I don't want to spend your too much time, but I feel that 7mtt Host has the connection to "7-Mode system FQDN" only, no connection to cDOT.   Thank you so much, you helped me out! ... View more

Thanks a lot, Hadrian!   I am not sure if you saw this message, since we are writing at the same time.   My last question, I hope. If we give the target SVM a new IP, then the clients will have to change the DNS name in NFS mounting cases, and to reference the new location, correct?   Is this required to have this IP "7-Mode system FQDN" have connections to both 7-mode filer and cDOT? ...

Very good! Should this IP "7-Mode system FQDN" have connections to both 7-mode filer and cDOT?   I used “transition lif show –s 7mode_standalone” and got “No IP addresses to display” back, which indicating this session did not specify any DATA LIF to be provisioned.   However, meanwhile when I run “net int show -vserver cdot-7mode” on cDOT, the result indicates two LIF interfaces are already up. What am I missing here? How should I explain it? Does that mean these two LIF’s were already created manually, not by 7mtt, and that’s why the 7mtt command could not recognize them? The vserver “cdot-7mode” is the target SVM.   My last question, I hope. If we give the target SVM a new IP, then the clients will have to change the DNS name in NFS mounting cases, and to reference the new location, correct? ... View more

  Great messages, Hadrian, Thank you!   Now to help me fully understand the process, here is the question I need to unerstand first: What is "7-Mode system FQDN" created for, if "Data-copy IP address" is used for Snapmirror between 7-mode filer and cDOT?     ... View more

Sorry, I might be missing something here.   In "Data Copy phase", we have started baseline transfer, what IP we are using to do the initialization? and what is the difference between this IP and later the IP for SVM? how do I find that out and verify what these two IP's are, respectively? please show me CLI's if you could.   Thanks for patience. ...

Hello Hadrian,   Your messages are very helpful. I have a few follow-ups.   The section "Configuring the data LIFs on the SVM" I excerpted from "Precutover phase" in Doc "Data and Configuration Transition Guide". Understood that I could use the existing 7-mode filer IP for the target SVM, however, in most cases, we probably use a new IP for the target SVM, since we usually don't transition all volumes on 7-mode at once.   Here is what I am still confusing about. During "Data copy phase", we have initiated baseline transfer and data should be already transfered to target SVM, which means that we have already given the IP to SVM at this phase. Correct? If correct, then why do we still need to give an IP to SVM in Precutover phase?     ... View more

Anybody please share your idea?   Configuring the data LIFs on the SVM: Existing 7-Mode IP addresses are created on the SVM in the administrative down state. New IP addresses are created on the SVM in the administrative up state. I am not sure I understand above two statements. Does that mean that I am going to use the same IP for 7-mode filer and configure it for SVM  on cDOT? ... View more

As I understand, one way is to use a new IP for SVM, and requires to update DNS address   To prevent the situation where users are using IP address not DNS name, one could also use the same IP for SVM on 7-mode right before cutover, and without changing DNS name.   Which method should be more commonly used? ...

I am sorry, I did not make myself clear. Let me try again:   1. I am creating volume SnapMirror, not using SnapManager. 2. I am doing so from Source cluster GUI. When I clieck on Mirror, it bring me to next page, requires me to enter the new volume name on DEST cluster, and all other SM configurations. Before that, I need to enter authentication information to connect the DR cluster. I am getting "Cluster unreachable", after I enter them.           ... View more
