Hardware installation for Synchronous Mirroring and Asynchronous Mirroring | 151
Before proceeding, review the requirements in this section and the zoning example in the figures to
make sure that both switches are correctly zoned. For more information, see
Configurations Overview
Cabling for the intra-site configuration
After both Fibre Channel switches are correctly zoned, set up the intra-site configuration for the
Synchronous Mirroring feature or the Asynchronous Mirroring feature.
About this task
Note: Complete all connections by using Fibre Channel cables of the correct length.
Steps
1. Determine whether you are adding equipment for the Synchronous Mirroring feature or the
Asynchronous Mirroring feature 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 and drive trays
have special power procedures that you
trays. To get specific power-off and power-on procedures, see the installation guide 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 trays or controller-drive trays and the
drive trays is complete on both storage arrays as described in this document.
4. Connect the primary host bus adapter for each host to an available port in zone 1 of switch 1.
The following figure shows the cabling that is described in Step
You can connect the cables to any port in the correct zone of the switch.
