How to use Vxprint to verify that the Rlinks, hostnames and IP addresses for the primary and secondary replication partners match each other in Veritas Storage Foundation for Windows - Volume Replicator Option
Details:
Introduction
In VVR (Veritas Volume
Replicator), if either replication partner contains invalid information,
replication will stop. Each partner may report the other as "disconnected."
Vxprint can be use to verify that the Rlinks, hostnames and IP addresses for hte
primary and secondary replication partners match each
other.
Solution
1. Run the following command on both
sites:
vxprint
-VPl
Note: That is an upper-case V, an
upper-case P and a lower-case L.
This will return results
that are similar to the following:

To confirm that the Rlink names, hostnames or IP
addresses match for both sites, follow these steps:
1. From the primary
vxprint results, locate the following attributes:
Rlink
assoc:
local_host
Note: There are two instances of assoc
found in the vxprint results. These steps refer to the second
instance.
2. Ensure that the values of the attributes that were found
in the primary vxprint results match the following attributes on the secondary
vxprint results:
assoc:
remote_rlink
assoc:
remote_host
The value of
Rlink should match
assoc:
remote_rlink on the opposite partner.
The value of
assoc:
local_host should match the value of
assoc: remote_host. on the
opposite partner.
These values should match in both directions. If there
is mismatch, review the following:
- An IP address mismatch can be
corrected by following the procedure found in this
article:
http://support.veritas.com/docs/245929
- Other mismatches should be resolved by recreating the RVG that contains
the invalid information. A procedure for recreating a secondary RVG can be found
in this
