*************************************************** MEMO TO USERS = NONE ENDSET APARTXT IX68816 = Replica is not the master (dce / sec) The DFS file server configuration failed on two different systems. The error message on one system (p162) was: Detailed Error Messages: Configuring DFS Fileset Database Machine (dfs_fldb)... Current site is: registry server at /.../dce.rz.uni-karlsruhe.de/subsys/dce/sec/nzdce1 Domain changed to: account ?(rgy_edit) Unable to add \"hosts/p162/dfs-server\" - Replica is not the master (dce / sec) APARTXT IX69440 = dfs client looses contact with dfs server When a DFS client traverses a fileset mount point that points to an illegal fileset name, the DFS client will mark the DFS fileset location server down. This is disruptive to the overall usage of that DFS client. APARTXT IX69951 = DFS client hangs in TSR with a DFS server DFS data becomes unaccessible from a DFS client. A dump of the DFS trace syslog \"dfstrace dump\" \ APARTXT IX70165 = KRPC may not work with future versions of AIX The DCE Kernel RPC (KRPC) is using networking services which may not be compatible with future versions of the AIX operating system. APARTXT IX70166 = open() returns errno 127 accessing backup fileset Certain types of responses transmitted very close together from the DCE KRPC can result in the first response containing information from the second response. The problem is likely to be triggered at a DFS server with newer development level versions of DFS client code which have not yet been released to the field. When this happens DFS clients may return spurious errors to applications accessing DFS data. Reading and writing of file data are not subject to this condition. APARTXT IX70168 = Protect DFS from AIX duplicate port granting bug Access to DFS data may stop at a client or a server may stop serving DFS data. The DFS dfstrace syslog output will have messages consistently indicating communication failures. The output of netstat -an will show the same IP port number more than once. This happens when AIX incorrectly grants the port number DFS is using to another process. Typically that process is inetd. Once that happens, inetd will end up getting network traffic intended for DFS and DFS will stop working. APARTXT IX70169 = set KRPC debug level with env var when running dfstrace setset Currently support has to ship a special command to the customer in the field in order to enable a more detailed level of trace in the DFS Kernel RPC (KRPC). This is often not practical. APARTXT IX70170 = cm icl trace marked ERR should be INF The following message is tagged as an error (ERR:) when in fact it is just informational.
