Document ID: 1125 SYNOPSIS: Installing on SCSI drive of system with both IDE and SCSI DETAIL DESCRIPTION: How to install Solaris 2.1 for x86 on the SCSI drive on a system with both IDE and SCSI drives. NOTE: It is more convenient to install x86 on the primary drive, which is the IDE hard drive, on a system with both IDE and SCSI drives, since the x86 boot manager will allow you to choose which Operating System, DOS or Solaris for instance, to boot from during the boot process. However, if you must install x86 on the SCSI, for performance reasons or else, there is no problem except you need to apply the following steps to workaround a known bug we currently have on the Solaris 2.1 for x86. Please note this is fixed on releases 2.4 and above. The only drawback to this configuration is that, you need to either boot from the x86 boot diskette or configure CMOS to temporarily disable IDE hard drive (Driver C or D as 'Not Installed') to boot x86. SOLUTION SUMMARY: Follow these steps: 1. Install x86 on the SCSI hard drive. During installation, please note the IDE hard drive is referred as 'c0t0d0p0', and SCSI as 'c1t0d0p0'. 2. Once installation is done, reboot the system. From the secondary subsystem screen, you'll notice the boot path is set incorrect. It is set to the --ata@--, which is for the IDE controller, not the SCSI one. It will prompt for "(b)oot or (i)nterpreter:" Enter i for interpreter. 3. Then, type the following: > setprop boot-path /isa/aha@330,0/cmdk@0,0:a Then Ctrl-d to resume boot. Now it should boot with no further interaction. 4. Once you are logged in, edit the /etc/bootrc file, and change the incorrect boot-path permanently. setprop boot-path /isa/aha@330,0/cmdk@0,0:a NOTE: The above boot-path is an sample example for Adaptec 154x controller card. You should use your own boot-path based on your SCSI controller. I have listed some of the sample boot-path for various controller cards we support: M/B Type Boot-path ---- ---- --------- ISA AHA-154x setprop boot-path /isa/aha@330,0/cmdk@0,0:a with I/O base 330 EISA AHA-154x setprop boot-path /eisa/aha@330,0/cmdk@0,0:a with I/O base 330 EISA AHA-174x setprop boot-path /eisa/eha@4000,0/cmdk@0,0:a in slot 4 ISA DPT-2011 setprop boot-path /isa/dpt@170,0/cmdk@0,0:a with I/O base 170 EISA DPT-2012 setprop boot-path /eisa/dpt@2c88,0/cmdk@0,0:a in slot 2 DATE APPROVED: 10/10/95 KEYWORDS: Install SCSI drive IDE boot OS RELEASE: 2.1
