I was having problems booting a cluster member; got a "cb_open: failed"
message (see below).

Turns out that the fiber-switch to the disk-array must have been very
confused and so the machine was unable to find its root disk ("sho dev"
at the "P00<<<" prompt should show the boot disk - something like dga*
in my case but it wasn't there). Logging in to the HSG80 showed that all
the connections were offline ("sho con") and at least 1 light was off on
the fiber-switch.

Luckily a hardware engineer from Compaq came in this morning for another
problem (which was likely tied-in to the event which triggered all
this). He suggested rebooting everything and it looks like rebooting the
fiber-switch was the key. Now the cluster members boot (but of course
there's another problem which may make it into another question).

Only one taker so far - thanks to Uwe Lienig.
