In reply to this post by bharat singh-2 On Wed, Jul 23, at We all like an interesting experiment or two. If I recall correctly, the firmware that is loaded on boot is loaded into RAM on the card, not flashed.

QLogic FC Target Driver How-to for 22xx/23xx/24xx/25xx/26xx Adapters
I know and understand some of the risks. For Fibre Channel cards in Local Loop topologies it is strongly recommended that you set this value to non-zero.
The OS does handle it and I get fantastic speed for a few minutes until another happens then I get a pause, reset and again. Moreover i have seen the issue on older firmware 5. Notify me of new comments via email.

FC-Tape is automatically enabled when connecting controller that supports it to a target that supports it. At least then you may be able to live with middling performance from freebsd.
On Wed, Jul 23, at 9: First of all, looking through dmesg output, this RHEL 7 workstation has loaded the driver for the Qlogic card.
It downloads firmware into RAM on the card, and then tells the card to execute it. Essentially my problem is freebsd doesnt handle all the dammed controller commands, it doesnt deal with all the HD’s instructions properly.
The current problem other than it takes an eon to boot the san and vmware and have them play nicely together is frdebsd when writing to the san, I get wonderful burst of quite brilliant speeds, the speeds I expect, however I something resets and the whole process pauses stops mid transfer, then bursts again for a short period of sustained transfer before dieing again.
Thankyou all for taking the time to respond. If so, you have the option of running FreeNAS on redundant datastores, ala one of jgreco’s other threads https: Instead, you just tell the driver not to download firmware and it uses the firmware that’s flashed into the card.
