Primary storage is deleted from UI but the LUN information still exists

[nexus]

Problem description:
The primary storage is deleted from the ui, the storage end is also unmapped, and after the platform synchronizes the san device, the lun information still exists.

Analysis of the cause of the problem:
The platform reads the lun information through multipath/lsblk
First, determine whether the physical machine at the bottom of the cluster can read the relevant information. It is found that although the mapping has been unmapped, there is still residual information on the physical machine in the cluster.

Problem handling process:
Check whether all physical machines in the cluster have unmapped related information read by multipath.
After the physical machine uses

rescan-scsi-bus.sh -r

to remove the relevant invalid information, there is no residual information in the multipath.
The UI synchronizes the san device information, and the lun information is removed.
