FCO CI780-F1-1005, Numerous funct errors ("arbitration timeout") et al

This Field Change Order (FCO CI780-F1-1005) addresses multiple functional errors in CI780 systems, such as "arbitration timeout," "internal queue retry error," "BUFFER LENGTH VIOL.," and V6.0 microcode-related cluster hang problems. The FCO mandates retrofitting CI780s to Revision Level "F1" by upgrading the L0101 Part Revision to "J1" and the CI780 microcode to V7.0.

The upgrade process involves replacing six pluggable PROMs on the CI780's L0101 module with new V7.0 PROMs and updating the CI780.BIN file on the console media to V7.0. The detailed procedure includes backing up existing console media, transferring the V7.0 microcode and associated diagnostics from supplied magtapes (EQ-01422-02/03 kits) to the system disk, then moving the CI780.BIN V7.0 file to the console media. Following this, the old V3.0 PROMs are removed, and new V7.0 PROMs are installed, requiring a full system shutdown, proper use of an ESDS-Velostat Kit, and careful handling of components. The L0101 module is then marked "J1."

Post-installation, the system is powered up, and Level-III diagnostics (EVGAA/B 3.4) are run to verify the CI780's functionality. For VAXCLUSTER environments, it is strongly recommended that the customer perform all system shutdown and boot-up operations to avoid impacting their applications. The document also emphasizes maintaining a duplicate copy of the console media with older microcode and retaining the old PROMs for potential downgrades. Final steps include verifying the microcode revision displays as "0007" for both CI780.BIN/RAM and L0101 ROM, reconnecting network cables, and updating documentation.
