GESA
If you are planning on using the new TMF format 2 audit trail format, migration issues
might apply for DP2. The T9053G11 PVU provides support for TMF large audit trails
and two new disk attributes for REVIVE. See the T9053G11 softdoc.
GESA
Any Gigabit Ethernet ServerNet adapters (GESAs) installed while migrating to G06.28
must be removed from the system during any fallback to an RVU prior to G06.16.
G4SA
Any Gigabit Ethernet 4-port ServerNet adapters (GESAs) installed while migrating to
G06.28 must be removed from the system during fallback to an RVU prior to G06.24.
KMSF
Beginning with the G06.27 RVU, the default value of MAXEXTENTS for default Kernel-
managed swap files increases from 128 MB to 256 MB, resulting in maximum default
swap file sizes of 256 MB per swap file. For more information, see the Kernel-Managed
Swap Facility (KMSF) Manual.
Minimum Memory Requirements
Beginning with the G06.16 RVU, NonStop S-series servers require a minimum 256 MB
of main memory.
NonStop Operating System - NSK Utilities (T9070AAK and Later)
Under rare circumstances, the branch prediction logic of a NonStop S-series server
can cause a hardware error freeze (HEF). In T9070AAK and later product versions of
NSK Utilities, the patch utility is applicable to only S74000/S7600 and S72000/S7400
processors. If you have S74000/S7600 processors, you can still continue to use
T9070AAK. The utility is not needed for the latest processors S7800, S78000, and
S88000. If you have S76000 or S86000 processors, see HS02830. For detailed
information on the branch prediction logic utility, including its applicability to your
environment, see HS02774F or later. Note that whenever the processor is reloaded,
offline maintenance activities can make the patch inactive.
