re SAN, Heterogenous environments, Backups
John, re your suggestion to ask the vendors about the Veritas File System, both Sun and Hitachi said that the Veritas VxFS filesystem is not portable across servers. Thus a Sun server cannot read an VxFS file system on an HP server. We cannot, therefore, backup a SAN shadow-image of a Veritas Volume holding VxFS for HP to a Sun backup server as the Sun server cannot mount the file system.

RE: SAN, Heterogenous environments, Backups
John, I forwarded your suggestion, together, with more information on the Veritas Foundation Suite to the team negotiating the hardware solution with the vendors [my involvement came in as I was allowed to us about how database backups in a SAN were to be done].
