HS22 type blades are irrelevant; there is nothing special about them to setup.
Make certain your (Cisco) switch has IGMP Snooping enabled -- you will not be able to form a cluster without it on. Conversely, if you are using a Server Connectivity Module (SCM) only, disable IGMP Snooping on that device.
If you are using GFS / GFS2 clustered filesystems, your fence device is the BladeCenter's AMM. Make certain you setup an account in your AMM that is allowed to power up / power off each blade in its chassis.
We have two AMMs for redundancy, Adama and Cain, and created a local account "cluster", i.e.,
<clusternode name="zodiac" nodeid="8" votes="1">
<device blade="8" name="Adama"/>
<device blade="8" name="Cain"/>
<fencedevice agent="fence_bladecenter" ipaddr="adama" login="cluster" name="Adama" passwd="********"/>
<fencedevice agent="fence_bladecenter" ipaddr="cain" login="cluster" name="Cain" passwd="********/>
