Explanation of some names involved in RAID card configuration
Disk Group: Disk group, which is equivalent to an array here. For example, if a Raid 1 is configured, it is a disk group;
VD (virtual Disk): virtual disk, the virtual disk can not use the full capacity of the array, that is to say, one can be divided into multiple VDs;
PD (physical disk): As the name suggests, the main is the physical hard disk;
HS: Hot Spare, hot spare disk

Let me say more here:
I installed centos 7/red hat e..... 7 These two versions have an error here, the error message: no default or UI ..., the installation said on the Internet, I have tried many times and many methods and can't solve it
After installing centos 6.5, after partitioning, it has been [retrying the download]. It is said on the Internet that because the mount point of the u disk is [/dev/sda], this can only be reinstalled.
After tossing for two days, because I had no problem with the previous installation, I suspected that there was a problem with my USB flash drive, and I replaced it with a USB flash drive.
- 3. All the way [next] even if it is done
3 points to note:
When partitioning, be sure to look carefully at which hard drive is being divided
Password can't be too simple
Minimal installation of software.
