Description
This document provides some pointers on how to identify the various boot devices on Sun Fire[TM] T6300 and T6320 Blade Servers
Symptoms:


  • system will not boot
  • boot fails
  • can't power up
Purpose/Scope:
This
document provides some pointers on how to identify the various boot devices on Sun Fire[TM] T6300 and T6320 Blade Servers


Steps to Follow
Please run the various OBP commands from the ok prompt as outlined below to verify boot devices on your T6300 T6320 blade servers
T6300
– booting from disk

auto-boot?

NOTE: This may
				be the reason you have not booted – you have auto-boot? Set
				to false

				
To enable
				automatic booting, do

				
{0} ok
				setenv
				auto-boot? = true

				
but
				in the meantime, checkout that you can see the boot devices at
				the firmware level

If the device
				alias for disk does not match the device outlined by the
				probe-scsi command, change it as follows:

				
{0} ok
				show-disks
a)
				/pci@7c0/pci@0/pci@2/scsi@0/disk
q) NO SELECTION 
Enter
				Selection, q to quit: a
/pci@7c0/pci@0/pci@2/scsi@0/disk
				has been selected.
Type ^Y ( Control-Y ) to insert it in the
				command line. 
e.g. ok nvalias mydev ^Y 
        
				for creating devalias mydev for /pci@7c0/pci@0/pci@2/scsi@0

{0} ok nvalias
				disk /pci@7c0/pci@0/pci@2/scsi@0/disk@0

Of course,
				this does not check that you have a boot server set up, but at
				least your network has activity. Network ports are shown in the
				Sun System Handbook at :

				
https://support.oracle.com/handbook_private/Systems/SunBlade6000/component.rear.html

				
If this blade
				server was in slot 5, the connection above would be NEM0, port 5

				
Again, if the
				device alias for your network is wrong, change it using 
				

				
{0} ok
				show-nets
a)
				/pci@780/pci@0/pci@1/network@0,1
b)
				/pci@780/pci@0/pci@1/network@0
q) NO SELECTION 
Enter
				Selection, q to quit: b
/pci@0/pci@0/pci@c/network@0
				has been selected.
Type ^Y ( Control-Y ) to insert it in the
				command line. 
e.g. ok nvalias mydev ^Y 
        
				for creating devalias mydev for
				/pci@780/pci@0/pci@1/network@0
{0} ok
