The Centos server could not find the system disk

One busy morning, I suddenly received a picture from the maintenance staff:

The first thought of the system disk disk is broken, check after normal

Then it comes to the problem of RAID, after entering RAID:

Two system disks become foreign

After confirming that no one has touched the disk, import the two system disks again

Press F2 at the top, then foreign config and then import

Choose YES

Dengdengdeng! ~~~ The repair is complete
