Live Kernel Update Must Gather

Technote (FAQ)


What data needs to be gathered for issues with LKU, (Live Kernel Update)?


On the AIX 7.2 system that we ran the LKU on, clean up any previous snaps.
#snap -r
#cd /tmp/ibmsupt
#rm *.pax.Z

Run "snap -a".

Copy the liveupdate directory to the testcase folder.
#cd /tmp/ibmsupt/testcase
#cp /var/adm/ras/hmcauth.log .
#cp -r /var/adm/ras/liveupdate .
#cp -r /etc/liveupdate .

Compress the snap using the "snap -c" command.

Submit that snap to ECUREP.
