Problems with latest QLogic driver

The latest QLogic driver for QLogic based FC HBAs with version 9.1.9.25 is known to cause some problems with Command View EVA. After upgrading to this version, CV is not able to see the EVA storage systems.

HP has released an advisory (

Changing back to an older version (e.g. 9.1.8.x are known to work without problems) is also possible.

We encountered another problem with this driver release in our demo lab. After upgrading our two HyperV R2 servers to this version, they were unable to see any fibre attached storage from our DataCore SAnsymphony-V installation. The two FC HBAs showed up in the port overview als mode "unknown". Normally you would expect here to see "Initiator" as fc mode. With the mode set to "unknown" we were unable to serve storage to the HyperV servers.

After downgrading the Qlogic driver to version 9.1.8.28 everything works as expected. 
So please be careful with the latest QLogic driver version, they sometimes have some strange side effects.
