Delete member with internal iSCSI connections

Question

We have three members (PS6010's) which need to be removed due to a decomm.

All volumes have been removed ready for decomm, two of the members show 0 connections but one shows "102 internal connections not shown".

If we delete this member last what are the consequences as in all the ESXi Hosts and servers with iSCSI connections will they drop or any disruption etc?

We're trying to remove the three members with minimal disruption.

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?

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.

Sorry you've confused me even more...

We have:-
Our group has 3 Pools
Pool A with 3 members (We want to decomm all members and the pool)
This pool ha no volumes, 2 members have 0 iSCSI connections, 1 member with 100+ hidden internal connections maybe the group lead

Pool B with 1 member this will remain

Pool C with 1 member this will remain

We want to remove all three members in Pool A along with Pool A.

How do we do this with no disruption??

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.
