• To check the guest OS status before collecting a dump, before collecting
the guest OS dump, collect console log data and capture a logical VGA
snapshot.
You could not be too careful when collecting dumps because that
collecting dumps may damage the guest OS.
What is Console log data?
Console log data is the screen data displayed when the guest OS on an LPAR
is running. LPAR manager stores especially 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.
How to collect console log data
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 sub-screen. Use the up and
down arrow keys to select 'Yes' on the sub-screen, 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 may not be included in the console log.
How to delete console log data
Place the cursor on the CLE column in the LPAR row whose console log data
you want to delete. Press [Enter] to display a sub-screen. Use the up and
down arrow keys to select 'Yes' on the sub-screen and press [Enter].
This will delete the LPAR's console log data from the buffer in LPAR manager.
How to recover Migration Failed LPAR
Recover an LPAR with Migration Failed, if any. See the Hitachi Compute Blade
HVM Navigator User's Guide - Migration for the procedure of recovery
operation.
