FWIW, we have a 4500 that had 6TB of emc presented as ~60 devices, the Lus
driver still installed (5.5.1 of Legato, no patches), 2.4.1 of JNI, and worked.
The differences are an ADIC Scalar 1k jukebox (well, 2 on the fabric), and the
fact that this machine controlled it's own robot. Sol 2.6, kernel -21, (now
-23) JNI driver unknown at the moment. Also, the sg driver only has the tapes
the machine can see in /dev/sg. As Veritas Services set up the sg driver with
my tech lead, and not with myself, I cannot speak on any setup-time wizardry
that happened.
