Hi all

I have blade system, one of amazing things i've discovered is the emulex hardware, now i can login from iscsi emulex bios to any iscsi target i want. But I don't know what happen when operative system starts. I mean, I have a Centos 6.X installed.

Then, I usually do

yum install iscsi-initiator-utils and then

iscsiadm --mode discovery --type sendtargets --portal 10.0.0.100

and then, I login in target and format the iscsi device,

but now I know there is installed hardware like emulex I don't know if Im doing right. Is this ok ? Or I have to install some different driver from Emulex to Linux in order to use Emulex Iscsi Card of my server?

Thanks guys

sOLVED

HP driver for this emulex card is not ok. You have to download driver iscsi from emulex web.
