TS/MP 2.5 Release Supplement

A Backing Out Your Installation to TS/MP 2.0
This appendix includes these topics:
• “Planning the Backout” (page 90)
• “Performing the Backout” (page 90)
NOTE: Before backing out and returning to TS/MP 2.0, you must consult HP support if you have
installed TS/MP 2.1 or later releases and have run applications that use Pathsend requestors.
Planning the Backout
The following prerequisites are required before planning to back out your system:
• TS/MP 2.0 cannot reside in the same system as TS/MP 2.5.
• The ACS subsystem must be stopped and removed from the system configuration before
reinstalling TS/MP 2.0.
• Components of TS/MP 2.5 that conflict with TS/MP 2.0 must be deleted before reinstalling
TS/MP 2.0.
• TS/MP 2.0 LINKMON must be added to the system configuration.
Performing the Backout
To perform the backout to TS/MP 2.0:
1. Stop the Pathsend requestors.
2. Prepare a new system image that contains TS/MP 2.0.
3. Stop the ACS subsystem through SCF.
4. Stop the Domain Controller Process and delete the ACS subsystem from the Persistence
Manager's configuration database ($ZPM).
5. Add the TS/MP 2.0 LINKMON to the system configuration.
6. Restart the system with the new system image.
Adding TS/MP 2.0 LINKMON Configuration
The TS/MP 2.0 LINKMON must be added under the Kernel Subsystem Manager process ($ZZKRN)
using the SCF ADD PROCESS command.
To add the TS/MP 2.0 LINKMON configuration, use the SCF ADD PROCESS command interactively
or in an OBEY file.
