Delete member with internal iSCSI connections

Thanks for the reply.

I can move the members one by one to the new pool starting with the two having no iSCSI connections but ultimately the last one with all the current internal connections will then be the last member in the pool as we're also removing the pool so it won't have the ability to move any potential data/connections within the pool to a remaining member in that pool.

It's interestingly the only member that lists these internal iSCSI connections, could it be some sort of 'master' member?

Yes it may be group lead.

I want to remove all members and the pool they reside in as a decomm.

So can I 'delete member' all three members in turn and when I remove the last member the pool will delete as well? It'll pass the group lead to another member in another pool without disruption?

Hello, 

 That member could be the Group Lead.  Which handles logins and owns the event logs.  

  I'm not 100% following what you are trying to do in your first paragraph. 

  You have members that you want to remove from the group.  When you get down to the last member in the pool, you won't be able to delete that member or pool.   Delete member only works when you have more than one member in a group.   When you get down to the last member, you have to go to the Group CLI and enter "reset".    Then it will prompt you to confirm it with "DeleteAllMyDataNow"   (case sensitive) 

 Or did you mean when you get down to the last member you want to delete.  The one with internal connections can be moved and deleted as well.  If it is the group lead, that function will move to the final member automatically.

Hello, 

  Sorry if I confused you.  Since you have at least one more member in the GROUP (vs. Pool) you can use the Delete Member.  If you also deleted the member in Pool B, you would be left with just one member in that Group.  That's when you have to use the 'reset' option at the CLI.   Since there are no more members at all in the group.  Regardless of the number of pools.  

 So for pool A.  If there is no data there, they you can use the delete member to remove them one at a time. This will be w/o disruption to the other pools.   When the last member is gone, you can delete that pool.

Hello, 

 If you have FOUR arrays in that group, and move three of them into a temp pool, then yes you can delete all of those members and delete that temp pool.   You just can't use "Delete member" to get ride of the last member in a Group.  That's when you use reset at the CLI.   Also NEVER user 'reset' 'when there are more than one member in a group.  Always use "delete member".

Thanks it makes sense.

I'm assuming the group lead role will move to another member? I can't see a way to move it.
I was just concerned over these unknown internal iSCSI connections, thinking perhaps somehow hosts/servers where connected to it and then it was passing the connection through to the other members and taking that member down would cause a disruption.

Thanks :emotion-1:

You are most welcome.  I'm glad I could help out.

When only having the GUI one way to find out which is your Group Lead(GL) is to click on the Monitoring tab in the bottem left. Under normal conditions 99.9% of all msg are comming from a single member.... thats your current GL.

I suggest that you delete this member at the last one of your 3 because that the GL role has only to move once.
