Which Commvault Jobs feed that log? I have some major events with the following message:
Error occurred in Disk Media, Path [/cvault/hua/nfs/XXX_02/dat/Y66R1O_08.08.2022_13.02/CV_MAGNETIC/V_648334] [Check whether the path [/cvault/hua/nfs/XXX_02/dat/Y66R1O_08.08.2022_13.02/CV_MAGNETIC/V_648334] is accessible.]. For more help, please call your vendor's support hotline.
I can do listing on that dir so, yes, the path is accessible.
