Remove Storage Node from a MG

Exploitation67 — Fri, 02 Aug 2013 11:46:06 GMT

Hello,

Lefthand OS : 10.5 (MG version 9.5)

I want to remove a storage node from a MG which contains 2 clusters and a FOM, one cluster is composed of 6 nodes and a another is composed of 2 nodes ; both are in multi-site configuration.

I have remove successfully 1 storage node (the manager was stopped) from this MG but when I want to remove the second node I have a warning which tell me to stop the manager first with a lot of warnings.

If I try to reboot the node I have a warning with the MG could go offline...and it tell me to start a regular, virtual or failover manager.

The FOM is already started, in one cluster (composed of 6 nodes multi-site) I have 2 managers started and in another cluster (composed of 2 nodes multi-site) I have one manager started, total I have 4 regular manager and 1 Fom started.

Can I stop the manager from the node which I want to remove from the MG and after that remove it from the MG without any problem?

Attached are the warning messages.

Thanks in advance.

Hello,

Without actually looking at the CMC I cant tell how many mangers you have running.

If you have muliti-site and you have 6 nodes, the nodes to remain equal on each site. That is part of the requirement of setting muliti-site.

I've got the response from the HP support.

In CMC 10.X you can't start a regular manager from the interface if you've already have 5 managers.

I stopped the manager on the node that I want to remove then I have the choice to start a regular manager (and I start it) on an other node and all works fine.
