DP2 (G06.16, G06.23, G06.24)

If you set the AUDITTRAILBUFFER or the SQLMXBUFFER attribute to 128 or more,

you need to reset these values to 0 before falling back to G06.16 or an earlier RVU. If

you fail to do so, TMF might not start, or a disk volume might go offline. You can

recover from this situation by using the SCF ALTER command. See the Interactive

Upgrade Guide for details.

If you are planning to use SQL/MX Release 2.0, HP recommends that you apply one of

these DP2 fallback SPRs on your current SYSnn before upgrading to G06.23 or

G06.24:

•

T9053AOY, if the system uses the online disk remirror feature

•

T9053AOZ, if the system does not use the online disk remirror feature.

After installing the fallback SPR, test it sufficiently for production use. Then you can

migrate to G06.23 or G06.24. If you are using SQL/MX Release 2.0 and you have to

fall back to a previous RVU, and you have created SQL/MX objects or audit records,

you must have this fallback SPR installed on your current SYSnn.

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 softdoc T9053G11.

Gigabit Ethernet ServerNet Adapter (G06.16)

Any Gigabit Ethernet ServerNet adapters (GESAs) installed while migrating to G06.24

must be removed from the system during any fallback to an RVU prior to G06.16.

Minimum Memory Requirements (G06.16)

Beginning with the G06.16 RVU, NonStop S-series servers require a minimum 256 MB

of main memory.

NonStop Kernel (NSK) Utilities (T9070AAK) (G06.22, 23, 24)

Under rare circumstances, the branch prediction logic of an 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 newest

processors S7800, S78000, and S88000. If you have S76000 or S86000 processors,

read HS02830. For detailed information on the branch prediction logic utility, including

its applicability to your environment, read HS02774 (HS02774F). Note that whenever

the processor is reloaded, offline maintenance activities can make the patch inactive.
