OS Disk name is not consistent with multiple local storage array controllers B120i B420i Driver Ordering
Issue
We have installed the OS on B120 Raid and it detected OS disk name as /dev/sda but after we created the additional logical drives on B420i raid for our data storage the OS disk name changed to the last available disk name (ie /dev/sdp).
This causes grub to fail to boot.
Please advise on this for creating the persistent disk name.
