Open Problems in ptx/CTC V1.1.4

The following problem reports are outstanding for V1.1.4 of ptx/CTC.

229797
Two objects of type FS can be logged to the same /usr/ctc/logs file.

Workaround. Do not give two ptx/CTC objects the same name.

233412
ctcadm interactive mode exists when unknown command type is given.

Workaround. If you enter the ctcadm command at the UNIX shell prompt, it will accept standard input as arguments. The acceptable arguments should follow the syntax for the ctcadm command as described in the ctcadm man page. An invalid syntax will terminate the interactive mode.

236166
ctcadm passes environment through to method. Subsequent ly, any methods that are run manually inherit a different environment than the environment that would exist during an availability transition.

Workaround. Since the ctcadm command is run as root, the root environment is inherited by ctcadm when performing operations such as start, stop, and verify. Perform failover tests manually with root environment by first typing su - root.

237168
ptx/CTC menus were not reinstalled after upgrading ptx/CLUSTERS.

Workaround. Always install ptx/CLUSTERS and ptx/CTC together. If you have already installed ptx/CLUSTERS, re-install ptx/CTC from the CD-ROM so that the menus will reappear.

240975
Spurious ktlog error message node is not a cluster member.

Wordaround. Ignore messages.

241320
ctcd missing from /etc, giving error message, "Could not initialize, perhaps CTC_CONFIG_FILE not readable or database path not set."

Workaround. Stop ptx/CTC, set the database location, and then restart ptx/CTC. This procedure is described in the ptx/CTC Administration Guide, in the section titled "Creating Your ptx/CTC Configuration."

245887
ptx/CTC retains knowledge of old system names.

The ptx/CTC database retains knowledge of old node names. This occurs if you permanently remove nodes from the cluster or rename a node in the cluster. This causes extraneous messages in the EESlog file.

Workaround:

  1. Unload (save) the ptx/CTC database to a temporary file on the system.

  2. Stop ptx/CTC on all nodes.

  3. Zero the partition where the ptx/CTC database was loaded.

  4. Restart ptx/CTC on all nodes.

  5. Reload (restore) the ptx/CTC database that was saved to the temporary file.
