Shut Down and Power Off HyperFlex Storage Cluster

1. First, backup the HX/UCS configuration through the UCS Manager (Click on Creating a Backup Operation).
a. https://www.cisco.com/c/en/us/td/docs/hyperconverged_systems/HyperFlex_HX_DataPlatformSoftware/AdminGuide/3_0/b_HyperFlexSystems_AdministrationGuide_3_0/b_HyperFlexSystems_AdministrationGuide_3_0_chapter_0100.pdf
2. Next, shut down all the VMs in the cluster or migrate the VMs to a new cluster.
3. Log into one of the storage cluster VMs (you can click on one of the storage cluster VMs to get an IP to SSH into).
4. Perform the following command to shut down the cluster:
a. # stcli cluster shutdown
5. Next, run the following command to confirm cluster is offline:
a. # stcli cluster info
b. Confirm the “healthstate” is “unknown” to verify it is offline.
6. Next, power off the storage controller VMs in vCenter by doing the following:
a. Find the storage VMs and right click
b. Select Power>Shutdown Guest OS (Cisco shows Power Off also shuts down gracefully, although I have not called Cisco to confirm this. As all VMs, I use “Shutdown Guest OS” instead for now.
7. Finally, you can now shutdown the ESXi hosts in the cluster in vCenter by doing the following:
a. Locate the ESXi host and right click.
b. Select Power>Shutdown and put in the reason why you are shutting the system down.
8. The cluster is now shut down. If you need to shut down the UCS FIs, then Cisco recommends you can just pull the plug on them since there is no other tasks to shut these down.
