This utility has a command line interface and a menu interface.

To start the Dynamic TGT-LUN Discovery command line interface, issue the 
following command followed by one or more command line options:

# ./ql-dynamic-tgt-lun-disc.sh <command line options>

 lists the Dynamic TGT-LUN Discovery utility command line options and 

their abbreviations.

 show a list of tasks and the commands that perform them.

--allow-lip (-al)

Issue the loop initialization processor (LIP) when required. By 
default, the LIP is not issued, even if it is required for scanning 
LUNs. If the utility does recognize that a LIP is needed, this 
option is ignored.

--current-luns (-cl)

Display current LUNs on the system

--extended-scan (-e)

Rescan the LUNs to identify attribute changes in existing LUNs. 
You can combine this option with the --max-lun, --scan, and 
--scan--refresh options.

--help (? or -h)

Print the help text.

--interactive

Opens the Dynamic TGT-LUN Discovery utility menu interface. 
Refer to 

--max-lun (-m)

Set the maximum LUNs to be scanned; the default is 256 
LUNs.

--proc (-p)

Use the proc file system to perform LUN scanning on the 2.6 
kernel. RHEL 5 is a 2.6 kernel-based Linux distribution.

--scan (-s)

Rescans all the devices connected to the QLogic adapter. If you 
omit all command line options, this is the default.

--scan --refresh
(-s-r)

Rescans all the devices connected to the QLogic adapter, and 
removes LUNs that no longer exist. Do not attempt to use this 
option on the adapter port with active I/O operations, because it 
removes the existing LUNs before rescanning.
