Operating SAT

1. First, be sure the system has failed.

2. Use the TC command to restart the failed or hung system through the access port. This preserves memory.

   Do not use the RS command -- it erases memory!

   NOTE: If SAT is not present on disk and must be booted from tape, ISL must first be booted from disk so that the MMSAVE utility has a chance to save main memory to disk. If this step is skipped, SAT is loaded into memory, overlaying the state of the machine.

   The following example shows what a user might see entering TC to transfer control, then CO to return to console mode.

To override, press any key within 10 seconds. 10 seconds expired -- proceeding with autoboot.

3. Invoke SAT from the ISL interface.The following output is a sample SAT session:

4. Analyze the failure. Most of the System Debug commands are available to you; restrictions are listed below. If you want to make a dump tape, return control to ISL with the EXIT command, then invoke the DUMP utility.

CAUTION: If you chose not to make a dump tape, but rather to restart your system, and the failure was ah HPMC. It is recommended that an RS command be executed prior to restarteng.
