Re: multipathing problem
What PSP are you using? PSP 8.5 or the 8.6? I had a tester Proliant DL 580 G7 and was on PSP 8.5 hooked up to HP StorageWorks arrays -- EVAs and XP (not MSA though). RHEL 5.5 was what I used and HPDM 4.4.1 (HP device multipather kit). Everything was just fine and dandy. Even broke all of my past SwingBench TPC records.

Re: multipathing problem
In this case, the correct configuration of the storage and the multipathing system on the host are very important, otherwise you might cause performance problems for all hosts using the same storage system.
The standard way for the storage system to inform the host about the active/passive state of its ports is called ALUA, or Asymmetric Logical Unit Access. But before the ALUA standard existed, there were various manufacturer-specific protocols for the same purpose. The storage system must be configured to use the same protocol as the host is expecting to see.
There are many possible multipath solutions for RHEL 5: first there is the device-mapper-multipath included in the RHEL 5 distribution, and then there are various proprietary solutions by each storage system manufacturer, e.g. PowerPath from EMC. Which multipath solution are you using, and what's the make and model of your storage?
