System disk mirroring is the function that mirrors the system disk on which the running Linux operating system has been installed.
If a system disk failure occurs, the entire system probably stops and even booting will become impossible, and operating system reinstallation will be required. As a result, service stop may remain for a long time.
System disk mirroring ensures continuous system operation even when a failure occurs in part of the disks.
SAN Boot
In a SAN boot environment, system disk mirroring is not supported.
