Me and many other technicians hate the limitation that the only supported way of migrating the Loadsource disk to a smaller LUN is save/restore IBMi OS. With the method described below, I was able to copy the Loadsource to the smaller disk, and it worked. Continue reading “IBMi – copy the loadsource to a smaller disk”

Administrative Domains on IBMi – PowerHA
I would like to share my experience from implementing and configuring the feature of PowerHA – The Administrative Domains.

Back in the day, downloading of a server firmware from IBM Fix Central website was limited only to users and serial numbers with valid IBM hardware maintenance contract. With POWER8 servers IBM put such a lock into the servers. Thus, if your hardware maintenance contract expired, you cannot install any newer firmware beyond this date.
