Hardware installation for Synchronous Mirroring and Asynchronous Mirroring | 121
Complete all connections by using Fibre Channel cables of the correct length.
Note:
Steps
1. Determine whether you adding equipment for mirroring to an existing storage array environment.
• If so, stop I/O activity from all hosts before proceeding. Go to Step
• If not, this is a new storage array installation. Go to Step
Attention: Possible hardware damage – DC-powered controller-drive trays have special
power procedures that you
specific power-off and power-on procedures, see the installation instructions for your storage
array.
2. Turn off the power to all storage arrays, hosts, Fibre Channel switches, and any other equipment
in the storage array environment.
3. Make sure that basic cabling between all of the controller-drive trays and the drive trays on both
storage arrays is complete.
Note: Depending on which site is being configured, switch 1 represents switch 1A for the
primary site and switch 1B for the secondary site.
You can connect the cables to any port in the correct zone of the switch.
Note:
4. Connect the primary host bus adapter for each host at this site to an available port in zone 1 of
switch 1A.
The following figure shows the cabling that is described in Step
121.
5. Connect the secondary host bus adapter for each host at this site to an available port in zone 2 of
switch 1A.
The following figure shows connections between a host bus adapter and a Fibre Channel switch.
