Hello
I am in a process of migrating and old MSDP (Windows 2008R2, NBU 7.5.0.4) to a new one (same OS, same NBU version). I have installed the new server, created dedup storage and configured everything to integrate the existing infrastructure. I then started the image migration using bpduplicate. Evrything worked fine for about 20 hours and suddenly I got a lot of 2016 error codes "disk storage is down", I thought that I launched too many simultaneous bpduplicate processes, but even after everything finished (with errors !) I got the same problems. I had to restart the new MSDP server and since then , I can't even run a backup on this MSDP , I got 174, 811 and 2106 erros ...
I triple-checked all hostname resolutions on Master, old MSDP and new MSDP.
nbdevquery -listdv -stype PureDisk -U shows that the diskpool is DOWN, he sometimes comes UP and the down again ....
I have tried to clear all caches, restarted services on both master and MSDP
I also tried to install EEB 2975594.1 without any improvement ...
Any help will be appreciated ....
