samba - May 2014 - SMB_COM_QUERY_INFORMATION_DISK deprecation effects

One of our customers uses EMC SAN disks.   Newer EMC software no longer supports
the SMB_COM_QUERY_INFORMATION_DISK  command. It was deprecated by Microsoft.

Our SMB scanning no longer works from earlier devices running smbclient 3.0.37.

EMC is going to re-enable the command for a few months but they want us to move
to newer commands.

Is this actually deprecated in the SMB world ?

Can someone tell me what the status of this command is ?

Regards,
Mike

http://msdn.microsoft.com/en-us/library/ee442049.aspx

Even latest smbclient uses this in quite a few commands. As
msdn points out, this would be trivial to replace with
different calls. What is the exact error message the EMC SAN
disk gives you?

With best regards,

Ping me if you need a patch for this. Shouldn't be hard
to change from the old SMB_COM_QUERY_INFORMATION_DISK
SMB1 command to the trans2 version for SMB1 connections.

Shouldn't be a problem when using SMB3 connections.
