Resetting a Host Channel on an FC Storage
System
For a Fibre Channel system using loop topology, you might need to reset a host port
(channel) to fix a host connection or configuration problem. As an Advanced
Manage user, you can use this command to remotely issue a loop initialization
primitive (LIP) on specified controller ports.
To reset a host port:
1. Select Manage > Utilities > Host Utilities > Reset Host Channel.
2. Set the channel and controller options.
3. Click Reset Host Channel.
Changing PHY Fault Isolation Settings
PHY lanes are the physical signal paths used for communication between the SAS
expander in each controller module and the drive modules in a system. The
Expander Controller in each controller module automatically monitors PHY error
(fault) rates and isolates (disables) PHYs that experience too many errors.
The Expander Isolation page is similar to the Expander Status page, but enables you
to reset expander error counters, manually disable or enable individual PHYs, and
disable or enable PHY fault isolation.
Use of the Expander Status page is described in “Checking PHY Status” on page 47
and in the
reference guide .
