To present a virtual disk to all host ports on both controllers (in other words, the
promiscuous mode), select “ALL HOSTS” instead of individual hosts.
NOTE :
The promiscuous mode may not be used with persistent reservations.
The “ALL HOSTS” setting will cause SCSI2/3 Reservation commands to
fail.
3. Select the virtual disks for this presentation.
4. Optional: You may specify the mask options and enter the LUN number.
❖ Read Only: controls read-only access
❖ Home Only: presents the specified VD from the controller, port, and RP that is
currently pathed through and if the host connection is lost, access to that VD is also
lost
❖ LUN: LUN that the virtual disk will show to the host
❖ Channels: from which host port the host will see the virtual disk
