Physical Disk UnMark Hot Spare

Clears the hot-spare flag to un-mark the device as a usable spare in the event that a ZFS storage pool becomes degraded.

The purpose of "Unmark Universal Storage Pool Hot-Spare" in QuantaStor is to remove the designation of a drive as a hot spare within a Universal Storage Pool (USP).

A hot spare is a standby drive that automatically replaces a failed drive in a storage system, ensuring continued operation and data protection. When a drive fails within a storage pool, the hot spare is automatically used to rebuild the failed drive, minimizing downtime and maintaining data redundancy.

However, there may be situations where administrators need to remove a drive from its hot spare role. This could be because the drive is needed for other purposes, such as expanding the storage pool or replacing a failed drive in another pool.

By unmarking a drive as a hot spare, administrators can reclaim the drive for other tasks without it being automatically used as a replacement drive in case of a failure. This gives administrators more flexibility and control over the allocation of resources within the storage system.
