Question

should show-disks list device path for "Device 2 ( Secondary Master )" ?

Asked by: wboyd

hi,

background: i'm running solaris 9 on a sunblade 100. i've got two internal hdds. my current solaris 9 os is on the primary master hdd. currently only user-defined file systems are mounted on the secondary internal hdd. i am investigating and preparing for possibly installing solaris 10 on a new boot enviroment that i MIGHT create on the secondary internal hdd.

i have spent the last 2 hours searching google and ee for answers to the following questions. please, does anybody here know the answers? (see below for details of what i DO know):

1. probe-ide reports my 2nd internal hdd as ""Device 2 ( Secondary Master )". what do i have to do to make show-disks list a device path for my 2nd internal hdd?

2. devalias reports aliases for 5 disks. am i correct in assuming that these are only "reserved" aliases and that they don't necessarily map to actual devices?

assuming the alias "disk1" and the device path "/pci@1f,0/ide@d/disk@1,0" do actually map to "Device 2 ( Secondary Master )"; i expect that either one or the other of the following commands would result in booting from "Device 2 ( Secondary Master )":

     ok boot disk1
     ok boot  /pci@1f,0/ide@d/disk@1,0


3. but why does "ok .properties" on "/pci@1f,0/ide@d/disk@1,0" report the name as "disk" instead of "disk1" (see below)?

4. what non-destructive command would prove that the alias "disk1" and the device path "/pci@1f,0/ide@d/disk@1,0" actually maps to "Device 2 ( Secondary Master )"?

thanks in advance for your help

NOTE: i don't have an os on the 2nd internal hdd YET. i am only preparing for when i do eventually install an os on that drive. so you would be wasting your time replying with answers like, "just try it and see". please, try to answer the specific questions that i have asked and ONLY those questions.

this is what i know:

   ok probe-ide
   
        Device 0      ( Primary Master )
                   ATA Model: ST320011A
   
        Device 1      ( Primary Slave )
                   Removeable ATAPI Model: LTN486S
 
        Device 2      ( Secondary Master )
                   ATA Model: Maxtor 6Y120P0
   
       Device 3            ( Secondary Slave )

For OBP, device setting details please read the Sun blade 100 manuals:
http://www.sun.com/products-n-solutions/hardware/docs/Workstation_Products/Workstations/Sun_Blade_Workstations/Sun_Blade_100/index.html

To install a different version of OS in your 2nd Hd, you can simply, boot uo from CDROM or boot server, select the 2nd DH to install.

When you want to boot from the 2nd HD, at OPB, tupe in:
boot disk1

>...please, try to answer the specific questions that i have asked and ONLY those questions.

Since the OBP seeting can be change by anyone (redefined the values etc).

To verify the device name is correct or not, you can do it the the Solaris commandline.

type in:
prtconf –vp | grep -i disk1

then compare with the out put:
ls -al /dev/dsk/c0t2d0s0

PS: you can use format to find out the device name for your 2nd HD
replace c0t2d0 with the real device you have.

eg, here's the out put off my Sun Blade 100:

# prtconf -vp | grep disk                
            disk-write-fix:  
            name:  'disk-label'
        bootpath:  '/pci@1f,0/ide@d/disk@0,0:a'
        diag-device:  'disk net'
        boot-device:  'disk:a disk:b net'
        disk:  '/pci@1f,0/ide@d/disk@0,0'
        disk3:  '/pci@1f,0/ide@d/disk@3,0'
        disk2:  '/pci@1f,0/ide@d/disk@2,0'
        disk1:  '/pci@1f,0/ide@d/disk@1,0'
        disk0:  '/pci@1f,0/ide@d/disk@0,0'
                name:  'disk'
                compatible: 'ide-disk'

ls -al /dev/dsk/c0t2d0s0
lrwxrwxrwx   1 root     root          38 May 15  2002 /dev/dsk/c0t2d0s0 -> ../../devices/pci@1f,0/ide@d/dad@2,0:a

   my disk c0t2d0 is disk2 in my OBP.

   Note: the OBP device pathname format is:
             driver-name@unit-address:device-arguments
             
              and the device alias can set by anyone has access to the OBP.

1. good question, but not relevant.  Use the info that Yuzh provided to figure it out.

2. Yes

3. disk and disk1 are normally, but not always set to the same disk.  If someone else has palyed with the system, they could be set to anything, including invalid settings.

4. boot disk  (if it boots then it is point at your disk with the os otherwise it is the other disk)
boot disk1  (if it boots then it is point at your disk with the os otherwise it is the other disk)
boot disk2  (if it boots then it is point at your disk with the os otherwise it is the other disk)
