Fix errors in commands in Sun ILOM
There has been more than one instance when the Sun ILOM was not responsive to commands or were throwing errors. For instance, when you try to run the following command to reset the ILOM
-> reset /SP
Are you sure you want to reset /SP (y/n)? y
Performing hard reset on /SP failed
reset: No such inventory
or when you try to reset the ILOM password, you may get the error “Set: No such object value”

How to find System Serial Number in x86 using ipmitool
As we discussed earlier here, you can find the serial number of a Sun Hardware using the utility “sneep”. However, in Sun X86 systems, you can use the pre-installed tool “ipmitool” to find the system serial number. It is not as straight forward as sneep but still is simpl procedure.
OBP Error: FATAL: system is not bootable, boot command is disabled
When you run any boot command like “boot net” or “boot -s” from the OK prompt (OBP), you may end up with the error
FATAL: system is not bootable, boot command is disabled
Don’t panic!!!
Find Chasis Serial Number using sneep
sneep (Serial Number in EEPROM) is a cool utility for Solaris that can retreive the Chasis Serial Number (CSN) or the Product Serial Number (PSN). This comes real handy when taking inventory or when having to work with Sun Support. sneep can also store useful information like system Assett Tag or Location into the EEPROM which can be retreived later on.

How to find the WWN (World Wide Name) in Sun Solaris
World Wide Name (WWN) are unique 8 byte (64-bit) identifiers in SCSI or fibre channel similar to that of MAC Addresses on a Network Interface Card (NIC).
Talking about the WWN names, there are also
World Wide port Name (WWpN), a WWN assigned to a port on a Fabric which is what you would be looking for most of the time.
World Wide node Name (WWnN), a WWN assigned to a node/device on a Fibre Channel fabric.
How to Enable or Disable a processor in Sun Solaris
In multiprocessor environments, Sun Solaris can allow enabling or disabling Processors. This although is not something that we would do all the time but can come handy when troubleshooting hardware issues.
Sun Solaris has the psradm utility which allows enabling or disabling a Processor on the system. The psradm utility changes the operational status of processors. The legal states for the processor are on-line, offline, spare, Faulted, and no-intr. An online processor processes LWPs (lightweight processes) and can be interrupted by I/O devices in the system.
How to display Processor information in Sun Solaris
Sun solaris has various different utilities to find the processor information on your hardware. Let’s have a look at the different utilities that can display the processor informations and the way they display information.
