You might need to identify the devices on the system to determine what are the appropriate devices to boot from.
Before you can safely use the probe commands to determine what devices are attached to the system, you need to do the following:
Change the PROM auto-boot? parameter to false.
ok setenv auto-boot? false |
Issue the reset-all command to clear system registers.
ok reset-all |
You can view the probe commands that are available on your system by using the sifting probe command:
ok sifting probe |
If you run the probe commands without clearing the system registers, the following message is displayed:
ok probe-scsi This command may hang the system if a Stop-A or halt command has been executed. Please type reset-all to reset the system before executing this command. Do you wish to continue? (y/n) n |
Identify the devices on the system.
ok probe-device |
(Optional) If you want the system to reboot after a power failure or after using the reset command, then reset the auto-boot? parameter to true.
ok setenv auto-boot? true auto-boot? = true |
Boot the system to multiuser mode.
ok reset-all |
The following example shows how to identify the devices connected to an Ultra 10 system.
ok setenv auto-boot? false auto-boot? = false ok reset-all Resetting ... Sun Ultra 5/10 UPA/PCI (UltraSPARC-IIi 333MHz), No Keyboard OpenBoot 3.15, 128 MB memory installed, Serial #10933339. Ethernet address 8:0:20:a6:d4:5b, Host ID: 80a6d45b. ok probe-ide Device 0 ( Primary Master ) ATA Model: ST34321A Device 1 ( Primary Slave ) Not Present Device 2 ( Secondary Master ) Removable ATAPI Model: CRD-8322B Device 3 ( Secondary Slave ) Not Present ok setenv auto-boot? true auto-boot? = true |
Alternatively, you can use the devalias command to identify the device aliases and the associated paths of devices that might be connected to the system. For example:
ok devalias screen /pci@1f,0/pci@1,1/SUNW,m64B@2 net /pci@1f,0/pci@1,1/network@1,1 cdrom /pci@1f,0/pci@1,1/ide@3/cdrom@2,0:f disk /pci@1f,0/pci@1,1/ide@3/disk@0,0 disk3 /pci@1f,0/pci@1,1/ide@3/disk@3,0 disk2 /pci@1f,0/pci@1,1/ide@3/disk@2,0 disk1 /pci@1f,0/pci@1,1/ide@3/disk@1,0 disk0 /pci@1f,0/pci@1,1/ide@3/disk@0,0 ide /pci@1f,0/pci@1,1/ide@3 floppy /pci@1f,0/pci@1,1/ebus@1/fdthree ttyb /pci@1f,0/pci@1,1/ebus@1/se:b ttya /pci@1f,0/pci@1,1/ebus@1/se:a keyboard! /pci@1f,0/pci@1,1/ebus@1/su@14,3083f8:forcemode keyboard /pci@1f,0/pci@1,1/ebus@1/su@14,3083f8 mouse /pci@1f,0/pci@1,1/ebus@1/su@14,3062f8 name aliases |
