O.k. Now here's a big rub...
On the NSRs (FC-SCSI bridges, sometimes called "Crossroads" switches
since they seem to be the only company in the country (world?) who makes
them, everyone else -including HP - just rebadges them, and maybe tweaks
the firmware a bit), if you're remapping SCSI id's, make sure that each
MAP starts with LUN 0. Apparently, VMS can't handle it if, for example,
the first NSR presents LUNs 0-4 and the second presents 5-whatever.
I kinda wish you had elected to hold SYSMAN IO AUTOCON until after you
had resolved the visibility problem. The only way to clear the VMS data
structures it (and FIND_WWID) populates is to reboot the entire cluster.
Note that if you want, before your next reboot, you can change the MGA
device units numbers to any you wish - you're not stuck with what SYSMAN
arbitrated. However, if you've already configured other software to use
the existing device units, well, you know how that stuff kinda
snowballs...
