SUMMARY: Problems setting up StorEdge 3310 on V240

Problem has been solved. Thanks especially to Will Enestvedt
who responded almost immediately with an answer that pointed
me in the right direction.

My original question;

>The Problem:
>We have a new SUN V240 & a SUN StorEdge 3310 SCSI array. The

The essential problem seems to be that Solaris (including
Solaris 9) is unhappy with more than 64 heads for a drive.
This is totally contrary to what is in the SUN documentation.

For further details see;

The problem is not with "format" but with newfs that seems
incapable of handling the recommended logical drive values.
Fortunately these values can be adjusted in the 3310 RAID
itself. The following worked for me in the 3310 setup;

 "view and edit Configuration parameters" -->
 "Host-side SCSI Parameters" -->
 "Host Cylinder/Head/Sector Mapping Configuration" -->
     "Sector Ranges - 255 Sectors"
     "Head Ranges - 64 Heads"
     "Cylinder Ranges - < 65536 Cylinders"
 Then reset controller.
 On V240 server use;
  "format" -> "type" -> "0 Auto configure"
 Then newfs works perfectly & I have the full RAID5 logical drive
 available as I wanted.
