Active/Passive Cluster - Replace one node with new hardware

Hi there,

I have to replace one Node from an Active/Passive iSCSI Cluster with new hardware.
At the moment I don't use MPIO, I use a rr-bond with two NICs.


My idea:
Shutdown all Virtual Machines (I use the Storage for VMware) and stop the Failover Cluster. Then stop the Storage Replication and shutdown the Node.
After that I can change the iSCSI IP in VMware from the Virtual IP to the IP-address of the rr-bond and reconnect it.
--> I made an standalone DSS with ISCSI out of the Active/Passive Cluster


After that I will replace the server, install Open-E and configure the storage replication.
As soon as the new storage is replicated (this will take some hours) I will stop the DSS, reconfigure the Active/Passive Cluster and start everything.



After this step is done, I will change to MPIO configuration & upgrade to V7 but I think this is no big deal....



What do you think, will this work?
Any ideas or suggestions?


Thanks.
Manuel

Try to read the following KB, it should be useful for you:

Hi Al,

I have to replace the Secondary/Passive Node, not the Primary/Active - so I guess it should be more easy as in the Knowledge Article.

So it should work like this:

1) Stop the Cluster, Shutdown SN
2) Reinstall Open-E on the new Hardware, configure the same way as the ols SN (same IPs, ...)
3) Replicate all Volumes from PN to the new SN
4) Reconfigure iSCSI Failover

I think the best is to do this in the afternoon, keep everything offline - wait until the replication is done and then reestablish the iSCSI failover.



Bye Manuel

Manuel,

This is correct if you are replacing the hardware where you will need to replicate the data again and configure the replication once more so have a maintenance widow ready.
