Configure disk access retries when booting a VM on IBM POWER

Solution Verified - Updated -


The GRUB boot loader retries accessing disks 20 times when disk access fails at boot. This causes problems if you perform a Live Partition Mobility (LPM) migration on an logical partition (lpar) virtual machine (VM) that connects to slow Storage Area Network (SAN) disks. As a consequence, the boot might take very long on the VM until the 20 retries finish.
