time
as the machine will be rebooted (which will be tomorrow). Eventually
if the process is left uncleared, other I/O also starts to hang,
forcing the machine to be rebooted.
I am running 4.0g with all the latest firmware and patches.
