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.

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.

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.

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.
