All the extra software was a PITA, especially during kernel upgrades. I would also recommend a "quick start" guide to adding an EMC array only using the built in RHEL5 tools (plus SanSurfer) even if the functionality is reduced. thanks again for the info. > Regards, > Wayne. > > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Christopher > McCrory > Sent: Tuesday, February 27, 2007 8:17 PM > To: RHEL5 > Subject: [rhelv5-beta-list] qlogic FC HBA/ EMC > > Hello... > > I am testing RHEL5 with an EMC CX300 array with a QLogic QLA2340 > HBA. > Maybe someone else on the list is using these or can shed some light on > me.
