To configure synchronous mirroring, you create a mirrored
pair that includes a primary volume on the local array and a secondary
volume on the remote array.
Before
you create a mirrored pair, meet the following requirements for
SAN Manager :
Also be sure to meet the following requirements
for storage arrays:
- The two storage arrays
you plan to use for mirroring are discovered in SAN Manager .
- Each storage array must
have two controllers.
- Each controller in both the
primary array and secondary array must have an Ethernet management
port configured and must be connected to your network.
- The storage arrays have a minimum firmware version of 11.50. (They
can each run different OS versions.) Mirroring setup is different
when using SAN Manager 4.1 and earlier versus 4.2 and later, as well
as System Manager 11.60.1 and earlier vs 11.60.2 and later.
If your controllers are using System Manager 11.50–11.60.1,
select the initiator array and click Launch to open the browser-based
System Manager and configure mirroring from there.
If your controllers are using System Manager 11.60.2 or later,
mirroring configuration is performed entirely from SAN Manager 4.2
or later.
- You must know the password
for the local and remote storage arrays.
- Your local and remote
storage arrays are connected through a Fibre Channel fabric.
- You have created both
the primary and secondary volumes that you want to use in the synchronous
mirror relationship.
The process
to create synchronous mirrored pairs is a multi-step procedure.
