Set the HBA polling and host polling intervals to retrieve host status alarms
(see
“Specifying the Polling Intervals to Retrieve Host Status Alarms” on
page 5-16
).
Specify whether host status alarms and target status alarms refresh the
configuration (see
“Specifying Whether the Configuration Refreshes When
Host and Target Status Alarms Occur” on page 5-19
).
Specify whether a message appears when a host configuration change is
detected (see
“Specifying Whether the Host Refresh Prompt Appears” on
page 5-20
).
To refresh the configuration immediately:
Choose one of the following options:
On the toolbar, click
Refresh

On the
View
menu, click
Refresh

Specifying the Polling Intervals to Retrieve Host Status Alarms
Polling intervals determine how frequently SANsurfer iSCSI HBA Manager
monitors the connected HBAs (and their targets), and updates the iSCSI HBA
Manager user interface configuration based on their state. There are two types of
polling:
HBA Polling.
and
Host Polling.
HBA Polling.
HBA polling occurs at an interval that you specify. During HBA
polling, the agent checks for changes to the HBA settings and targets. When the
agent detects a change, a host status alarm is sent to all SANsurfer iSCSI HBA
Manager interfaces currently connected with the agent.
If you set the preferences to update behavior (see
“Specifying Whether the
Configuration Refreshes When Host and Target Status Alarms Occur” on
page 5-19
, then the SANsurfer iSCSI HBA Manager user interface retrieves the
latest information from the agent.
Because alarms may not be detected by the interfaces,
Host Polling.
is also
available to ensure that the user interfaces receive the configuration changes.
Host Polling.
Host polling permits host status alarms, not received by the
SANsurfer iSCSI HBA Manager user interface, to be detected. Host polling occurs
at an interval that you specify and can be disabled.
During host polling, the interface asks the agent if anything has changed since the
last time it received an update. If not, the interface waits until the next poll or
alarm.
