Removing disks from a disk enclosure and inserting them into another disk enclosure of the same model on an OceanStor V3 storage system

Except for coffer disks, disks can be removed from a disk enclosure and inserted into another disk enclosure of the same model on an OceanStor V3 storage system. Coffer disks are the first four disks of the first disk enclosure. In coffer disks, the system writes the serial number of the enclosure where coffer disks reside. Upon power-on, the system checks the serial number and denies access of the enclosure if serial number inconsistency is detected. Note that the disk to be removed and reinserted cannot carry data. The disk is recognized as a newly added disk on the disk enclosure where it is reinserted.
In addition, users are allowed to relocate a non-coffer storage pool member disk in a disk enclosure or across disk enclosures connected to the same engine. However, the interval cannot exceed two minutes between the removal and reinsertion. After the reinsertion, the storage pool automatically initiates a reconstruction, writing data that is supposed to be written during the absence of the reinserted disk.
