You mean like a cluster filesystem? Concurrent access from 2 nodes to a shared disk/LUN?
You can't do that with Serviceguard and LVM.
You can do it with Serviceguard and the cluster version of VxVM and VxfS. It's packaged up as the Serviceguard Storage Management Suite Cluster Filesystem:

For sharing archive logs, the only other option to a CFS is NFS mounts using the HA NFS toolkit (which you will already have if you're using MCOE)
Either that or you ditch Serviceguard completely and use the Oracle clusterware stack with ASM - though I wouldn't reccomend that approach.

Jose,
Ok a couple of extra points:
1. The SGeRAC product does not in itself contain the cluster filesystem components - they are an additional piece of software with additional cost.
2. What I missed in your earlier responses was that you were on 11iv1. Unfortunately the CFS solution is for 11iv2 only as it relies on newer versions of VxVM which were never ported back to 11iv1.
This limits your choices a bit. Either:
1. Stick with NFS mounts. This can be done ina HA fashion if you use the latest version of the NFS automounter and are careful about mount options with NFS (the Serviceguard extension for SAP manual is a good source on how to configure NFS in a HA fashion)
2. Go to a complete Oracle stack with ASM and no Serviceguard. This probably costs less than option 3 but has quite a few drawbacks, not least the fact that:
i) you have to provide you're own multi-pathing solution (such as secure path or powerpath). LVM PVLinks aren't much use as ASM works on raw disks.
ii) You have to provide youre own network resiliency using APA
iii) You can't really provide HA for anything except your Oracle DB
iv) The Oracle clusterware is entireley in user space, and I believe (in my subjective opinion) not as mature or reliable as Serviceguard.
3. Upgrade to 11iv2 and purchase the CFS software. This would mean trading in your existing MCOE for the MCOE with CFS (T2797BA). The software isn't cheap though, but like I said you should be able to get a trade-in for your MCOE and SGeRAC licenses.
