Wonder if you encounter any issue connecting Mac Pros (with Apple/LSI FC HBAs and Mac OS X 10.5.x) to QLogic FC switches with 7.4.0.16 firmware?
No issues. Works well.
Should I update the existing QLogic 5602 to the same firmware as the 5800V?
If you want to stack, then they should all be on the same firmware.
I read in QLogic forum, it’s recommended to update to 6.8.0.03 first, then to 7.4.0.16.
Wonder if you have any similar experience?
This is recommended only if you need to do a hot upgrade (without losing any connectivity). If you can do a reset on teh switches (meaning take the san down, update firmware, restart switches, bring san back up) then you can go straight from 5.x to 7.4.0.16. This is what we did and it’s all working very well, qlogic is very solid.
