NDMP media write error(84) while writting to Data Domain
Hello,
Hardware/software info:
Netbackup Server Linux Redhat using Netbackup version 7.7.3 (master as media)
Client: os version "NetApp Release 8.2.4P6 7-Mode"
DD6300 OS 6.0.1.10-561375
It is my first post so please forgive me mistakes. I have an issue with NDMP backup. The problem occures only with montlhy schedule wchich is using accelerator forced rescan option. It was working properly long time and a few days ago strated to fail with error code 84 media write error. It starts to write data and after some time fails. The backups goes directly to DD via DDboost.
I do not have an access into client so I need to focuse on master server.
anyone has faced similar issue?
