Meant to send this out to the entire list, so others could hear what Edison
has to say, as well.

Subject: Re: createAsync Question
To: Edison Su <edison...@citrix.com>
Ah, I remember our discussion about that more now.
Here is what my createAsync currently looks like (after I read your e-mail):
@Override
public void createAsync(DataObject data,
AsyncCompletionCallback<CreateCmdResult> callback) {
String iqn = null;
String errMsg = null;
if (data.getType() == DataObjectType.VOLUME) {
try {
// just create a SolidFire volume and return IQN
iqn = createSolidFireVolume((VolumeInfo)data);
} catch (StorageUnavailableException e) {
s_logger.debug("Failed to create volume
(StorageUnavailableException)", e);
errMsg = e.toString();
} catch (Exception e) {
s_logger.debug("Failed to create volume (Exception)", e);
errMsg = e.toString();
}
}
else {
errMsg = "Invalid DataObjectType (" + data.getType() + ")
passed to createAsync";
}
// path = iqn
// size is pulled from DataObject instance, if errMsg is null
CreateCmdResult result = new CreateCmdResult(iqn, errMsg != null ?
null : data.getSize());
if (errMsg != null) {
result.setResult(errMsg);
}
callback.complete(result);
}
Do I have to update any DB table at this point now that my volume has been
created on the SAN?
Thanks!!
