    My original problem was an attempt to get a Sun 420R running Solaris
    7 with Veritas Volume Manager 3.5 and an Emulex LP8000 HBA (with
    current firmware and drivers) to connect to IBM ESS Shark storage.

    During boot, Veritas VM started before the polling of disks was
    finished on the LP8000 and Veritas would declare the unpolled disks
    absent.

    Many different attempts at modifying sd.conf, lpfc.conf, and putting
    delays in the Veritas startup did nothing.

    Replacing the LP8000 with an LP9002L-F2 with the appropriate new
    drivers has fixed the problem. The SCSI driver now polls the HBA much
    sooner in the boot process and the disks are established before
    Veritas VM starts up.

    Thanks to:

    "Markham, Richard" <RMarkham@hafeleamericas.com>
    "Andrew Hay" <adh@an.bradford.ma.us>
    Miguel Demaerel <Miguel.Demaerel@Brussels.sema.slb.com>
    Scott Mickey <mickey@denver.net>
    Reggie Beavers <reggiebeavers@fstha.com>
    "Derrick D. Daugherty" <derrick@tachyon.pointone.com>
    joe.fletcher@btconnect.com
    Travis Freeland <travis@deakin.edu.au>

    They all offered suggestions that helped educate me in the workings
    of the pieces involved in this problem.
