Cluster 3.0 and CVM

Question

My configuration is:
) the servers are E6500
) I have 2 nodes (A and B)
) I installed Cluster 3.0, Volume Manager 3.2, CVM and Oracle
I need to make a File System. For example /test. I need to work with this File System in parallel.
Domain A )
/test
Domain B)
/test
with the same disks.
Thanks.

Sounds like you need to create a global filesystem (UFS or VXFS doesn't really matter) and then sym link it to the mountpoint or end location of your choice.
The recommendation would be to do this on public disk not private disks as Cluster 3.0 will hit your interconnects pretty hard when going after storage on the other node (if there is no native connection to the storage)
create the volume on public storage
scsetup
choose 4) Device groups and volumes
choose 2) Synchronize volume information for a VxVM device group
(this assumes you have already registered the volume group with the cluster already)
then you can mkfs/newfs
vi /etc/vfstab (on both sides)
add the mountpoint to /global/somemountpoint
add the global option to the mount options stanza
mount the filesystem
when you roll it into the resource group, and restart the resource group it will come online nicely
If I've forgotten a step please forgive me, I'm walking through this in my head versus reading the doco right now... check out docs.sun.com for more detailed info
