SUMMARY: Problems with Solaris 8, RAID Manager 6.22 & SBU/LGT SCS I Passthru Drivers

I've researched several fixes and workarounds as follows:

- disable rdriver/rdac during Legato Setup and 3P software install that does
an add_drv, etc.
- modify lus.conf so that it does binds to a known lun/path
- modify /kernel/drv rdriver.conf and rdnexus.conf for what are actually
present (bus/luns.controllers..)

There were also several references on SunSolve relating to lus interacting
with RM...

Thanks to some that recommended some measures...
