Trying to setup SanCopy between 2 VNX arrays
Ive been reading a doc (http://finland.emc.com/collateral/TechnicalDocument/docu10319.pdf) and trying to follow the steps to setup sancopy.
Im doing this using naviseccli in order to document the exact steps/sequence needed, while using the GUI to monitor and review what im doing.
I setup the zoning as recomended, with VNX1 SP's connected to VNX2 SP's.
Switch 1:
| zone: SCZ1 | vnx1a2; vnx2a2 |
| zone: SCZ2 | vnx1a2; vnx2b2 |
| zone: SCZ3 | vnx1b2; vnx2a2 |
| zone: SCZ4 | vnx1b2; vnx2b2 |
Switch 2:
| zone: SCZ1 | vnx1a3; vnx2a3 |
| zone: SCZ2 | vnx1a3; vnx2b3 |
| zone: SCZ3 | vnx1b3; vnx2a3 |
| zone: SCZ4 | vnx1b3; vnx2b3 |
What im seeing is the following (just 1 array shown, the other looks similar):
Im not sure if this is good or bad, given the yellow-warning signs on the left.
The doc sais you have to add the sancopy connections to a storage group, but im not finding the naviseccli command structure for doing that task. It would be the equilivant of this GUI except as a CLI command.
Can anyone point me to the correct naviseccli command for doing this task?

Hello,
Check the navicli manual: docu47580_VNX-Command-Line-Interface-Reference-for-Block-5.33.pdf
Page 495:
Connecting SAN Copy ports to storage groups
Note
Each SAN Copy port acts like a host initiator and, therefore, can connect to only one
storage group at a time in a storage system.
In order for the LUNs to be accessible to the SAN Copy ports, you must connect the SAN
Copy ports to the storage groups in which the LUNs reside. When connecting to the
storage group, SAN Copy lets you select all available SP ports with valid connections to
the storage group, or it lets you select specific ports.
If all participating logical units of a remote storage system already belong to the same
storage group, you can connect SAN Copy ports to the existing storage group. However, if
the logical units belong to different storage groups, we recommend that you create one or
more new storage groups, place the logical units in these storage groups, and then
connect SAN Copy ports to them. This is the only time we recommend placing the same
logical unit in more than one storage group.

naviseccli -h 10.23.66.19 storagegroup -setpath -gname ns120-vnx-migration -hbauid 50:06:01:60:BC:E0:1C:06:50:06:01:63:3C:E0:1C:06 -sp a -spport 0
in this instance storage group "ns120-vnx-migration" already exists. This storage group will be used for placing SANCopy target devices.

I found the SAN copy white paper really helpful when I was setting up sancopy.
