An rc=-50 issue is always a network-related issue. Either the OS's network interface is damaged, or there is something wrong with the physical network. Unless the TSM option parameters are incorrectly set, it has nothing to do with TSM.

New site, P595 AIX 5.3 with many LPARs. Most LPARs run SAP and TDP for ERP Oracle. TSM Client is at 5.5.1.0 TSM server. is 5.5.1.0. Both client and server are in different LPARs on the same P595. SAP instance has 3 interfaces, one for the application, one for management purposes and one for backups. These are all virtual networks using the VIO server lpar. The client and server have backup addresses on the same subnet, and TCPADDRESS is set in the dsm.sys stanzas to force the backup down the backup network. Backups have been working, but now fail. Both ba client and TDP start getting tcp/ip failure rc -50 when trying to initiate the backup session. Client can ping server. If I ping the client from the server, then the tcp/ip failure goes away and I can get a good backup, but then the next day's backup fails. I'm thinking this has to be an AIX problem because the backup packets should never get out of the virtual backup lan. Thus it can't be firewall or external routing. The default gateways look correct and so the packets should be going out of the right interface and finding their target, but obviously are not. The lpars are all built from the same image and several of them are exhibiting the same issue. The ping fix always works, temporarily. Any ideas on how this can be fixed permanently, or debugged, will be gratefully received. Regards Steve Steven Harris, TSM Admin Sydney Australia No virus found in this incoming message.
