MSDP Storage server config error (99)
MSDP Storage server config error – credentials already exist (99)
go the media server on which you encounter the issue and run below commands
tpconfig command is located in volmgr\bin folder
tpconfig -dsh -all_hosts”
to find the User ID that I had configured for the storage server.
I then use
“tpconfig -delete -storage_server <servername> -stype <StorageType> -sts_user_id <userid>
Now start the MSDP configuration to proceed.
