Hi! Thanks for the input, Gea!

Every solution works with a different use case idea. In napp-it I am currently working on full appliance redundancy with Z-Raid pool mirroring over iSCSI for a storage and service failover cluster. I have played with the solutions above but in the end I decided to use none of them but use manual target discovery with switchable IP aliases for iSCSI targets to restrict and switchover LUNs and for NFS/SMB failover between the active master storage appliance and the slave. The reason was simplicity and that this works on a lower level that does not rely to Comstar timings and delays. Gea I mainly use FC, and never iScsi, so my control mechanisms are host and target groups, and views. My setups are often that I run clusters with multiple host machines, which runs multiple virtual machines, and if I should map every lu with a new view it would be a hell of a job. It is much easier to just put the wwn in the cluster host group, than to maintain all these views.
