Delete Equallogic replication partner

Hello, is there any possibility to forcibly delete replication partner and reclaim delegated space if partner not exist anymore.

Device - Equallogic PS6000xv

Replication was configured with Dell Compellent SCV3020

Here is attempt to reclaim space using CLI:

lgb3> partner show 
Name Received RecvUsed RecvBorrow Delegated DelegUsed DelegBorrow Outbound
Status InboundStatus NASEnabled BlockEnabled SiteType 
---------- -------- -------- ---------- --------- --------- ----------- -------------- -------------- ---------- ------------ ----------
sn255202 0MB 0MB Unknown 2.58TB 0MB 0MB enabled enabled N Y compellent 
lgb3> partner delete sn255202
% Error - Before you can delete a partner, you must pause inbound replication fr
om the partner.
lgb3> partner select sn255202 inbound-pause 
% Error - This operation must be performed using Dell Storage Manager.

Thank you in advance
