Install/Upgrade IT Product without reboot update iomax values for hba cards

[AmareswaraReddy]

Hi,

Can some one help me on this.

1. io max read must be 256kb
2. io max write must be 256kb

Value can be updated (tunned) but because it’s Driver registry update.

How to and where to change the io max read & write values for Emulex HBA card?

Thanks,

Amaresh

2. io max write must be 256kb
Value can be updated (tunned) but because it’s Driver registry update reboot is required (but could be done during patch day activity).

Thanks,
