Function Description Syntax and Examples
admhost lun_activate The admhost lun_activate command scans the bus for
new devices and assigns a drive letter to all Symmetrix
and CLARiiON devices that do not already have one.
Use the -l and -d switches to scan the bus for new
devices and assign a drive letter to a device that has a
specific world wide name (WWN). This command does
not assign drive letters to any other devices.
If admhost_activate is used and no new devices are
found, and drive letters are already assigned to the
CLARiiON and Symmetrix logical units, admhost reports
an error message.
