Microcode Maintenance
When a new level of SCSI interface card microcode or disk drive microcode becomes
available, that microcode and the appropriate installation instructions are put onto the
web support page (see “Web Support Page” in “Appendix A. Additional Information for
RISC Systems”). The supplied installation instructions ensure that the microcode is
downloaded to the correct location.
To update the 2104 vital product data (VPD) that is held in the using system, you might
need to reconfigure the 2104 to the using system. For more details, see “Configuring a
2104 to the Using System” in “Appendix A. Additional Information for RISC Systems”.
