Restoring In-Order Delivery Of Frames; Using Dynamic Load-Sharing - HP StorageWorks MSA 2/8 - SAN Switch User Manual

Basic Switch Management

Restoring In-order Delivery of Frames

To restore the default In-order delivery setting (which allows frames to be
delivered out-of-order during topology changes for faster delivery):
1. Log into the switch as the admin user.
2. Enter the iodreset command at the command line.
Example:
switch:admin> iodreset
done.
switch:admin>

Using Dynamic Load-Sharing

Optimal load sharing is rarely achieved with DLS disabled. If DLS is turned on
(using dlsset), routing changes can affect working ports. For example, if an
Fx_Port goes down, another Fx_Port may be rerouted from one E_Port to a
different E_Port. The switch minimizes the number of routing changes, but some
are necessary in order to achieve optimal load sharing.
If DLS is turned off (using dlsreset), load sharing is performed only at boot
time or when an Fx_Port comes up.
1. Log in to the switch as admin.
2. Enter the dlsshow command to view the current DLS setting.
3. Enter the dlsSet command to enable Dynamic Load Sharing when a
4. Enter the dlsReset command to disable Dynamic Load Sharing.
