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.
Sneep searches for the serial number in several data sources, including the system eeprom, platform-specific hardware-based sources, the configuration files for the Sun “explorer” and “Configuration Service Tracker (CST)” tools, and its own backup file. This order of searched can be altered.
Display Serial Number
To simply display the serial number run sneep with no arguements
# sneep
0011223344
To display the serial number and its associated tag in the EEPROM and infact all stored Tag/Value pairs.
# sneep -T
“ChassisSerialNumber” “0011223344”
Store Information in EEPROM
To store information into the EEPROM like the asset tag use the “-t” to set the tag name and the “-s” option to set its value as below:
# sneep -t “AssetTag” -s 001234
To display all information
# sneep -T
“AssetTag” “001234”
“ChassisSerialNumber” “0011223344”
