To access the shell mode, type bcu shell.
To exit out of shell mode, type exit.
Use the BCU adapter command to list and query available adapters seen by the driver.
The bcu adapter --list command lists all adapters on the system with a brief summary of
information such as model number, serial number, and adapter number. Enter the following
command:
adapter --list
where:
list
Lists all adapters in the system. For each adapter in the system, a brief
information line displays containing the adapter type, model number, serial
number, and hardware path.
The adapter --query command displays adapter information, such as the current version of the
adapter, adapter type, adapter (chip revision) and driver (fw version), maximum port speed, model
information, serial number, number of ports, PCIe information, pwwn, nwwn, hardware path, flash

Data collection using Fabric OS commands (Brocade switches only)
Use the following Fabric OS commands on attached Brocade switches to gather information and
help isolate connectivity and other problems between the adapter, switch, and storage ports. For
details on using these commands, refer to the
Fabric OS Command Reference Manual
.
•
authUtil
Use this command to display and set local switch authentication parameters.
•
cfgShow
Use this command to display zone configuration information for the switch. You can use
command output to verify target ports (by port WWN) and LUNs that are intended to be
accessible from the adapter.
•
fcpProbeShow
Use this command to display the Fibre Channel Protocol daemon (FCPd) device probing
information for the devices attached to a specified F_Port or FL_Port. This information includes
the number of successful logins and SCSI INQUIRY commands sent over this port and a list of
the attached devices.
•
nsShow
Use this command to display local NS information about all devices connected to a specific
switch. This includes information such as the device PID, device type, and the port and node
WWN.
