Are you talking about VA or EVA?
SecurePath is a software for EVA (at least for now). You can share a LUN between different hosts and even OSes, but:
- make sure both OSes can read file system on the LUN otherwise sharing will be useless;
- make sure multiple hosts do not update data at the same time otherwise data can be corrupt;
- w2k hosts may corrupt data 'on the fly' writing its signatures to newly appeared LUNs.
Access to VA LUNs is controlled via security table. Permissions: '0' - no access, 'W' - write access, 'WC' - write access with failover. If VA security is turned on and you create new LUN then this new LUN receives permission '0' by default (no access). Thus you need to update security table and download its new version to VA

Re: VA: Same OS in the same port
In an Oracle Parallel Server environment an LVM volume group is shared to two or more nodes that have write privileges.
It???s a complicated setup that requires special usages of LVM, oracle, kernel parameters and kernel drivers like asyncdsk and the -S option in vgchange / LVM.
In regards to your question, I think it should be posed to the application layer people since there is such a wide disparity between HP-UX and Windows and so much coordination needed from several utilities.
