Backup ok, Restore fails (ANR0541W, ANR8555E, ANR1165E)

[blankgap]

TSM 7.1 running on Win Server2008 R2

Recently I added a few 1TB Volumes to my diskpool because I was in need of some "quick" storage. Those volumes come from 2 disks from another server and are mounted as network drives.
The backup on these volumes works just fine.
Now I have to restore some files from one of them, but the restore fails. Activity-Log shows:

10/14/2021 12:05:59 ANR8555E An error (64) occurred during a read operation

Any help would be appreciated.

from disk \\PCD00-IT-BAK-01\TSMMOUNT2\BACKUP27.DSM.

In the above error, (64) is a Windows return code, it means the following:

c:\Program Files\Tivoli\TSM\baclient>net helpmsg 64

The specified network name is no longer available.

Make sure you can access the path and try the restore again.
