To open the menu interface, issue the following command:

# ./ql-lun-state-online.sh –interactive



If no offline LUNs are found, the menu interface does not start, the utility 
informs you that no offline LUNs were found, and the utility closes.



If offline LUNs are found, the utility main menu appears, as shown in the 
example in 

The Main menu option numbers will vary depending on the number of offline 
LUNs.

To change the state of one LUN:

1.

Type the option number of a LUN, and the press ENTER.

2.

Type the option number for OFFLINE to ONLINE/RUNNING, and then press 
ENTER.

To change the state of all LUNS from offline to online, type the option for MAKE 
ALL ONLINE, and then press ENTER.

This utility is a combination command line/menu interface that controls the time 
that the target device has to execute a command. Increasing the timeout value 
can improve performance under heavy I/O conditions, when target devices need 
more time to execute commands, resulting in the Linux SCSI mid-layer driver 
aborting fewer tasks. However, increasing the timeout value also delays the 
detection of devices that have gone offline.
