Errror out when configuring the Hana replication

Hi all,

We  are setting up the replication system. I followed the steps on the Hana Admin guide.

The configuration on primary was successful.

When I configuring the dr site and ran the step

/usr/sap/HDB/HDB00/exe/hdbnsutil -sr_register –name=hdbopsdr –remoteHost=hana101.opslab.xxxx.com –remoteInstance=00  –mode=syncmem

I got the below error—

hana101:/usr/sap/HDB/HDB00> /usr/sap/HDB/HDB00/exe/hdbnsutil -sr_register –name=hdbopsdr  –remoteHost=hana101.opslab.ariba.com –remoteInstance=00  –mode=syncmem

adding site …

checking local nameserver …

nameserver hana101:30001 not responding.

nameserver is shut down, proceeding …

collecting information …

sending registration request to primary site host hana101.opslab.xxxx.com:30001

updating local ini files …

nameserver hana101:30001 not responding.

done.

The error message is a little vague.  It complains the ‘nameserver hana101:30001 not responding’

  it meant the primary or dr nameserver 30001 not responding?

The primary host info as below(

hana101:30015 stated below, does this mean the primary’s port is on 30015, but the dr try to connect the 30001 port)

hana101:/usr/sap/HDB/HDB00> hdb
