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)
