Storage agent does not connect to Tivoli Storage Manager server

Answer

Two passwords must be provided when configuring a storage agent:

• The password of the storage agent itself
• The password of the Tivoli Storage Manager server it is meant to connect to.

If either password is incorrect, the storage agent will fail to connect.

The DSMSTA SETSTORAGESERVER command is used on the storage agent to configure the storage agent and specify the passwords. For example, if the storage agent name is MYSTA and the server name is TSMSERVER, the following command is used :

dsmsta setstorageserver myname=MYSTA mypassword=XXX myhladdress=<agentaddress> servername=TSMSERVER serverpassword=YYY hladdress=<serveraddress> lladdress=<port>


In the above command, XXX is the password of the storage agent and YYY is the password of the server. To determine if there is a problem with the passwords, try to start the storage agent in the foreground and watch for error messages.

To start the agent in the foreground on Windows :

c:\> cd c:\program files\tivoli\tsm\storageagent
c:\> dsmsta


To start the agent in the foreground on AIX :

# cd /usr/tivoli/tsm/StorageAgent/bin (V5)
# cd /opt/tivoli/tsm/StorageAgent/bin (V6)
# ./dsmsta


To start the agent in the foreground on Linux, HP-UX or Solaris :

# cd /opt/tivoli/tsm/StorageAgent/bin
# ./dsmsta


If the password of the storage agent (mypassword=XXX) is incorrect, the following messages are received when trying to start the storage agent in the foreground:


ANR4726I The ICC support module has been loaded.
ANR8200I TCP/IP driver ready for connection with clients on port 1500.
ANR0444W Protocol error on session 1 for node MYSTA (AIX-RS/6000) - out-of-sequence verb (type AuthResult) received.
ANR0454E Session rejected by server TSMSERVER, reason: Authentication Failure. ANR0454E Session rejected by server TSMSERVER, reason: Communication Failure. ANR3602E Unable to communicate with database server.

In this case, the password on the MYPASSWORD=XXX parameter of the DSMSTA command must match the password of the definition of the storage agent (as a server) on the Tivoli Storage Manager server. This is the password that was provided on the DEFINE SERVER MYSTA SERVERPASSWORD=XXX command. If the password in the storage agent definition needs to be updated, use the following command:

UPDATE SERVER MYSTA SERVERPASSWORD=XXX FORCESYNC=YES


If the password of the Tivoli Storage Manager server (serverpassword=YYY) is incorrect, the following messages are received when trying to start the storage agent in the foreground:


ANR4726I The ICC support module has been loaded.
ANR8200I TCP/IP driver ready for connection with clients on port 1500.
ANR0454E Session rejected by server TSMSERVER, reason: Authentication Failure. ANR0454E Session rejected by server TSMSERVER, reason: Internal Error.
ANR3602E Unable to communicate with database server.

In this case, the password on the SERVERPASSWORD=YYY parameter of the DSMSTA command must match the password of Tivoli Storage Manager server that the storage agent connects to. This is the password that was set on the server by using the SET SERVERPASSWORD command.
Use the DSMSTA SETSTORAGESERVER storage command with the correct server password.
If the server password is unknown or needs to be updated, use the following command on the server:

SET SERVERPASSWORD YYY

Note:
Use the SET SERVERPASSWORD command on the Tivoli Storage Manager server with caution. Changing the password will affect other storage agents, library clients, and server connections currently using the old password. If you change the password on the server, you must update the password for this server for all other storage agents and Tivoli Storage Manager servers that connect to the server.
