I am running RHEL 6.x in my production and booting from local disk which is actually RAID 1 configured from BIOS. (IBM Blade Center H)
I wish to migrate this to SAN disk and perform SAN booting.
This Post in a way resembles to my problem.
I have /boot and /boot/efi as partition and rest of remaining space allocated to vg-lvm and OS FS is mapped.
/boot and /boot/efi is of size 1 GB each.
I am planning to clone /boot and /boot/efi on san disk with dd command.
May be I need to install grub on SAN disk as well.
and then I will perform pvmove and migrate OS FS on to SAN disk.
Is this the correct way to migrate OS disk to another ? Let's assume this is just DISK to DISK migration where the size of disk is different and exclude the SAN part.
