Migration

The NonStop S88000 server is introduced at G06.24 and supported on G06.24 and

later RVUs. Before installing S88000 processors in the system, you must first install

the G06.24 RVU. See the G06.24 Software Installation and Upgrade Guide for more

information regarding software requirements for migrating.

The processor type for the NonStop S88000 server is NSR-Z. For information on

upgrading to a model 1974 (NonStop S88000 S-series) PMF CRU (PMF 2 CRU), see

the CSSI Web site.

Any system in which S88000 processors are installed must have modular ServerNet

expansion boards (MSEBs) in slots 51 and 52 in enclosures 1 through 8. You can still

use ServerNet expansion boards (SEBs) to attach I/O enclosures. If you upgrade to an

S88000 processor from a system not using MSEBs in slots 51 and 52, you must

replace SEBs with MSEBs as part of the upgrade. All cabling previously used to

connect SEBs must be replaced with serial copper or fiber-optic ServerNet cables

specific to the MSEB. ECL ServerNet cables are specifically disallowed when installing

MSEBs for upgrading to model 1974 PMF CRUs.

For compatibility of PMF CRUs and coexistence of enclosures in a system, see the

NonStop S-Series Planning and Configuration Guide.

Before you upgrade to G06.24 or later RVUs, if your system includes processors with

processor model 1951 (NonStop S70000 or NonStop S70000SE), you must change

the processor type from NSR-G to NSR-C in the CONFTEXT file, ALLPROCESSORS

statement. All other references to NSR-G are still valid. Displays or queries done on

the system return NSR-G if the PMF is a model 1951 PMF CRU (NonStop S70000) or

1951 PMF FRU (NonStop S70000SE).

Before upgrading the NonStop S7000 system (NSR-W) to NonStop S88000 (NSR-Z),

you must change the processor type entry in the CONFTEXT file. You can specify only

one processor type.

After changing the CONFTEXT file, you must perform all required DSM/SCM requests

to create a new SYSnn, including the new processor type. System load of the new

SYSnn is required after the new hardware is installed.

The S88000 does not require the branch prediction logic patch.

Fallback

For fallback, you do not need to downgrade the SP firmware to its previous version. If

you are falling back to an RVU prior to G06.16, you must return processor boot code

(T7892) back to the previous version and update the firmware before performing a

system load of the previous RVU.

See the G06.24 Software Installation and Upgrade Guide for information.
