Unable to delete tape library. error 196.

Hi All,

i encounter network read failed when i was trying to perform backup. 

since this only happen to one of my media agent. ( i got 2 media agent, 1 is EMM server that is attach to MSL01, another is media agent server attach t MSL02), i suspected the issue is with my connection.

since ping and rdp didnt find any issue, i decided to delete MSL02 and read it back to EMM server.

unfortunaly i encounter with below error. 

 

as suggested by the forum, i edited the registry and remove all other media server except for master server.

after reboot, ebemmcmd -getemmserver still showing media server

i still cant delete the media library and VTL attach to this library also not able to communicated to EMM server.

can someone advice how should i proceed? i just wanna delete this tape library and readd the tape library.

media library are free to be rebooted. im open for any suggestion

 

Regards,

Me

  • When I've had issues with devices not being able to be removed, I generaly find that the following command, will allow you to removed them...  (with the options below it will remove ALL devices, so if there is more libraries / drives configured you  will need to recreate all of them again....)
    nbemmcmd -deletealldevices -allrecords

    You can also look to delete devices for a specific machine too....

    Usage:
    nbemmcmd -deletealldevices [-allrecords] [-emmname <string>] [-emmport <unsigned integer>]
    [-machinename <string>]
    [-machinetype <api | app_cluster | app_server | appliance | client | cloudpoint_server | cluster | disk_array | foreign_media | master | media | nbwss_endpoint | ndmp | remote_master | replication_host | virtual_machine>]

  • Is it possible to nbdecommission the media server with -newserver switch and reintroduce it?

    I must admit I only work with OST devices and not tape libraries. But something is referencing an EMM server that isn't accesible. I see the case sensitivity is different between the master and media, which may or may not be messing with NBU.
