Considerations for Upgrading SNETMON/MSGMON
and the Operating System
Considerations for Upgrading SNETMON/MSGMON and the
Operating System
The following considerations apply when you upgrade SNETMON/MSGMON and the
operating system:
•
SNETMON/MSGMON and the operating system support up to 16 nodes since
G06.09. This support allows the coexistence in a 16-node cluster of ServerNet
nodes running G06.09 or a later G-series RVU. G06.13 with T0294AAG (or a
superseding SPR) and later G-series RVUs (no SPRs required) support up to 24
nodes.
•
A version dependency exists between SNETMON/MSGMON and the operating
system running on the same node. Nodes running any compatible combination of
SNETMON/MSGMON and the operating system can interoperate over the cluster.
Nodes running any incompatible combination of SNETMON/MSGMON and the
operating system cause SNETMON/MSGMON to abend on the local node due to a
version mismatch error. Version checks between SNETMON/MSGMON and the
operating system are performed by SNETMON/MSGMON when the
SNETMON/MSGMON process starts.
Table 4-28 provides version and compatibility information for
SNETMON/MSGMON and the operating system.
•
Operating system upgrades require a system load, but you can perform them at
your convenience. You can upgrade SNETMON/MSGMON from any RVU.
However, you must observe the version dependencies between
SNETMON/MSGMON and the operating system.
•
Upgrades of the operating system in individual nodes across the cluster are
possible, but they require appropriate migration rules for other software
components.
