Howto tutorial to get a hard disk serial number from the HPUX server. Learn to obtain disk information using the CSTM command prompt.
Disk serial number is a unique number which is a key identification of disk on the system. While disks are plugged in and online it’s hard to trace their serial numbers physically. Normally serial numbers can be identified on disk which is printed on sticker physically. But if the disk is plugged into the system and currently online it’s hard to observe it physically from all sides and get the serial numbers. In such a condition, we can get serial numbers from OS by running commands. Commands read disk information from disks and extract it for us.
How to get a serial number
Here we are going to see how to get a serial number of the disk which is attached to a server running HPUX. Normally everyone knows diskinfo command to get basic disk information.
# diskinfo /dev/rdsk/c1t1d0
SCSI describe of /dev/rdsk/c1t1d0:
vendor: HP 36.4G
product id: ST336754LC
type: direct access
size: 35566480 Kbytes
bytes per sector: 512
In diskinfo output we get basic information on disk like its vendor, size, product ID, etc. Note that you need to use the raw device in command argument i.e. disk name with rdsk not dsk.
But we are not getting a serial number of the disk here. We will use CSTM to get this information. CSTM is Command-line Support Tool Manager. Its a part of the Online Diagnostic tool which is used for real-time hardware monitoring on HP platforms.
Running cstm will take you to cstm prompt where different commands can be run.
