[Users] CLI: can't attach storagedomain

[David Li]

Hi,
I have an iso domain created during engine setup. But I can't attach it to the 
datacenter in cli.

oVirt shell (connected)]# create storagedomain --name 
"fc16-lid-engine_iso-domain" --datacenter-identifier 
"ac2690e4-72b2-11e1-882d-000c29bf47ca"
unknown error: 
status: 400
reason: Bad Request
detail: [Cannot attach Storage Domain.]


Any ideas?
