Chapter 5 First-Time Configuration 5-9
Note – Resetting the controller can result in occasional host-side error messages
such as parity error and synchronous error messages. No action is required and the
condition corrects itself as soon as reinitialization of the controller is complete.
14. Save the configuration to a disk. See “Saving Configuration (NVRAM) to a Disk”
on page 5-59 .
15. Make sure that the cabling from the RAID array to the hosts is complete.
Note –
You can reset the controller after each step or at the end of the configuration
process.
Caution – Avoid using in-band and out-of-band connections at the same time to
manage the array. Otherwise, conflicts between multiple operations can cause
unexpected results.
5.4.1 Point-to-Point Configuration Guidelines
Remember the following guidelines when implementing point-to-point
configurations in your array and connecting to Fabric
switches:
■
The default mode is “Loop only.” You must change the Fibre Channel Connection
mode to “Point-to-point only” with the firmware application.
Caution –
If you keep the default loop mode and connect to a Fabric
switch, the
array automatically shifts to public loop mode. As a result, communication
between the array and the switched Fabric runs in half duplex (send or receive)
instead of providing the full duplex (send and receive) performance of point-to-
point mode.
■
Check the host IDs on all the channels to ensure that there is only one ID per
channel (on the primary controller or on the secondary controller) for point-to-
point mode. When viewing the host IDs, there should be one primary controller
ID (PID) or one secondary controller ID (SID); the alternate port ID should
display N/A. Proper point-to-point mode allows only one ID per channel.
■
If you change to “Point-to-point only” and attempt to add a second ID, the
controller does not allow you to add an ID to the same controller and channel. For
example, if you have ID 40 on CH 0 PID, and N/A on CH 0 SID, the controller
does not allow you to add another PID to CH 0.
