HPE ProLiant DL380 Gen10 server RHEL8

[Abeer1]

Hello,

I have two physical servers host RHEL8 lets name them (server1, server2).
Server1 has 4 physical disks configured on RAID1. The size of disk1 and disk2 together equal 800GB, and disk3 and disk4 equal 2TB.

Server2 has 2 physical disks configured on RAID1. The size of disk1 and disk2 together equal 800GB.

We need to remove two disks from server1 (which is 200TB) and then put them in server2.

First, I did lsblk to see is the disks that will be removed empty or not, it display sda,sdb,sdc,sde,sdf,sdg. why the total is 6 block devices? where I have only 4 hard drives?

anyways, I removed the two disks from server1 and put them to server2, after that I go to HPE iLO to remove the array that made of removed disks from server1 and to add new array to server2 with the new hard dive. The configuration for RAID in HPE ILO for both servers looks good.

but when I saved the changes and reboot the system the RHEL8 OS enter the emergency mode and there are a lot of logs related to the memory, something like mem [0009999999222222] reserved
mem [0333300000000] usable and more more of logs that I can't understand.

any one can guide me?

note: all thing is physical no vmware no virtual.
