Replication Setup; Preparing The Network Connection For Replication In A Vls - HP StorageWorks 12000 - Virtual Library System EVA Gateway Manual

replication traffic. However, in multi-node device configurations you must also assign TCP/IP addresses
to every node (matching the static or DHCP mode on node0) in both the source and target VLS devices
in order to balance the replication load across the entire device. (See
for details.) The VLS will automatically balance the active replication jobs across all the nodes that
have an external TCP/IP address configured. The VLS GUI provides the means to configure the
secondary node TCP/IP settings in the "Network Settings" task under Maintenance Tasks on the
Chassis screen (note that the order of the nodes on this screen is not sequential):

NOTE:
If you have any network firewalls between your source and target devices then you must ensure the
firewall is configured to allow traffic on the required ports needed for replication to work:
• The source VLS must be able to contact the target VLS on HTTP port (80), SSH port (22), and ICMP.
• The replication data transfers will use the 'Un-Encrypted Data Transfer Port setting with a default
value of 5570 (which you can modify on the target).

Replication Setup

After preparing your source and destination VLS devices, the following steps configure replication.
See your VLS user guide for details.
