3-34 Troubleshooting
5. Process the memory dump:
A. Mount the first dump tape on the tape drive.
B. Log on as MGR.TELESUP,DAT.
C. Type DAT to initiate the Dump Analysis Tool (DAT) program.
D. Type GETDUMP xxxxx at the DAT program prompt, where xxxx is the 5 character dump identi-
fier name.
E. Reply to the tape I/O request at the system console.
F. When all tapes are read in, EXIT the DAT utility.
6. Call the Response Center and report the problem.
MPE/iX Memory Dump Detailed Procedures
To take a memory dump, perform the following procedure. Taking the wrong steps, or performing the steps
out of order can result in an invalid dump, lost data, and a waste of system processing time.
Step 1: Do a Transfer of Control (TC)
Initiate a Transfer of Control to change the CPU from its current state to the
ISL> prompt.The aim is to
preserve the current environment, so that data in the memory dump are valid.
1. Get into the Control Mode on the console. Type Control-B. The result should be the prompt for the
Access Port (AP) Control Mode:
CM>
2. At the
CM> prompt, enter TC and a single carriage return to execute a Transfer of Control (TOC).
3. To ensure that the TC took effect, watch the hex display located in the lower left hand corner of the
console when in CM mode. The hex display should change from the code it displayed prior to the TC
to a different series of codes (the series of codes displayed when the CPU undergoes selftest and the
system boots ISL.)
4. If the hex code DOES NOT change, the TC did not take effect. Try the following tactics:
A. Try typing a Control-M (no carriage return). If this produces no effect, do a hard reset of the termi-
nal and attempt another Control-B TC key sequence.
B. If the hex code still does not change, call the Response Center. The Response Center may be
able to help.
C. If all efforts to do a TC fail, you probably will have to do a Hard Reset. Perform a hard reset by
entering RS at the
CM> prompt.
