I am not able to make any changes on a VMAX using either the SMC, Unisphere for VMax or the symcli.

I am showing a lock number 15 for a config change when I check the locks on the sym.

When I try symcfg -sid xxxx -lockn 15 release -force  I get this message

Lock 15 is held by an internal change session cannot be released

I do not have support on this array anymore, or else I would reach out to EMC support and I am trying to destroy all storage groups  in preparation to power it off and am wondering if there is a way to unlock this lock.

Thanks
