Upgrading to S7800 PMF CRUs

ManualsBrandsHP ManualsServerHP Integrity NonStop Service Procedures

Use this procedure to upgrade both PMF CRUs in an enclosure to S7800 PMF CRUs.

See Change History for changes made to this procedure.

S7400 and S7600 PMF CRUs can be upgraded online, but S7000 PMF CRUs must be

upgraded offline. See

NTL customer site: PMF CRUs That Can Be Upgraded Online and Coexist

Permanently in Mixed Systems.

NTL employee site: PMF CRUs That Can Be Upgraded Online and Coexist

Permanently in Mixed Systems.

●

Notes:

Do not attempt to upgrade to unsupported configurations. ●

IOMF and IOMF 2 CRUs are supported on S7800.●

IOMF 2 CRUs connected through MSEBs are needed to take advantage of

ServerNet 2.

●

IOMF and IOMF 2 CRUs can coexist in an I/O enclosure for a brief period while

performing an online upgrade. For performance reasons, both IOMF CRUs in an

enclosure must be IOMF or IOMF 2 CRUs.

●

You cannot reconfigure a Tetra 8 to a Tetra 16 topology online. You must

perform this expansion offline.

●

Caution: Ask your service provider to verify the daughter board connectors on the

PMF CRU are fully seated before installing the CRU. Instructions are in Technical

Bulletin TB20051B. This affects S7800, S76000, S86000, S78000, and S88000.

Preparing for the Upgrade

1 If you are upgrading from S7000 to S7800 PMF CRUs, a power shelf and

two power supplies must be installed in each processor enclosure by a

trained service provider. Contact your service provider for more details.

Upgrading to S7800 PMF CRUs Use this procedure to upgrade both PMF CRUs in an enclosure to S7800 PMF CRUs. See Change History for changes made to this procedure. S7400 and S7600 PMF CRUs can be upgraded online, but S7000 PMF CRUs must be upgraded offline.

If you are upgrading from S7000 (NSR-W) to S7800 (NSR-J), you must change the processor type entry in the CONFTEXT file ALLPROCESSORS statement to NSR-J before you replace the PMF CRUs. You can specify only one processor type. S7000 cannot be in a system with mixed processor types. After changing the CONFTEXT file, you must perform all required DSM/SCM requests to create a new SYSnn. System load of the new SYSnn is required after the new hardware is installed.

needed to replace them on one fabric at a time. See Upgrading SEBs to MSEBs on One Fabric at a Time. Required Tools and Documentation For this upgrade procedure, you need: ● The G06.nn Software Installation and Upgrade Guide (G06.16 or later RVU). ● The appropriate OSM action or guided procedure for replacing PMF CRUs. Required Software S7800 was introduced for G06.23. It is supported on G06.24 and later, on G06.23 with one SPR, and on G06.16 through G06.22 with other OSM or TSM SPRs. G06.16 through G06.

● option is available on all S-series systems except S7000. G06.06 provides a new disk bootstrap program. If you are migrating from an RVU prior to G06.06, you must replace the disk bootstrap microcode with the new version. Upgrading to S7800 PMF CRUs You must perform these steps in exactly the order listed here, even if you have successfully completed previous upgrades by doing these steps in a different order. 1 Install the SUT and appropriate RVUs. For further instructions, see the G06.

10 Replace one PMF CRU by using the OSM action or guided replacement procedure. When the procedure prompts you to physically replace the PMF CRU, a help button appears that enables you to access detailed instructions. Caution: Verify the daughter board connectors on the PMF CRU are fully seated before installing the CRU. See Tech Bulletin TB20051B.

Upgrading SEBs to MSEBs on One Fabric at a Time Note: If you are replacing SEBS and ECL cables prior to installing the G06.17 or later RVU, use OSM software or TSM server product version T7945ABB (from G06.16) and TSM client 2002B T8154ABB to replace them on one fabric at a time. These products bring down the selected SEB or MSEB and all SEBs or MSEBs that are cabled to it. On earlier versions of TSM, you must perform separate operations to bring down both ends of a link before replacing a cable.

Change History for Upgrading to S7800 PMF CRUs August 10, 2005 ● ❍ Updated to clarify configuration rules, MSEB requirements for inter-processor cables, and SEB or MSEB requirements for processor-to-I/O enclosure cables. January 31, 2005 ● ❍ Added caution to ensure PMF CRU daughter board connectors are fully seated before installing the CRUs. Instructions for service providers are in Tech Bulletin TB20051B. ❍ Added caution under required software for upgrading to G06.
