Hi all ,

I have an E2900 SPARC IV that has Solaris 10 installed , I am trying to replace solaris 10 with soalris 9/04 , But the installation is giving me an error:

Cannot assemble drivers for root /ssm@0,0/pci@18,700000/pci@4/ide@2/cdrom@0,0:b
Cannot mount root on /ssm@0,0/pci@18,700000/pci@4/ide@2/cdrom@0,0:b fstype ufs
panic[cpu0]/thread=140a000: vfs_mountroot: cannot mount root

has anybody seen this error before or knows what it points to , I have checked the solaris version that i am using for the installation and it supports the current hardware ....

I am having doubts that the problem is related to the fact that the Solaris OS does not have the necessary drivers for that IDE adapter
incorporated onto the bootable install CD-ROM , I have checked that on SUNSOLVE and it says the same but on SUNSOLVE the CD_ROM is a PCI- SCSI3 .

thanks in advance for your help .
Cheers

That is the same problem, the path_to_inst is a bit messed up on that version of the CD. There are a few of options:
1. Use an external SCSI drive
2. Use jumpstart to do the install
3. Use a later release of Solaris 9

Thanks reborg ,

But i am not sure that i got the stuff regarding the path_to_inst thing , From what I know ,this file maps all the devices on the system , But is it supposed to be on the BOOT CD . I assume that every hardware, Platform has a unique path_to_inst ...

Cheers

Yes, more or less. But the one on the boot CD is as generic as possible, and was not capable of providing the CD/DVD drive mapping on 2900's.
