The Cisco 9100 *is* a QLogic switch as well, so this should be pretty straightforward. Both switches must have the following settings the same:

R_A_TOV
E_D_TOV
Domain ID
BB_Credit on the ISL ports
 And you'll probably need to set all switches to Open Fabric mode. You then connect one switch to the other and the two switches will form a fabric with the new, unconfigured (ie unzoned) switch taking the configuration of the master switch. If you have done no configuration on the QLogic blade switch, plug it in to the Cisco 9100. It should attempt to form an ISL by default. If it does not, then check the settings noted above. If it still won't play nicely, then check the Cisco and IBM documentation listed below.
