Hello. Welcome to Reliant Technology. This short video is going to explain how to create igroups within the NetApp storage system. Today we're going to be creating an igroup for fibre channel. In the NetApp OnCommand System Manager we have a LUN created called Reliant_LUN_ F. We're going to run some CLI commands to create the igroup and also map the WWN names to the LUN. Let's begin.
First we're going to start off by typing “igroup create.” We're going to use a -F switch. This actual F switch is specifying either F for fibre channel or I for iSCSI.
Since we are going to be doing fibre channel we're going to use the -F switch. We are then going to use a -T for type. In this instance, we're going to type “VMware.” Other types that you could connect to is AIX, Linux, Windows. In this example we're going to use VMware. Then we're going to name our igroup, which is Reliant, IG for initiator group, underscore F for fibre channel. Then we're going to type in the world wide name which is 0A098289A7A2. Now we're ready to create our igroup. We hit enter.
If we go back to the NetApp OnCommand System Manager and go to initiator groups we will then do a refresh. You can see that the igroup has been created. Now we're going to add an additional world wide name to this igroup. Now we're going to type igroup-f Now, this lowercase -f is not for fibre channel or iSCSI. This actually is for LUN mapping conflict checks. This will not do a LUN mapping conflict check on the cluster partner. We definitely want to do a -f here.
Then we're going to specify the igroup that we want to add this world wide name to, underscore F. In this example I'm just going to go ahead and paste it in so I don't have to type it out. Now that added the other world wide name.
Now we will come back here and do a refresh. If we go to initiators we will see that now both world wide names are in there. The last thing we will do is we will actually map this igroup to the LUN underscore F for fibre channel, that we want to give these initiators access to for this LUN.
Let's go back to the CLI. Now we will do a LUN map -f again. This is so it will not check for conflicts on the partner cluster. Then we will specify the LUN path. That includes the volume that the LUN resides in. Then we will specify the igroup that contains the initiators that we just created. Then we hit enter.
Now you see that this initiator group was mapped to this LUN. Now if we go back to this LUN and do an edit and go to initiator group you will now see that it is mapped and it automatically, since we did not specify a LUN ID to automatically to automatically assign a first available. In this case it was zero. Now we've learned how to create initiator group for fibre channel, how to assign the initiator world wide names to it and also how to map the initiator group to a LUN. Thank you so much.
