The general procedure for creating this configuration follows.
1. Check the position of installed SFP modules. Move them as necessary to support
the connections needed.
2. Connect expansion units if needed.
For information about connecting multiple expansion units, see “Sun StorEdge 3510
FC Array High-Capacity Configurations” on page 43 or “Sun StorEdge 3511 SATA
Array High-Capacity Configurations” on page 57 . For information about connecting
Sun StorEdge 3511 SATA expansion units to Sun StorEdge 3510 FC arrays, see
“Combining Sun StorEdge 3510 FC Arrays and Sun StorEdge 3511 SATA Expansion
Units” on page
67 .
3. Configure cache optimization.
4. Ensure that the fibre connection is set to loop mode.
5. Configure target IDs.
6. Create one Logical Drive for each server and configure spare disks.
7. Map Logical Drive 0 to channels 0 and 5 of the primary controller.
8. Map Logical Drive 1 (if created) to channels 1 and 4 of the secondary controller.
