Windows Server 2008 Cluster Disk cannot bring online - System error 5018

I´ve created a Cluster Active/Passive over Windows Server 2008 Enterprise Edition x64 with two nodes . The specifications are:

Servers:HP Blade ProLiant BL480c G1.

HBAs:   QLogic QMH2462 4Gb FC HBA for HP c-Class BladeSystem

Storage: NAS EMC win Powerpath 5.2 as my MPIO

After i create the new cluster the disk attached are detected but not bring online with the message "The cluster resource could not be brought online by the resource monitor" and if a try to do it by the power shell with cluster res "Cluster Disk 2" /on it doesn´t work too, cause display the same message:

Bringing resource 'Cluster Disk 2' online...

System error 5018 has occurred (0x0000139a).
The cluster resource could not be brought online by the resource monitor.


Principaly the Cluster Log Says:
00000e2c.00000c5c::2008/11/18-22:09:17.059 ERR   [RES] Physical Disk <Cluster Disk 1>: OnlineThread: Error 1 bringing resource online.

.... and the same for all the other disk attached.

 I've tried a lot of conbinations with services offline on one node or powered off, etc.

This nodes was on a Win2003 Cluster with the same storage, So i don´t know if this could be some driver, compatibiliti, MPIO upgrade needed, or some specific with the new version or process to build and handle resourses by Win2008.


¿Does anyone know what could be the cause or some configuration that could help?

Until discover the specific problem or cause i´ll do the following i i´ll notice you if that work

- Ensure Microsoft STORPort hotfix Q943545 (ref: http://support.microsoft.com/kb/Q943545/en-us) is installed to both nodes.

- Upgrade to the latest EMC qualified HBA firmware (Boot code) 1.64 (BIOS v1.26)

- Upgrade HBA driver to the latest EMC qualified ver 9.1.7.16

- Flash HBA parameters NVRAM setting to correct HBA parameters to EMC approved settings.

(Ref: page 37 on http://filedownloads.qlogic.com/files/Driver/67902/QLogic_Windows_04_23_08.pdf.  
Also see page 124 to 126 for a procedure 'Updating the flash BIOS'... NVRAM settings for the HBAs can be flashed via SANsurfer by clicking Update NVRAM.) 

Thanks and i hope any comment.
