Hi,
In my simple experiment, i connected to a SHAREDFS storage server
and then created a data domain
But the createStorageDomain failed with code 351, which just says "Error
creating a storage domain".
How to find out what the real reason behind the failure.
Surprisingly, the domain dir structure does get created, so looks like
it worked, but still it gives
failure as the return result, why ?
