Cannot see new MSA (2324FC) LUNS on RedHat 4.0 hosts

We have a customer running Oracle over 2 x RedHat 4.0 hosts currently using an IBM DS4700 for storage via Fibre Channel.  

To increase disk space on a temporary basis, I have presented,  via the same Fibre switches,  an MSA 2324FC to the 2 x Redhat 4.0 hosts (HP Proliant DL380 G5) and also 1 x windows 2003. 

I have successfully create a volume and presented it to the Windows 2003 box. However, i cannot seem to ge the RedHat boxes to see any volumes presented from MSA.

The Redhat O/S sees the MSA hosts ports, but cannot see any new volumes after a re-scan or even after rebooting.

MSA hosts ports are set to PTP

I have rescanned the hosts using 

echo "- - -" > /sys/class/scsi_host/host0/scan

 

I have also rebooted the hosts.

 

Host HBA's can see the MSA hosts ports

There appears to be no multipathing on these hosts, and the original zoning is in correct for the DS4700 as on SAN Switch1 controller A and B aliases have the same wwn.

 

 

Has anyone come accross this issue before?
