Note: When device ID information from the source device is assigned by NDM to the target device, 32 is added to the
port numbers for the target FA ports. This is done so that the host will not see the same device ID being accessed
through the same director and port when the new paths are configured. In the above example, the devices are mapped
to ports 28 and 29, which are displayed as ports 60 and 61. This does not apply to PP 6.2 and above where the ports
are displayed correctly.
LIST THE NDM SESSIONS
There are different options that can be used to list the NDM sessions. Adding
–v to the symdm list command provides
more detail about the session.
C:\>symdm -sid 3184 -sg lcseb246_sg list -v
Symmetrix ID : 000195703184
Storage Group : lcseb246_sg
Source Array : 000195703184
Target Array : 000197800129
Migration State : CutoverReady
Total Capacity (GB) : 200.0
Done (%) : N/A
Source Configuration: OK
{
Storage Groups (1) : OK
Masking Views (1) : OK
Initiator Groups (1): OK

}
Target Configuration: OK
{
Storage Groups (1) : OK
Masking Views (1) : OK

Port Groups (1) : OK
}

Adding -detail to -v provides information broken down by Storage Group, Masking View, Initiator Group, and Port Group
from each array as well as a listing and status of the device pairs:
C:\>symdm -sid 0129 -sg lcseb246_sg list -v -detail
