Description Marcus Barrow 2009-01-27 04:34:55 UTC
Testing at QLogic has discovered a word endianness problem when programming the flash on a PPC machine.

This would cause the FLASH device to become corrupt and render the card unusable until properly programmed.

I have verified fix on IBM JS21 blade server with QMI2472 IBM eServer Blade Center 4Gb Fibre Channel Expansion Card CFFX. Using SCLI version scli-1.7.1-23.ppc64.rpm, I was able to update flash image as well as modify hba parameters without observing any flash corruption.
