Symptoms
When attempting to boot from a CD-ROM to install the Solaris[TM] Operating System (Solaris OS) on a new system, that system encounters an error and fails to boot.

For example:

 {8} ok boot cdrom2
SunOS Release 5.9 Version Generic_112233-12 64-bit
Copyright 1983-2003 Sun Microsystems, Inc.  All rights reserved.
Use is subject to license terms.
Cannot assemble drivers for root
/ssm@0,0/pci@1c,700000/pci@3/scsi@5/sd@6,0:b
Cannot mount root on /ssm@0,0/pci@1c,700000/pci@3/scsi@5/sd@6,0:b fstype
ufs
panic[cpu8]/thread=140a000: vfs_mountroot: cannot mount root



Resolution

This problem occurs because the system has the CD-ROM attached to an Ultra3 SCSI Host bus adapter (option X6758), and
the Solaris OS does not have the necessary drivers for that SCSI adapter
incorporated onto the bootable install CD-ROM.


These drivers are not bundled into any Solaris OS release below Solaris 10.

You can find details about the packages that need to be installed 
for this SCSI card in Technical Instruction <Document: 1018123.1> .


You can avoid this problem with one of two possible solutions:


    

  • Boot off of, and install to, an alternate SCSI card that has the requisite drivers bundled into the Solaris OS media that you use to install.
    • 



    

  • Install using a Jumpstart[TM] server that uses a Solaris image
that has had the requisite drivers added to it.  
    • 



Refer to the "StorEdge[TM] PCI Dual Ultra3 SCSI Host Adapter Installation Guide, 816-2156."

 This document is included with the SCSI card when it is sold.
