SP Firmware Requirement for Systems With Tetra 8

SP Firmware Requirement for Systems With Tetra 8 Topology
When preparing a system with the Tetra 8 topology for ServerNet Cluster connectivity,
you must upgrade the SP firmware to a version that supports clustering (shown in
Table 2-8 on page 2-23) before you perform a system load with G06.09 or higher.
Otherwise, the ServerNet Cluster processes $ZZSCL (SNETMON) and $ZZSMN
(SANMAN) will abend repeatedly when the system load is performed.
This requirement does not apply to systems with the Tetra16 topology.
Verifying the System Name, Expand Node Number, and Time
Zone Offset
Before you can add a server to a ServerNet cluster you must ensure that the system
name and system number (Expand node number) do not conflict with the name and
number of another node in the cluster. Also, you should verify that the system clocks
on all nodes in a cluster are set to the correct time zone offset.
To verify the system name and system number (Expand node number) and view the
time zone offset:
1. Log on to the system.
2. Use the Kernel subsystem SCF INFO command.
- > INFO SUBSYS $ZZKRN
For each server, record the system name and Expand node number on the Cluster
Planning Work Sheet. See the Cluster Planning Work Sheet (Example) on page 2-5.
For a blank copy of the Planning Work Sheet, see Appendix B, Blank Planning Forms.
For information about the system name, system number (Expand node number), or the
time zone offset, refer to the SCF Reference Manual for the Kernel Subsystem.
Planning for Compatibility With Other Expand Line Types
If you want to create a ServerNet cluster that operates with other Expand line types,
you must order individual profile products for the line types you are using. Profile
products include the following:
