A rather cool utility from EMC is called JCASScript :
https://community.emc.com/docs/DOC-2456
It lets you do stuff from the command line against a Centera. You need a Java Runtime too :

The download from EMC requires a free login. To use it you then do this :
Fire up JCASScript (requires Java runtime) or CASScript.exe
poolOpen ipAddress *can also just use ‘po ipAddress’, also use ‘?’ for help
e.g. po 10.14.97.60
clipOpen contentAddress
e.g. co 2RGPDMAIG8D51eAMOCBFS25BBK2G415357TU510G996D0BM2P833O
clipRawRead contentAddress filename *this Saveset the CDF
e.g. crr 2RGPDMAIG8D51eAMOCBFS25BBK2G415357TU510G996D0BM2P833O c:\myCDF.xml
‘Quit’ to exit.
