In the knowledgebase search - mention "emc171918" only - you may narrow down the result by selecting Resource as "Support Solutions".

The Knowledgebase search is having a quicklink on your Powerlink Home page most likely - if not negotiate as follows to go to Knowledgebase search -

Host must first be removed from its Storage Group(s) and deregistered from the CLARiiON array:

Remove host from Storage Group. See solution emc14239 ("How to connect or disconnect servers from Storage Groups using Navisphere Manager").

Add host to SAN environment:

Configure Fibre Channel (FC) switch. Refer to switch configuration guide for specific details on configuration switch IP address, password, ports, etc.
Attach hosts to Fibre Channel switch port.
Attach CLARiiON to Fibre Channel switch port.
Add HBA WWN and CLARiiON storage processor (SP) WWN to switch zone.
Verify host HBA/initiator is visible from Navisphere Connectivity Status. Refer to solution emc35436 for more information.
Register host with CLARiiON array.
Add host and LUNs to CLARiiON Storage Group.
