Enable SSH on the ESXi Machine and run the following

esxcfg-info | grep "Serial N"

If this doesnt work then you can use something like this in powershell however it needs Vcenter and Vsphere CLI

Get-VMHost | Select Name,
    @{N='Serial';E={(Get-EsxCli -VMHost $_).hardware.platform.get().SerialNumber}} |
Export-Csv serial.csv -NoTypeInformation -UseCulture

The below command needs to be run on Each Host , it  will remove the old one and install the new one

esxcli software vib install -d https://update.nimblestorage.com/esx6.5/ncm/index.xml

The host then needs to be rebooted to install

You can add https://update.nimblestorage.com/esx6.5/ncm/index.xml , as an update location via Update Manager in Vmware Vcenter Server and Add a Host Basline Extension , then remediate this to the hosts as well

clip_image0024[1]When provisioning a new VMware host important things to configure

1) NTP Server
2) IP of Management with DNS Name
3) Portgroup Names
4) Syslog Server
5) SNMP Trap for monitoring
6) Renaming Local Datastore to something with the server name other than datastore1
7) Nic Teaming

Another thing that is also important to setup is the pass selection policy. Depending on the SAN Manufacturer they will tell you the recommended policy e.g. https://vstorage.wordpress.com/2013/03/28/optimising-vsphere-path-selection-for-nimble-storage/

1) Fixed
2) Round Robin
3) Recently used

Most of the time it will be Round Robin

This can be changed via Command Line

esxcli storage nmp satp set -s VMW_SATP_ALUA -P VMW_PSP_RR

or through the VMWare Client

Go to Configuration Tab on Host , go to Storage , Go to Properties of Datastore and click Manage Paths

When changed make sure no VM’s are on the host as this could disrupt them
