5-14 Sun StorEdge 3000 Family Installation, Operation, and Service Manual • March 2004
Perform the following steps, which are described in more detail later in this manual,
to set up a typical point-to-point SAN configuration based on
FIGURE 5-1
.
1. Check the position of installed SFPs. Move them as necessary to support the
connections needed.
2. Connect expansion units, if needed.
3. Create at least two logical drives (logical drive 0 and logical drive 1) and configure
spare disks.
For half of the logical drives, keep the logical drives assigned to the primary
controller by default. For the other half of the logical drives, assign the logical drives
to the secondary controller to load-balance the I/O.
4. Create up to 32 partitions (LUNs) in each logical drive, for each server.
5. Change the Fibre Connection Option to “Point to point only.”
6. For ease of use in configuring LUNs, change the host IDs on the four channels to
be the following assignments:
Channel 0: PID 40 (assigned to the primary controller)
Channel 1: PID 41 (assigned to the primary controller)
Channel 4: SID 50 (assigned to the secondary controller)
Channel 5: SID 51 (assigned to the secondary controller)
Caution – Do not use the command, “Point to point preferred, otherwise loop.”
This command is reserved for special use and should be used only if directed by
technical support.
7. Map logical drive 0 to channels 0 and 1 of the primary controller.
Map LUN numbers 0 through 31 to the single ID on each host channel.
