From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Colb, Andrew Sent: Tuesday, April 24, 2007 2:14 PM To: veritas-ha@mailman.eng.auburn.edu Subject: [Veritas-ha] Naming conventions for VCS; VCS style guide? All, We are about to initiate and upgrade several VCS clusters. The plan for these upgrades will enable us to build/test in parallel with existing production clusters and to revisit our traditional cluster nomenclature and naming conventions. Our configuration has a five-node production Solaris Veritas cluster at our headquarters; we are building a four-node equivalent at our warm business continuity site (active data replication). The two sites are connected by a point-to-point DS-3; firewall rules allow one site to see and interact with the other. Our current VCS nomenclature is pretty much ad hoc. The new VCS nomenclature would have the following structure: stem_object## where stem is either a functional name (e.g., db) or a singular, universal name (e.g., prod), object is dg or sg, and ## is a zero-padded numeric for serialized differentiation. Question 1: Can we use identical names for VCS diskgroups and service groups at the two sites (HQ and Continuity) simultaneously? Host names will, of course, be different. The clusters will have different cluster IDs. If we do use identical names, will that create a problem if we move on to Global Cluster Option and/or to VVR? For example, if we have a service group named "db_sg01" in both our headquarters cluster and our business continuity cluster, will VCS complain? JS>> Absolutely. No issues with identical names in separate clusters Question 2: Is there an advantage in Veritas management/administration if all the stem names are the same? That is, if we replace existing stem names such as db, auth, appsrv, etc with a single universal name such as "prod", will we be gaining anything in exchange for giving up the functional association? JS>>> Cluster Management console either has or will be providing a search function, so it all depends on how you want to search :-) Thanks in advance for any discussion, advice, ideas, guidance, and warnings, Andy Colb Investment Company Institute
