DP2 Fallback SPR

Once you have installed the G06.29 or later RVU and created Format 2 files, a DP2

fallback SPR is required to safely fall back to a pre-G06.28 RVU. The required DP2

fallback SPR is T9053G11^AQS. If you fall back and then attempt to access a Format

2 file, and this SPR is not installed, outages caused by data corruption or CPU halts

are likely to occur.

T9053G11^AQS is preinstalled in systems running G06.28; for those systems, no

action is required. You can install the SPR on systems running G06.24 through

G06.27, as long as all prerequisites are included:

•

If you are currently running the G06.23 RVU, consider upgrading to G06.28 before

upgrading to G06.29 to facilitate fallback if fallback becomes necessary.

•

If you are currently running a G06.24 through G06.27 RVU, HP strongly

recommends that you install the fallback SPR before migrating to G06.29. The

installation of T9053AQS requires a system load.)

The DP2 fallback SPR requires that the following SPRs also be installed:

Table 4-3. SPRs Required for NonStop SQL/MX Release 2.0 Fallback

Product

SPR (or

Superseding) Notes

DP2 T9053APO, if the

system uses the

online disk remirror

feature

T9053APG, if the

node does not use

the online disk

remirror feature

If applied, a system load is required before

upgrading to the new RVU. The SPRs are

applicable to the G06.13 through G06.22

RVUs. See DP2

on page 2-3.

NonStop SQL/MP T9195A

To minimize the risks involved with falling

back without a clean TMF shutdown, use

the appropriate SQL GOAWAY utility to

drop all SQL/MX objects and their resource

forks. Before doing so, see Migration

Considerations for NonStop SQL/MX

Release 2.1.1 on page 2-12.

TMF T8607AF

No fallback SPRs are required if you are

running on G06.18 through G06.23 or if a

TMF clean shutdown is performed and other

installation and fallback steps are taken for

NonStop SQL/MX Release 2.0.

WARNING. If you do not install the DP2 fallback SPR before migrating to G06.29 and a

fallback becomes necessary, you must perform a system load on the prior RVU, and then,

before using any OSS files, you must install and coldload to the DP2 SPR.
