Quantum Scalar i6000 User's Guide
On the Configuration tab, settings are unavailable if the current
state of the tab is set to Disabled.
Be aware that there might be incompatibilities with channel zoning
configuration on the I/O blade if you enable host port failover.
7 Accept the recovery setting default values unless an authorized
representative advises you otherwise.
8 Before you set recovery settings, understand the following elements
in the Recovery Setting area:
• Error count recovery mode sets the recovery scenario for all
ports when port failure is caused by excessive errors on the port.
The only setting option is Require Intervention.
• Link down error recovery mode sets the recovery scenario for
all ports when port failure is caused by the port going offline for
more time than the threshold specified in the Link down delay
time text box. The only setting option is Require Intervention.
• Link down delay time sets the timeout threshold before link
down status applies. The default value is zero (0) seconds. There
is no maximum value. Require Intervention means that a user
must manually use the Physical Ports tab to bring a failed port
that has recovered back online.
9 Configure the Primary Port. Only ports that are in target mode and
point-to-point connection can participate in host port failover. The
primary port becomes active by default and the alternate port will
go on passive standby until a failover occurs. Use the Select
Primary drop-down list to select from the target ports that are
online and available. You must select a primary port. Current Active
indicates the currently active port.
10 Click Set. If your configuration has errors, a warning message
appears.
Enabling a Target Port
Use the Physical Ports tab to manually enable an online target port that
was disabled because of a previous connection error. If the Intervention
column displays "true," you must manually bring the recovered port
back online using Enable. If the port state is "disabled," the port's
connection is repaired and it is ready to be re-enabled. If the
Configuration tab itself is disabled, the table on the Physical Ports tab
will be empty.
