Performing a Domain Memory Dump
The
Dump
command is used when the Operating System hangs and allows technicians to
diagnose software problems by saving domain memory.
Warning:
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:
1. Click
Domain Manager
to open the Control pane.
2. Select the required domain. If
RUNNING
is displayed in the
Domain Status
panel, the
Dump
button is accessible.
3. Click
Dump
to override the Operating System and forcibly clear domain core memory
which will be copied to the PAP unit hard disk for analysis. The
Dump Confirmation
dialog opens.
4. 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).
As the dump sequence progresses, dump steps and domain state are displayed in the
Domain Status
panel, as shown in the following table.
Dump States
POWERING ON
POWERED ON – LOADING BIOS
BIOS READY – STARTING EFI
EFI STARTED – BOOTING OS
RUNNING
Table 13.
Dump states
Once the
Dump
sequence has been successfully completed,
RUNNING
is displayed in
the
Domain Status
panel and the
Power Off
,
Reset
and
Force Power Off
buttons
become accessible.
5. Repeat Steps 2 to 4 for each domain on which you want to perform a memory dump.
Note:
If an error message is displayed in the
Domain Status
panel, the
Dump
sequence has
failed. See
