Powering off and powering on a VSAN cluster

To power off and power on a VSAN cluster use following steps:

1. Consider increasing default repair delay as mentioned at https://kb.vmware.com/s/article/2075456 This might be important if cluster will not be powered on within 60 minutes default repair delay timings
2. Check VSAN health using retest and repair unhealthy components before powering off the cluster ( https://kb.vmware.com/s/article/2144650 )
3. Power of all non vCenter and PSC VMs.
4. Note vCenter and PSC host and login into corresponding esxi host(s) using web console
5. Also SSH to vcenter and PSC ESXi host(s)
6. Put all other hosts in maintenance mode with "no action"
7. Shutdown vCenter and PSC VMs using esxi host web console
8. Put vcenter and PSC host(s) in maintenance mode using:

   esxcli system maintenanceMode set -e true -m noAction

9. Power of all ESXi hosts

For power on:

1. Power on all ESXi hosts
2. SSH to vcenter and PSC ESXi host
3. Exit maintenance mode using:

   esxcli system maintenanceMode set -e false

4. Start vcenter VM
5. Check VSAN cluster health
6. Exit other hosts from maintenance mode
7. Start necessary VMs.
