Controller LUN Automap. Select Enabled (the default setting) to
obtain user-level control for mapping the storage array controller (SCSI
Device Type 0x0C). When enabled, the controller LUN is automatically
mapped to all hosts. Or, select Disabled to instead manually map the
controller LUN to hosts.
Time to Target Device Offline. This setting defines the time for which
the iSCSI target device remains presented into the Fibre Channel SAN
after the iSCSI target device has disappeared or logged out on the
iSCSI side. Use this setting to handle conditions where the iSCSI
target device logs out temporarily and then logs back in.
Specify a value of 0 to have the presentation immediately
removed.
Specify a value of 30 to have the presentation of the Fibre
Channel device remain intact for 30 seconds after the iSCSI
target device has logged out.
QLogic recommends a time to target device offline of 30 seconds to
ensure that if the iSCSI target device temporarily logs out (disappears)
and then logs back in within 30 seconds, the I/Os can resume without
causing any disruption in the Fibre Channel SAN.

NOTE:
Use the Time to Target Device Offline parameter in a
configuration where iSCSI target devices are mapped into the
Fibre Channel SAN using the iSR6200. This parameter applies
only to iSCSI target devices.
