Chapter 5 First-Time Configuration 5-17
Perform the following steps, which are described in more detail later in this manual,
to set up a DAS loop configuration based on
FIGURE 5-2
.
1. Check the position of installed SFPs. Move them as necessary to support the
connections needed.
You need to add SFP connectors to support more than four connections between
servers and a Sun StorEdge 3510 FC Array. For example, add two SFP connectors to
support six connections and add four SFP connectors to support eight connections.
2. Connect expansion units, if needed.
3. Create at least one logical drive per server, and configure spare disks as needed.
4. Create one or more logical drive partitions for each server.
5. Confirm that the Fibre Connection Option is set to “Loop only.”
Do not use the “Loop preferred, otherwise, point to point” option, which should not
be used for this product.
Caution – Do not use the command, “Loop preferred, otherwise point to point.”
This command is reserved for special use and should be used only if directed by
technical support.
6. Set up to eight IDs on each channel, if needed.
7. Map logical drive 0 to channels 0 and 5 of the primary controller.
8. Map logical drive 1 to channels 1 and 4 of the secondary controller.
9. Map logical drive 2 to channels 0 and 5 of the primary controller.
10. Map logical drive 3 to channels 1 and 4 of the secondary controller.
11. Connect the first server to port 0 of the upper controller and port 5 of the lower
controller.
