These release notes support V4.3.2 of the SequentLINK software product. Read this document before you install, configure, or run this release of SequentLINK.
SequentLINK V4.3.2 runs on DYNIX/ptx V4.2.3 and above, on Symmetry® and NUMA-Q® systems.
SequentLINK V4.3.2 adds the following enhancements:
- Checks for sufficient space in /tmp before either Health Check Event or Data Transfer Event is run.
- Returns additional system files.
For DYNIX/ptx V4.6 and up:

SequentLINK V4.3.2 requires the following:
- DYNIX/ptx operating system, version 4.2.3 or higher.
- ptx®/TCP/IP V4.0.3 or higher (for Internet E-mail only)
In order for SequentLINK V4.3.2 to collect performance data, the following requirements must be satisfied:
- DYNIX/ptx operating system, V4.4.2 or later
- ptx/PDC V1.1 or later
NOTE:
ptx/PDC may not have been installed by IBM NUMA-Q Manufacturing. If your system is running DYNIX/ptx V4.4.2 or later and you want SequentLINK to run Performance Check, ensure that ptx/PDC is installed.
NOTE:
ptx/PDC V1.1 is included in the release of DYNIX/ptx V4.4.4. ptx/PDC V1.0 (which is not sufficient to run Performance Check) was released with DYNIX/ptx V4.4.2. To collect performance data on systems with DYNIX/ptx V4.4.2 and SequentLINK V4.3.2, Version 1.1 of ptx/PDC must be installed.
The OS Availability Event uses information from the /var/adm/wtmp file. Therefore, in order for this event to function properly, this file must exist and must be in this location. (There is a symbolic link to this file from /etc/wtmp .)
Beginning with DYNIX/ptx V4.5.0, a new file holding only wtmp accounting records was created. SequentLINK V4.3.2 will use this file when available, eliminating the need for /var/adm/wtmp .
In order for SequentLINK to monitor cluster availability, the following requirements must be met:The Cluster Availability Event uses information from the most recent /usr/adm/ktlog file. Therefore, in order for the Cluster Availability Event to function properly, this directory must exist and must be in this location.
- ptx/CLUSTERS V2.x is installed and configured.
- klogd is running.
- OS Availability Event is enabled.
SequentLINK has a minimal impact on your system's resources. Reboot or kernel reconfiguration is not necessary.
