Upgrading to S76000 and S86000 PMF CRUs

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.

To replace the SEBs on one fabric at a time, run a separate replacement

procedure for each SEB to be replaced (you can use OSM replace actions

or Replace SEB or MSEB guided procedures):

Start the procedure to replace one of the SEBs.1.

Run the procedure until you are prompted to Replace the SEB. Then

start a new copy of the procedure for another of the SEBs, continuing

up to the manual replace prompt.

Repeat Steps 1 and 2 until the procedures for all the SEBs to be

replaced in one fabric display the manual replace message.

Physically remove all of the selected SEBs and ECL links, and install

the MSEBs and new links.

Complete one procedure. Allow this copy of the procedure to complete

before repeating for each of the other replacements.

Replace the SEBs and cables in the other fabric, using this procedure, after

verifying that the newly installed MSEBs and links work properly.

The SEBs in slot 53 and slot 54 of all processor enclosures, the IOMF CRUs

in I/O enclosures, and the SEB-to-IOMF CRU cables can remain the same.

2 If S7000 PMF CRUs are being upgraded to S76000 or S86000 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.

3 If you are upgrading from S7000 (NSR-W), you must change the processor

type entry in the CONFTEXT file ALLPROCESSORS statement before you

replace the PMF CRUs. Enter NSR-X (for S76000) or NSR-H (for S78000).

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.
