Hi,
my company is developing some sort of API for iSCSI managing, and at
this time we are trying to figure out how to create and delete targets
using ctladm and not usingb the configuration file.
And the relationship between LUNs and ports are unclear to us if we
don't use the configuration file. As abount the creation of LUN
everyting is clear:
ctladm create -b block -o file=/dev/zvol/dataflash/kvm/emz -o
ctld_name=iqn.2016-04.net.playkey.iscsi:emz666,lun,0 -o
scsiname=iqn.2016-04.net.playkey.iscsi:emz666,lun,0 -d EMZ666 -S EMZ666
But what next ? How do I create the port ? Because without port there's
no way the iSCSI initiator would see the target. And there's no port,
create created only the LUN:
