Link Down Timeout. This setting specifies the number of seconds the software
waits for a link to come up. The default is 0 seconds.
■
Extended Error Logging. This setting provides additional error and debug

Scan Fibre Channel Devices
This option scans the FC loop and lists all the connected devices by loop ID.
Information about each device is listed, for example, vendor name, product name,
and revision. This information is useful when configuring your QLA23xx HBA and
attached devices.

Fibre Disk Utility
This option scans the FC loop and lists all the connected devices by loop ID. You
can select a hard disk and do one or more of the following:
■
Perform a low-level format
■
Verify the disk media
■
Verify the disk data
■
Select the next drive
CAUTION!
Performing a low-level format destroys all data on the hard disk.

Loopback Data Test
This test uses the Diagnostic Loopback mailbox command to send and receive data.
Before running this test, the loop in the Fibre Channel port must be up or a loopback
connector must be installed.
