Several people pointed out very politely that I meant "stair-stepping" not "door-st[oe]pping".. Sigh. I'm sure that's what I typed all along, isn't it?:-) Adam and John both correctly pointed out that Sunsolve document 40646 discussed the "stair-step" phenonemon during booting, this is caused by corrupted "serial" entries in /etc/path_to_inst. I'm not quite sure why the entries were corrupted - given that the server was freshly jumpstarted, the automated install had only just created /etc/path_to_inst! - but this was undeniably the cause. The sunsolve document suggests two remedies: 1. get solaris to rebuild /etc/path_to_inst by moving it sideways and rebooting with "boot -a" or "boot -ar". 2. hand editing the /etc/path_to_inst file, fixing the broken entries. I tried (1), ran into some further problems with it failing to look up the /dev and /devices entries for the root disk and not regenerating /etc/path_to_inst, backed out, and then successfully tried (2), fixing the problem completely. In particular, the initial "serial" entries (grep serial /etc/path_to_inst) were: "/pci@1f,0/isa@7/serial@0,3f8" 0 "su" "/pci@1f,0/isa@7/serial@0,2e8" 3 "su" "/pci@1f,0/pci@1,1/isa@7/serial@0,3f8" 1 "su" "/pci@1f,0/pci@1,1/isa@7/serial@0,2e8" 2 "su" "/pci@1e,600000/isa@7/serial@0,3f8" 4 "su" "/pci@1e,600000/isa@7/serial@0,2e8" 5 "su" and I replaced them with: "/pci@1f,0/isa@7/serial@0,3f8" 0 "su" "/pci@1e,600000/isa@7/serial@0,3f8" 1 "su" "/pci@1e,600000/isa@7/serial@0,2e8" 2 "su" [i.e. kept the first, lost the 2nd-4th, and edited the "4","5" column to read "1","2" respectively..] and rebooted, all traces of stair-stepping are now gone, and tcsh doesn't even whine about "no job control" either:-) So, once more sun-managers rides to the rescue! Thanks very much everyone! [Perhaps if I'd managed to type "stair-stepping" into google/sunsolve I might have got somewhere without asking the list:-)] cheers, duncan --------------------------------------------------------------------------- Duncan C.
