Hi David et al, appreciate that you consider using Sun Cluster :)
You should also have a look at the Sun Cluster 3.1 - 3.2 With Network-Attached Storage Devices Manual for Solaris OS: http://docs.sun.com/app/docs/doc/819-3024?a=expand As also described within the document you cite, there are two aspects implemented through the NTAPclnas package provided by NetApps: - Failure Fencing - Quorum So even if you decide to use the Quorum Server instead of using the NetApp NAS device as quorum, there is still the need for failure fencing. In the Sun Cluster case you do not need an agent for the NFS mounts. I would be curious to know what the agent does in the VCS case. In the Sun Cluster case, as described within http://docs.sun.com/app/docs/doc/819-3024/ezlri?a=view, there is only an entry in the /etc/vfstab necessary for each node that should mount the nfs share. The nfs mount is then done at node boot or when dynamically added, you can mount it manually. There are required mount options if you use Oracle RAC. Now the clnasdevice command also listed within the steps makes sure that the configured NFS share is considered with failure fencing. If a node fails or looses quorum, then the failure fencing mechanism performed through NTAPfence makes sure that only the node(s) are able to access the nfs share, which are a valid member of the current cluster. Access by other nodes is denied. So you can see the cluster actually does control the nfs mount access through the fencing mechanism. clnasdevice is used to register the share both, with the cluster and with the NAS device, NTAPclnas is used by the fencing algorithm upon reconfiguration. Hope this helps, let us know if my explanation was too confusing :) Greets Thorsten David Blackburn wrote: > Hi. > > I currently work at a company that only uses VCS atm and I am currently > looking to implementing SC.
