Problem Description:
Unable to decommission 5220 Appliance Medias server using nbdecommission command.
Nbdecommission tool indicates that this server is part for some media sharing group, and nbdecommission completes with error “unable to delete host xyz_abc”.
nbdecommission -oldserver xyz_abc
Server xyz_abc is a member of the following media sharing groups:
UNRESTRICTED_SHARING_GROUP
netbackup emm database error 196
Unable to delete host xyz_abc
# nbemmcmd -deletehost -machinename xyz_abc -machinetype media
NBEMMCMD, Version:7.5.0.6
The function returned the following failure status:
generic EMM SQL error (193)
Command did not complete successfully.
Solution:
From Netbackup console:
Even after above cleanup activity, we still see the same error. Using “NBSU” and “nbdb –unload”, it was identified that one storage unit has options selected to use only listed media server, howeverno media server from the list is selected. So such undefined entry will hold all configured media server and will not allow you to decommission any media server from the environment.
I selected a specific media server for this storage unit and then ran “nbdecommission –oldserver xyz_abc”, it completed successfully.
