Enhance VIOS "Virtual SCSI Optical/ISO images" --- to mirror VMware ESXi functionality for "Virtual SCSI Optical/ISO images"

But, I don't want to have to create/manage 100 vhost/vtopt device pairs so I have to do this DLPAR procedure 100 times:

#####################################
chhwres -r virtualio -m Server-9119-MME-SN2198F57-LR -o a -p LPAR --rsubtype scsi -s 4 -a "adapter_type=client,remote_lpar_id=1,remote_slot_num=10"
sudo rmdev -Rdl cd0
sudo rmdev -Rdl vscsi0
chhwres -r virtualio -m Server-9119-MME-SN2198F57-LR -o r -p LPAR --rsubtype scsi -s 4
#####################################

May I ask for a Request for Enhancement of VIOS to allow a many:1 so that 1 vhost/vtopt pair can be used by 100 LPARs all at the same time accessing the exact same ISO image?

VMware ESXi manages "Virtual SCSI Optical/ISO images" this way that is why I have a desire for VIOS to work this way.

    This change would necessitate changes to the vSCSI architecture, not planned in the near term.

    IBM has evaluated the priority of this enhancement proposal relative to other future product content and determined that this RFE will not be pursued for a future product release
