Hello,
My problem is the following: Archive backups from a node has a very high failure rate (like %60). Usually one session cannot mount a tape, and freezes in state of MountW, blocking the next backup sessions. When I log in to the server, kill dsmsta and backup processes, the next archive is taken without problems, but then the problem repeats itself.
Here is the dsmerror.log from a server, this error happening all over:
03/25/08 16:47:20 ANS5216E Could not establish a TCP/IP connection with address '127.0.0.1:1500'.
The TCP/IP error is 'A remote host refused an attempted connect operation.' (errno = 79).
03/25/08 16:47:20 Error -50 opening session
03/25/08 16:47:20 cuSignOnResp: Error -72 reading SignOn response from server.
03/25/08 16:47:20 sessOpen: Error -72 receiving IdentifyResp verb from server
03/25/08 16:47:20 ANS9201W LAN-free path failed.
I should add that when I issue "dsmc", this node connects to the server without issues and doesn't add any records to dsmerror.log.
There is also sometimes too many sessions when I issue "q sessions" to the storage agent:
tsm: SO-TSM>ted-san:q se
ANR1699I Resolved TED-SAN to 1 server(s) - issuing command Q SE against
