Dredging up a conversation from last year. I know in theory the horse is dead, but I think I might have seen a twitch.

The 'Implementing IBM Tape in Unix Systems' redbook talks about dynamic load balancing (per tape open) across all available HBAs. This leads me to think that, if I have 4 HBAs devoted to tape traffic, I want to have each one zoned with all my (dual ported, natch) tape connections. This sounds sane, so far. But then I do math and get 8 drives * 2 ports * 4 HBAs = 64 rmt devices for my 8 drives. I know that instAtape will collapse those down so I only need to use the -PRI devices for e.g. paths. but it just makes me feel odd to have so many. So, I'm wondering: Am I being silly? Just go ahead and do it? Should I be zoning some of the HBAs for port 0 on the tapes, others for port 1? I have an inclination, which I am working to stifle, to have this neat spirograph of a venn diagram so that HBA 1 is connected to odd ports of even tapes, and HBA 2 is connected to ... - Allen S. Rout - Maybe that was just maggots?
