(CLARiiON Only) Disconnected Ghost LUNs

When a Linux host is attached to both SPs in a CLARiiON storage

array, the driver will report a disconnected LUN 0 on SPB and a fail-

ure to read the capacity of the device. The Navisphere Host Agent

requires that disconnected LUN 0 be reported properly.

For both RHEL and SLES, the scsi_allow_ghost_devices parameter

must be enabled in

/etc/modules.conf.

The use of the scsi_allow_ghost_devices parameter allows the Linux

host to correctly identify the disconnected LUN 0 so that the Navi-

sphere Linux Host Agent can utilize it.

A device file name is allocated to the disconnected LUN 0 in the

/dev

filesystem, but the device cannot be mounted, partitioned, or other-

wise accessed.
