Host HBA is not logging in on the Symmetrix

I'm experiencing issues while connecting devices to a RHEL5.5 host.

One path is not visible, while the other one is.

- I have mapped the devices to FA 7c1 and 10c1

- Host WWN's are: 5001438004c1d608  ;   5001438004c1d60a

- Host is a c-blade in an enclosure with more hosts that have SAN connection. Blade enclosure should not be an issue.

- emcgrab on the host came back with no issues.

- HBA and FA are zoned properly; Devices over FA 7c1 are visible on the host. Devices over FA 10c1 are not.

- fcping for FA 10c1 reports back:

- Masking is correct:

QLA tools on the host reports back:

- Symmetrix is a DMX3-4500

- Port flag setting of both FA ports are identical. Due to the fact one path is working, this should not be problem.

I am pretty fresh out of idea's of what could be going on here..

Are there things I missing here?
