How to create a Metro Mirror or Global Mirror partnership
over Ethernet ports using IPv4 and IPv6 addressing, how to create
a Remote Copy port group, and best practices.
Creating the partnership
To create a remote-copy partnership over an IP
connection, complete these steps:
- Configure VLAN tagging by completing these steps:
- In the
management GUI, select .
- Right-click the port on which to configure the VLAN and select .
- On the Modify VLAN page, select to enable VLAN for either IPv4 or IPv6
connections that are part of the remote-copy group.
- Enter the VLAN tag and select whether to use the same VLAN tag for the failover port.
- Click Modify.
- Define the remote-copy groups on both the local and partner systems.
- On the primary system, select .
- Right-click the port on which you configured the VLAN tag, and select Modify Remote
Copy.
- Depending on the type of IP connection you are using, select the remote-copy group to associate
with the port.
- Click Modify.
- Repeat these steps on the remote system, ensuring that you use the same remote-copy group to
ensure connectivity between the two systems.
- Configure IP partnerships on the local system in the management GUI by
completing these steps:
- Select and select Create Partnership.
- On the Create Partnership panel, select IP.
- Enter the following information to configure the partnership:
- Partner System IP Address
- Enter the IP address of the other system within the remote-copy partnership.
- Link Bandwidth
- Enter the amount of bandwidth that can be used for the IP connection between the systems within
the partnership.
- Background Copy Rate
- Enter the maximum percentage of the link bandwidth that can be used for background copy
operations.
- Partner System's CHAP Secret (Optional):
- Specify the CHAP secret for the partner system if you plan to use Challenge Handshake
Authentication Protocol (CHAP) to authenticate connections between the systems in the partnership.
- Compression enabled
- Select this option if data on the local system is compressed before it is sent to the partner
system. To fully enable compression in an IP partnership, each system must enable compression.
- Configure IP partnership on the partner system in the management GUI by completing these steps:
- Select and select Create Partnership.
- On the Create Partnership panel, select IP.
- Enter the following information to configure the partnership:
- Partner System IP Address
- Enter the IP address of the other system within the remote-copy partnership.
Note: This is the
system that you configured in step 2.
- Link Bandwidth
- Enter the amount of bandwidth that can be used for the IP connection between the systems within
the partnership. Use the same value that you specified in step 2.
- Background Copy Rate
- Enter the maximum percentage of the link bandwidth that can be used for background copy
operations. Use the same value that you specified in step 2.
- Partner System's CHAP Secret (Optional):
- Specify the CHAP secret for the partner system if you plan to use Challenge Handshake
Authentication Protocol (CHAP) to authenticate connections between the systems in the partnership.
Use the same value that you specified in step 2.
- Compression
- Select this option if data on the local system is compressed before it is sent to the partner
system. To fully enable compression in an IP partnership, each system must enable compression.
