Hi George, I wanted to make sure that the information I was giving you was as accurate and current as possible. This prompted me to have one of my guys to check it out in the Veritas Documentation, before I sent out the note. The documentation for version 3.3, clearly states that the default logical blocksize for Veritas is 1024 bytes. Your take about the automatic scale-up for very large files may also be true.
Regardless, I think the point I was trying to drive home is simple - You need to ensure "equality" of db_block_size and the filesystem block size. The default value may change across releases and that is not something that we have control over or should depend on. And I am very glad to hear that your environment adheres to that. Good for you!!!
