Just wondering if tgtd can take a command from tdtadm to start a new instance of tgtd with control port and iscsi portal. The usage scenario I have is this: - tgtd starts as it is today from init scripts without any control port or iscsi portal addresses - User defines targets in targets.conf file with target-address - tgt-admin invokes tgtadm command to create tgtd with specific control ports - tgt-admin sends (thru tgtadm) target create requests to control ports if the target has target-address - tgt-admin sends (thru tgtadm) target create request to the tgtadm that doesn't have any control port associated - When tgtadm needs the listing of targets, tgtadm provides it with all the targets it controls and all the control ports defined. And tgt-admin uses all the control ports to get the targets connected to each of the control ports This needs some additional changes to tgtadm. Or is it already implemented that way ? If this model won't work, how do I use the control port model with tgtd needing to start at a time where all the control ports and ip addresses are not known (boot time) and how tgt-admin will get target information for all the control ports ? regards, chandra On Thu, 2010-04-01 at 09:54 -0700, Chandra Seetharaman wrote: > 1.
