SUMMARY: Veritas VM help connecting to an ESS?

From: Tim Bingham <>

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 

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:

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