After flashdisk replacements, duplicate entries for flashdisks are still present after months. Duplicate entries has appeared in MS files after the replacement moment. They have never been cleaned after 7
days as expected.
There are duplicate entries for the same lun name "1_0". Status for one of them is normal but the other is not present. Those normally can be ignored when disks with status "not present". After a device
replacement, old entry is kept for another 7 days. This is known as expected behaviour.
The reason for unknown / not present state is that there are two entries for each phsyical disk. This is a known issue that has been fixed in 184.108.40.206. Old entries are kept for diagnostic purposes for 7-days.
