Upgrading to S7600 PMF CRUs

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. 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.

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.

See NonStop S-Series Topologies for cabling information.

For G06.10 RVU, when a PMF CRU is upgraded online and a tape device

is configured to that PMF CRU, the GRT might fail, the peer processor will

not be able to access the new PMF CRU adapter, subsequent controller

downloads to all SACs of the adapter will fail, and none of the disk and tape

paths through the adapter will come up. See HS02633 for the workaround

and fix.
