Hello,

I read your contribution to scsidev, regarding HSV.
You seem to have an intimate knowledge of these controlers.
Do you happen to have a clue on how to force the activation of a ghost
LUN from a Linux host ?

The rationale being : in a multipath config, when all active path are
exhausted you should be able to activate the ghosts paths rather than
let the device die.

More generally, how do you manage access to your HSV LUNs ? I personnaly
would hate to use SecurePath which locks the user to one distribution
and has not passed the "community peer-review test". Any alternative
applicable in a dual fabric, dual attached hosts & controlers (4
paths/host including 2 ghosts : 2 paths through the left fabric, 2 paths
through the right) ?
