Thanks.
The issue is at the Hardware BCH boot menu level. I know I posted in the HPUX OS group, didn't see a hardware forum.
I did initially have a 11.31 OS installed on the disk at intscsib.0 and it boots. IOSCAN from hpux 11.31 doesn't see the other slot/disk. The disk at intscsia.1 is a 11.11 release of HPUX.
