1-29
Gigabit Ethernet ServerNet Adapter (GESA)
(G06.16)
See the Interactive Upgrade Guide and Support Note S04057.
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.
Gigabit Ethernet ServerNet Adapter (GESA) (G06.16)
Any Gigabit Ethernet ServerNet adapters (GESAs) installed while migrating to G06.27
must be removed from the system during any fallback to an RVU prior to G06.16.
Gigabit Ethernet 4-Port ServerNet Adapter (G4SA) (G06.24)
Any Gigabit Ethernet 4-port ServerNet adapters (GESAs) installed while migrating to
G06.27 must be removed from the system during any fallback to an RVU prior to
G06.24.
Kernel-Managed Swap File Facility (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 (G06.16)
Beginning with the G06.16 RVU, NonStop S-series servers require a minimum 256 MB
of main memory.
NonStop Operating System - NSK Utilities (T9070AAK or Later)
(G06.22, 23, and 24)
Under rare circumstances, the branch prediction logic of a NonStop S-series server
can cause a hardware error freeze (HEF). 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.
