(1) How to check LPAR system status
Display the Front Panel screen.
Check the remark displayed in the Liquid Crystal Display column in the LPAR row
whose system status you want to check.
(2) How to collect guest OS dump
Display the Front Panel screen.
Place the cursor on the Dump column in the LPAR row whose dump you want to
collect. Press Enter to display the subscreen to execute a dump. Place the cursor
on Yes and press Enter. A subscreen that re-confirms the dump execution will be
displayed. Place the cursor on Yes again and press Enter.
Dump collection is possible only when the relevant LPAR is activated.
With this operation, an INIT interrupt is issued to the LPAR for the IPF version LPAR
manager and NMI is issued to the LPAR for the Xeon version LPAR manager to
obtain the memory dump of the guest OS.
You could not be too careful when collecting dumps because that collecting dumps
might damage the guest OS.
(3) What is Console log data?
Console log data is the screen data displayed when the guest OS on a LPAR is
running. LPAR manager stores character data among the screen data in the
internal buffer (up to 1,500 lines). If the console log data exceeds the number of
lines in the buffer, it is overwritten sequentially from the oldest data.
(4) How to collect console log data
Display the Front Panel screen.
Place the cursor on the CLD column in the LPAR row whose console log data you
would like to display. Press Enter to open a subscreen. Use the arrow keys ([↑] or
[↓]) to select Yes on the subscreen, and press Enter.
It will take two to three minutes for the log to be completely displayed on the
terminal screen. During the period, you will be unable to perform operations on
LPAR manager.
With displaying console log data on the screen by this operation, you can collect
and/or view the complete guest screen data as the Tera Term scroll buffer data.
If the LPAR's guest screen is updated while the console log is being displayed, such
new content might not be included in the console log.
(5) How to delete console log data
Display the Front Panel screen. Place the cursor on the CLE column in the LPAR
row whose console log data you want to delete. Press Enter to display a subscreen.
Use the arrow keys ([↑] or [↓]) to select Yes on the subscreen and press Enter.
This will delete the LPAR's console log data from the buffer in LPAR manager.
(6) How to recover migration failed LPAR
Recover an LPAR with Migration Failed, if any. For the recovery procedure, see
HVM Navigator User's Guide Migration Functions.
