Multi path on Solaris 8 and EVA 5000 vcs 4.044 using FCA2257p

[BR883300]

Hi
I'm trying to connect an Sun Fire V280R to our EVA 5000 Array. VCS is 4.044. Solaris is ver 8.
HBA's are FCA2257P.
I cant get Suns MPxIO solution to work in this configuration. I've installed SUN SFS 4.4.11. HBA driver ver 4.20.
I have scrolled through a lot of different information on this, and now i'm not sure that this is a supported solution.
Does anybody know if my setup is supposed to work??
In some documents I can read that Suns MPxIO only works with Suns original HBA's, but in other documents FCA2257 is also mentioned.
If it's not supported, how do I then get multipath support?
Do I have to change my HBA's or do I have to switch to Veritas DMP og SecurePath?
Any help appreciated.
