These release notes support Version 1.1.3 of the ptx/CTC software intended for use with Symmetry® 5000, and NUMA-QTM 2000 computer systems. ptx/CTC manages mission-critical applications during and after cluster transitions.
Read this document before you install or run this release of ptx/CTC. If you encounter problems with ptx/CTC, refer to the "Problem Report Summary" section for descriptions of known problems with this version of the software.
This version of ptx/CTC can be used with the following systems:
The following products must be installed on your system to use V1.1.3 of ptx/CTC:
DYNIX/ptx® V4.5
ptx/CLUSTERS V2.2
ptx/SVM V2.2, if using ptx/CTC for ptx/SVM failover.
ptx/TCP/IP V4.5.x, if using ptx/CTC for IP failover.
ptx/CFS V1.1.0, if using ptx/CTC for CFS object failover.
ptx/CTC V1.1.3 provides failover support for ptx/SVM private disk groups in a cluster failover scheme that do not use shared disk groups. Use the SVMPRIVDG method to failover private ptx/SVM diskgroups . When creating the ptx/CTC object name for this method use the exact name of the diskgroup as it is known to ptx/SVM.
All ptx/CTC error messages are now written to the Error Event Subsystem log instead of the ptx/CTC local logs. The start, stop, and verify actions still record results in the local object log at /usr/ctc/logs.
This version of ptx/CTC supports failover in clusters with greater than two nodes.
For installation instructions, refer to the DYNIX/ptx and Layered Products Software Installation Release Notes. ptx/CTC V1.1.3 is now automatically installed when ptx/CLUSTERS V2.2 is installed.
The following problem reports are outstanding for V1.1.3 of ptx/CTC.
Workaround. Do not give two ptx/CTC objects the same name.
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.
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.
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.
Wordaround. Ignore messages.
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."
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.
The ptx/CTC Administration Guide, available on the online documentation CD-ROM, supports this release of ptx/CTC.
