We had to implemant a Dell EMC Unity to do NAS jobs.
The unity system is cut in 7 nas-server, which are independant of each other. I zoned the unity bay with the robotic library and LTO8 drives.
On NetBackup, when i detect the ndmp clients, the 7 nas-server appear well, with a dedicated STU.
I created 7 ndmp policies to dedicated each STU to each correspondant nas-server.
The backups are good.
But, when i would to restore some data of 3 nas in particulary, i have an error which is NDMP_IO_ERROR, cannot open ndmp device error 7. After, the path goes down and the restore job try an other path.
The others nas-server restore well the data.
I tried to read the bptm logs, but i see anything relevant.
Thanks for your help.

I saw that the issue spends when the job request a new tape after the 1st one is filled up.
When i try a robtest, i move the tape to drive successfully but when i move from the drive to the slot i receive the error move_medium failed sense key 0x5 asc 0x3a ascq 0x0, medium not present. When i do "unload d1" and "m d1 s139" everything is ok.
