HOW TO INSTALL FIRMWARE FOR QLOGIC FIBRE CHANNEL ADAPTER USING SAN SURFER GUI ON W2K3, ANY DOCUMENT?

http://networkadminkb.com/KB/a492/how-to-upgrade-the-firmware-of-qlogic-hbas-using-sansurfer.aspx

Thanks a lot dynamox..if possible can i know where can i change hba settings using san surfer GUI on W2K3 ?

1)Qlogic Driver Execution Throttle is 16 (Latest EMC approved setting is 65,535 when Hba speed is greater than or equal to 4 Gbps)2)Qlogic Driver Port Down Retry Count is 16 (EMC approved setting is 45)3)Qlogic Driver Link Down Timeout is 8 (EMC approved setting is 45)4)Qlogic Driver LUNS Per Target is 128 (EMC approved setting is 256  ..?

if you are using EMC "approved" Qlogic drivers, those parameters should be already set. Make sure to use drivers from EMC OEM section on their website

Thanks for info .. if possible send your email so i can send my procedure Doc for a quick check ?

you can post it here

just asking: why would you want the execution throttle to be as high as 64k? You'll be overloading the storage ports if you do this. On a VNX each port can only have 1600 outstanding IOs at any time, so if an HBA is allowed to have 64k IOs open, you're bound to get yourself in troube.

Hi,

Execution Throttle                          : from 16 to 256  (Set to 65,535 for 4GBs and over)

Port Down Retry Count                   : from 16 to 45

Link Down Timeout (seconds)          : from 8 to 45

LUNs Per Target                             :from 128 to  256 These are the settings recommended by EMC for PPME migration from CX-3 TO VNX ..  Thanks

I believe this is set this way, because it is the Microsoft Storport driver that controls the throttling of I/O. We set the HBA driver to the max, and the MS driver is supposed to throttle as necessary when queued.
