AS400 -

It’s 4am – Just finished an AS400 migration from 8830 to DMX – Went swimmingly well. Shut down the system, swing the cables, split the RDF, and boot it back up. Since it’s a direct-attach there is no pesky zoning or masking to deal with. 
AS400′s are an odd beast. The only way to boot them from the Symm is to use a Load Source Emulator, which is to say, a customized Fibre-SCSI bridge that is about the size and shape of a 3.5″ SCSI drive. It slides into the SCSI slot on the AS400 and has a cable sticking out the front of it.
If you ask me, it’s not the most efficient way of doing it, but interesting none-the-less. Then again I’ve never been a big fan of some of the intricacies of IBM hardware, though I *LOVE* AIX as an operating system.
Got a VMS host to do next weekend. *THOSE* are difficult to design around, because they actually depend on the Symmetrix device (Hypervolume or Meta-Head) number being the same. Not just the LUN number. So any binfile has to have the VMS devices in the same locations. –Major pain.
