Inquiry about disk device name?

When configuring the same server, there are times when the disk configuration in several servers is not named sda, but starts from sdb. Is this a problem when something happens?

    Thanks for the reply.

    We've been building RHEL, and we're building 20 or so.

    There are 5 disks, but slots 0 and 1 with the same capacity are configured as RAID1, and the rest are not in use yet.

    During installation and configuration on the two servers, the disk sda is not visible and the output is from sdb. I think I've had this happen before, but I couldn't solve it.

    For what reason?

    Hi @GIZGIZ,

     

    Usually it happens when the RAID container is not fully detected before other drives are detected. From the lsblk output, are all the drives detected?
