MiniDAQ Reboot
Once the Table Server and State Manager are running, a MiniDAQ reboot
is the fastest way to set up and connect the 5 MiniDAQ processors:
-
Click on the MiniDAQ desktop to watch the MiniDAQ
processor windows (assuming you've telnet'ed into the processors).
-
Locate the leftmost (MVME-167) module in the MiniDAQ VME crate
(scaup), and push the red RESET button.
-
Rarely, a simple reset is not enough, and VME-crate power-cycling is
needed for full re-initialization. (There's always a small risk of
hardware failure, so don't do this first.) Power off the
crate with the rocker switch, wait 20-30 seconds, and turn it back on.
Rapid flipping may blow the VME power supply and/or fail to reset the
modules--give it time.
-
Within a couple of minutes, prompts should come up on all 5 processor
windows. Occasionally, one may have to break and re-establish the telnet
connections.
-
If not, try another reset. Booting can fail from timeouts, if the
network is busy, or processor synchronization problems.
-
If the processors still don't boot, the problem might be with the
setup on deneb or the VME processors; find an expert.
Expected "Error" Messages
Both scaup and eider produce "error" messages
during a boot; messages like the following should be ignored:
-
IO system set up.
usrScsiConfig: scsiPhysDevCreate failed.
-
task: 0X787430 tShell
Missing driver support entry table : drvDummy
0x787430 (tShell): iocInit: Drivers Failed during Initialization
-
Failed to set time from Unix server
0x787430 (tShell): iocInit: All initialization complete
value = 0 = 0x0
