VNX5200/5500 usermapper migration / VNX decommissioning

Hi all,

The current situation:

2x VNX5500, of which one primary usermapper (VNX1) and the other secondary (VNX2). Also two new VNX5200's (VNX3, VNX4) within the same (management) subnet.

VNX1 reports itself as primary usermapper:

$ server_usermapper server_2

server_2 : Usrmapper service: Enabled

Service Class: Primary

VNX2 is secondary usermapper::

$ server_usermapper server_2

server_2 : Usrmapper service: Enabled

Service Class: Secondary

Primary = 10.0.6.5 (c)

VNX3 and VNX4 are also secondary:

$ server_usermapper server_2

server_2 : Usrmapper service: Enabled

Service Class: Secondary

Primary = 10.0.6.5

But why has VNX2 the "(c)" added to the IP, while the VNX3+4 don't?

VNX2 had a VDM with CIFS shares running on it which are migrated to VNX3.

Reason I ask is because I need to shutdown/decommission VNX2 and want to make sure that I don't break anything when I do so.

Hope someone can shed some light on this, because I was unable to find anything about this in the documentation.

Regards,

Onno.
