Connection for the
Highest Availability
Campus
Configuration
NOTE Start the installation at the primary site. Repeat these steps for the secondary
site when instructed to do so.
After the four Fibre Channel switches are correctly zoned, complete this procedure to
set up the highest availability campus configuration for the Synchronous Mirroring
premium feature.
NOTE Complete all connections by using Fibre Channel cables of the correct length.
1. Are you adding equipment for the Synchronous Mirroring premium feature to an
existing storage array environment?
Yes – Stop I/O activity from all hosts before proceeding. Go to step 2.
No – The storage array installation is new. Go to step 3.
ATTENTION Possible hardware damage – DC-powered controller-drive trays and
drive trays have special power procedures that you must follow beyond the procedures
for AC-powered trays. To get specific power-off and power-on procedures, refer to the
topics under the storage array installation for the hardware that you are installing or to
the corresponding PDF document on the SANtricity ES Storage Manager Installation
DVD.
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 connection between all of the controller trays or controller-drive
trays and the drive trays 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. This representation applies
to switch 2 as well.
4. Connect the primary host bus adapter for each local host to an available port in
zone 1 of switch 1.
