ql-set-cmd-timeout

ql-set-cmd-timeout(8)					       System Administration					     ql-set-cmd-timeout(8)

NAME

       ql-set-cmd-timeout - set the timeout on the devices connected to the QLogic FC HBA.

SYNOPSIS

       ql-set-cmd-timeout [OPTIONS]

DESCRIPTION

       QLogic Linux Set Device Timeout Utility

       This  utility allows you to set the timeout on the devices connected to the QLogic FC HBA.  This timeout value applies to the commands sent
       to the device. This can help when target devices take longer to execute a command, for example under heavy I/O. Setting	a  longer  timeout
       reduces the chance of the Linux SCSI mid-layer driver aborting the tasks after a timeout.

	      [DEFAULT]

	      Display timeout of devices connected to all HOSTs

	      [HOST]

	      Display timeout of devices connected to HOST

	      [HOST] [TARGET]

	      Display timeout of devices connected to a TARGET on HOST

	      [HOST] [TARGET] [TIMEOUT]

	      To set timeout on devices connected to a TARGET on HOST

       -h,  --help, ?
	      Prints this help message

       -i,  --interactive
	      Use this option to use the menu driven program
