Hi Jerry,
   I have some questions :
     * What VTL product are you using?
     * What kind of connection are you using?
     * Are you using BRMS? 
     * Have you tried to enable/disable the TAPMLBxx? 
     * Can you share the complete error message you get when trying to
       initialize the tape?
     * Are your virtual tape cartridges hosted on the VTL box or using an
       external Cloud Object Storage/Storage Account/Object Storage Device?
          * If so… can you connect manually to the remote repository?
     * Is your VTL showing any activity/connection/error message?
     * Can you try to create just 1 virtual tape cartridge in your VTL to
       check if it is working properly?
   I have seen something similar with Falconstor VTL when the connection to
   the Object Storage fails, and some cartridges show errors. In some cases
   we had to re-create the virtual tape cartridges showing error to fix the
   issue.

   Well, a good opportunity to test if everything works well after an outage.

   I don't know. But why do you use any density setting at all? Aside from
   formatting older QIC cartridges on newer drives, I've not seen any reason
   to not leave density at *devtype, and let the drive figure out what to do.
   Works provenly well for DDS1, 2 and 3 cartridges in DDS3 drives, LTO1
   tapes in LTO2 drives, and LTO3 tapes in LTO4 drives. Should not be any
   different for VTL.
   :wq! PoC
