Presenting virtual disk to multiple hosts
Probably stupid question but was wondering if it is at all possible to have one virtual disk attached to two hosts, with both hosts being able to read/write.
We have an HP EVA attached to 2 hosts and ideally would like to have a 'file system' accessible to both. Do not want to go down the NFS route. Is additional software required?
Thanks
Fiona

Re: Presenting virtual disk to multiple hosts
Unfortunately, most operating systems simply cannot do this, because the lack this required components for concurrent disk access. For some operating systems it is possible to buy third-party add-on software which provides this feature.

Re: Presenting virtual disk to multiple hosts
The next release of HP-UX will incorporate a much improved Veritas features (4.0 releases of VxVM, VxFS, CVM, and Cluster) although at the current release that is bundled/integrated with VxVM -- some "cluster" volume manager functionality is already present.
