SCSI test
Use the fcdiag --scsitest BCU command to test the SCSI link between the adapter and remote port.
fcdiag –-scsitest <port_id> <rpwwn> [-l lpwwn]
where:
port_id
ID of the port for which you want to test the SCSI link. This could be the
PWWN, port hardware path, or user-specified port name. This could also be
the adapter-index/port-index. For example, to specify adapter 1, port 1 you
would use 1/1 as the port identification.
rpwwn
Remote PWWN connected to the adapter by the SCSI link.
lpwwn
Logical PWWN. 0 indicates the base port; otherwise, the port is a virtual port.
Test Logs
While running a diagnostic test in HCM, a log of the test results displays at the bottom of the
Diagnostic dialog box. Display details of the test log by double-clicking a row in the log.
Collecting BIOS data
Collect information on the currently configured BIOS and boot over SAN configuration using the
BCU and HCM.
Displaying BIOS data through BCU
Use the bios --query BCU command to display such information as the boot over SAN enabled or
disabled state, port speed, boot LUNs obtained from flash, and boot LUN 0 identification and target
WWN. “Preboot” means that parameters were configured using a blade system management
application. Preboot configuration data can include port speed, BIOS (boot over SAN) state, and
configured boot LUN identification.
bios --query <port_id>
where:
port_id
The ID of the port for which you want to display the port log. This could be the
PWWN, port hardware path, or user-specified port name. This could also be
the adapter-index/port-index. For example, to specify adapter 1, port 1 you
would use 1/1 as the port identification.
Display BIOS data through HCM
Display current BIOS information through the HCM Boot over SAN dialog box. Information includes
BIOS (boot over SAN) enabled or disabled state, port speed, boot option, preboot BIOS enable and
port speed, and details on current boot LUNs. To access this dialog box, use the following steps.
1. Select a host, an adapter, or an adapter’s physical port from the HCM device tree.
2. Select Configure > Basic Port Configuration.
