FC HBA Change LUN State Utility

This utility is a combination command line/menu interface that changes the state (online/offline) of LUNs connected to a QLogic adapter, without rebooting the server. For example, if a SCSI command times out on a device, and fails to recover the device, the SCSI mid-layer places the device offline. Later, when the device is online, you can use the FC HBA Change LUN State utility to change the state to online.

The FC HBA Change LUN State utility performs the following tasks:

Selects a host (Converged Network Adapter port) on which to enable logical LUNs attached to it

Enables all offline LUNs with single command

Selects targets for every host (menu interface only)
