These The MegaRAID SAS controllers re called Percraid on Dell Poweredge servers. They use the MegaCLI utility, which is described here.

MegaCLI

This to show what virtual disks are present. This describes a system with a pair of 300GB SAS 15k rpm disks holding the OS, an array of four 1TB drives and a pair modern 20TB drives, forming a 300GB OS drive, a 20TB data drive and a 3TB additional storage drive. Below are the virtual drives:

One of the 300GB SAS drives (for the OS) is reporting a SMART error. This disk should be replaced before it fails.

Disk swap

This is where the disk is swapped over. Once the new disk is inserted it rebuilds itself.
