ANR0454E Session rejected by server , reason: Authentication Failure

So somehow, the storage agent in one of the node of my HP-UX RAC clusters won’t start. Manually starting the storage agent reveal this error message :

“ANR0454E Session rejected by server , reason: Authentication Failure.”

So, that’s my problem. My TSM server refused to authenticate the storage agent. The first thing that I tried is to reinitialize the storage agent. Here is how:

1. go to your TSMSERVER console by typing

   dsmadmc

2. Update the password the corresponding node, the syntax is as follows :

   UPDATE SERVER <sta-name> SERVERPASSWORD=<sta-password>

   for example :

   tsm: TSMSERVER> UPDATE SERVER HQCMSDB1_AGENT  SERVERPASSWORD=myTSApassCMS

3. Reinitialize the storage agent, the syntax is :
   ./dsmsta setstorageserver myname=<sta-node-name> mypassword=<sta-node-pass> myhladdress=<sta-node-ip> servername=<tsm-server-name> serverpassword=<tsm-server-pass> hladdress=<tsm-server-ip> lladdress=1500
   for example :

   ./dsmsta setstorageserver myname=HQCMSDB1_AGENT mypassword=mySTApassCMS myhladdress=192.168.1.110 servername=TSMSERV serverpassword=TSMSERV hladdress=192.168.1.201 lladdress=1500

4. Start the storage agent again, see if you still get the error, if not, you’re done, otherwise, the problem might not be about the authentication. Check whether your node can reach the TSM server, and make sure that the appropriate port used by the agent to communicate is opened
