Follow these steps to use SAT:
First, be sure the system has failed. 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. | | | |  | TIP:
CM>TC Transfer Control
CM>CO Return to Console mode

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.
