Managing Domains
Performing a Domain Memory Dump
The Dump command is used when the Operating System hangs and allows technicians to
diagnose software problems.
CAUTION:
The Dump command should only be used if the Operating System is not able to
respond to a standard Power OFF command. The Dump command may result in
domain data loss and file corruption.
The Dump command does not power down domain hardware (automatic warm
reboot).
To perform a domain memory Dump from the PAM Domain Manager:
1. Click Domain Manager to open the Control pane. If RUNNING is displayed in the
Domain Status panel, the Dump button is accessible.
2. Click Dump to override the Operating System and forcibly clear server core memory
which will be copied to the PAP unit hard disk for analysis. The Dump dialog box
appears.
3. Click Yes to confirm the Dump command. The Dump sequence results in a warm reboot
of the domain BIOS, EFI and Operating System without closing running applications and
saving data.
For guidance, the following table indicates the five dump steps and corresponding
domain states.

Once the Dump sequence has been successfully completed, RUNNING is displayed in
the Domain Status panel.
Note:
If an error message is displayed in the Domain Status panel, the Dump sequence has
failed. See What To Do if an Incident Occurs, on page 3-11.
