From a window on any other machine, issue the following commands:

• telnet waimea and when prompted log in as teloper
• /etc/oareboot

Now wait. waimea takes about a couple of minutes to reboot normally. If you are rebooting following a crash, it may take twice as long or more, as it will have to boot once, run fsck and then boot again.

• When waimea is back up, before restarting any NIRSPEC software, have the swing tech or OA on the summit cycle power on the SCSI-Fiber extender box connected to the NIRSPEC host computer waimea. This box is in the Keck 2 computer room, in the rack where waimea, probably sitting on top of or next to waimea itself. This box is labelled "NIRSPEC TRANSPUTER" on its side. There are several such boxes in this rack, so the summit personnel needs to be sure to check the label when cycling power. The power switch for this box is a rocker switch on the back end. HANDLE THIS BOX CAREFULLY! THE SCSI CONNECTOR ON THE BACK IS NOT STRAIN-RELIEVED!

The next, more invasive, level of troubleshooting is a console reboot. This should be attempted only if the OA reboot described above has failed. To perform a console reboot, the swing tech or OA on the summit must go into the K2 computer room and connect the "roving" monitor (probably located on a small cart near the computer rack) to the video output on the host computer waimea. The summit person must then locate the keyboard attached to waimea and issue the following commands:

• stop-a
• sync

and the computer should reboot itself automatically after that.

Hard reboots are accomplished by having the swing tech or OA on the summit shut off power on the host computer waimea itself, wait 30 seconds, and then restart power. Do this only as a last resort! If at all possible, call the on-call software support person for advice before proceeding with a hard reboot. Ask if there are any other ways to reboot without cycling power, and ask also if there are any precautions that should be taken before hard-booting if it is necessary.

After the boot is complete and the server is restarted, in any window with a waimea prompt, issue the following commands:

1. m test2=1
2. cp /tmp/TEMPFITS2 /tmp/TEMPSKY2

The first command takes a test SCAM frame, and the second command copies it to the file that the guider camera server looks for to do the "sky" subtraction. If this file /tmp/TEMPSKY2 is not present, the camera server will fault and possibly crash.

Every reboot wipes the /tmp directory clean, so it is necessary to do this immediately after a reboot to enable SCAM guiding to work.
