Upgrading to S7600 PMF CRUs

ManualsBrandsHP ManualsServerHP Integrity NonStop Service Procedures

Use this procedure to upgrade both PMF CRUs in an enclosure to S7600 PMF CRUs.

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

offline. See PMF CRUs That Can Be Upgraded Online and That Can Coexist

Permanently in Mixed Systems.

See Change History for changes made to this procedure.

Notes:

Do not attempt to upgrade to unsupported configurations. ●

IOMF and IOMF 2 CRUs are supported on S7600. IOMF 2 is needed to take

advantage of ServerNet II.

●

IOMF and IOMF 2 CRUs can coexist briefly in an enclosure for online upgrade.

For performance reasons, both IOMF CRUs in an enclosure must be IOMF or

IOMF 2 CRUs.

●

Preparing for the Upgrade

1 If you are upgrading S7000 PMF CRUs to S7600 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.

2 If you are upgrading from S7000 (NSR-W) to S7600 (NSR-E), you must

change the processor type entry in the CONFTEXT file ALLPROCESSORS

statement to NSR-E 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. Failure to change the processor type

causes an immediate %100441 halt when the new SYSnn is loaded. See the

appropriate G06.24 or later Release Version Update Compendium for

migration and fallback details.

3 Upgrading the SEBs to MSEBs is not a requirement for S7600. If you are installing MSEBs and replacing the interconnecting ECL cables with serial copper or fiber-optic cables, you can perform these upgrades either offline or online 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.

For systems with four or more processors, you might need to make the extended segment sizes for the TMFMON and TMP processes larger than the default sizes before you upgrade PMF CRUs. You might also need to alter the TransCountThresh values to support larger transaction volumes. See HS02519D for details. Required Tools and Documentation For this upgrade procedure, you need: ● The G06.nn Software Installation and Upgrade Guide (G06.17 or later RVU).

Change History for Upgrading to S7600 PMF CRUs January 31, 2005 ● Added new step 2 to Preparing for the Upgrade, to change the processor code in the CONFTEXT file if you are upgrading from S7000. Failure to change the processor type halts the system when the new SYSnn is loaded. June 07, 2004 ● Restructured notes and moved upgrade and configuration rules to new topic.
