Most things VNX can be exported using Unisphere’s little export icon in the top right hand corner of most if not all dialogs. Disk information would be found under System, Hardware, Disks. You’ll see there is a part number column, but no serial number column in Unisphere for the disks.
To obtain the serial number of the HDD’s in your array, download and install naviseccli on your laptop/storage management server and use the following command…
naviseccli –h <sp-ip-address> -User sysadmin –Password ********* -Scope 0 getdisk –serial
If a security file containing the credentials is already present on the storage management server, then you won’t need to specify the username and password in plain text as shown above.
