I was looking for help on how to achieve the following: properly retire 5 ESXi 6 hosts from a 10 node ESXi 6 cluster.
I have a 10 node production ESXi 6 cluster. I need to retire (decommission) 5 hosts from it. The cluster has shared storage - EMC Unity - 30 LUNs. The storage is connected via FC. All hosts are boot from SAN. I need to make sure I can safely remove 5 hosts, in particular, disconnect them from the storage so that the other hosts do not lose connectivity to any of the LUNs. I looked around, thought it over, and came up with the following plan:
Can you please let me know if this make any sense? If there is a better way to address this please share.
Appreciate your input.
Yeah looks good. Don't overcomplicate decommission.
REmoving hosts is easy adding them is tricky because you can break something, but removing them other than make sure old HBA and zones are removed from defunct servers is simple.
