VMware Command-Line Interface commands

The Windows command-line interface provided for managing ESX/ESXi systems is an invaluable tool for managing ESX infrastructure at the command-line. When using ESXi without a service console the CLI becomes even more useful.

I've gathered these commands while implementing and managing ESXi 4.0 clusters, use with caution on any production system.

ESXi 4.0 RCLI:

List the NTP servers used by the host --server esx01 --list

Add a Software iSCSI NIC named vmk2
esxcli --server=esx01 swiscsi nic add -n vmk2 -d vmhba33

List the Software iSCSI NICs
esxcli --server=esx01 swiscsi nic list -d vmhba33

List the software iSCSI status on a host --server esx01 --swiscsi --list

Enable software iSCSI on an ESX host --server esx01 --swiscsi --enable

List the adapters bound to software iSCSI
esxcli --server=esx01 swiscsi nic list -d vmhba33

List the VMKernel NICs --server esx01 --list

List the software iSCSI adapters --server esx01 --adapter --list

Set the iSCSI alias for the specified adapter --server esx01 --iscsiname --alias esx01 vmhba33

Bind a VMK software iSCSI NIC for MPIO PSA
esxcli --server=esx01 swiscsi nic add -n vmk2 -d vmhba33

Rescan a storage adapter bus --server esx01 vmhba33

Add a dynamic iSCSI discovery target --server esx01 --discovery --add --ip vmhba33

Add CHAP authentication to an iSCSI discovery target --server esx01 --authentication --level chapRequired --method CHAP --auth_username esxchap --auth_password chapacc3ss80 --ip vmhba33

Find the current ScratchConfig scratch location --server esx01 -g ScratchConfig.ConfiguredScratchLocation

Set the scratch location for ESXi --server esx01 -s "/vmfs/volumes/esxds01/Scratch/esx01" ScratchConfig.ConfiguredScratchLocation

Check if CIM OEM providers are enabled (such as Dell OM) --server esx01 -g UserVars.CIMOEMProvidersEnabled

Enable CIM OEM Providers (such as Dell OM) --server esx01 -s "1" UserVars.CIMOEMProvidersEnabled

Query the patches/updates/bulletins/VIBs installed on ESXi --server esx01 -q

Set the SNMP community for the ESXi host --server esx01 -c public

Enable the SNMP agent on an ESXi host --server esx01 -E

List the iSCSI node name --server esx01 --list --iscsiname --adapter vmhba36

List the preferred nativte multipathing (NMP) path for a device
 esxcli --server esx01 nmp fixed getpreferred -d naa.6090332880cfdc44fda634b1ca2457b8

Check whether round robin path selection is used for a device
esxcli --server esx01 nmp roundrobin getconfig -d naa.6090a02833cfdc7ffd4434b1ca5457b8 

List the disk NAA/UUIDs known to a host
esxcli --server esx01 nmp device list

List the MPIO path to device mapping --server esx01 -m

List the SCSI devices known to a host --server esx01 --list   

List the available datastores on a host --server esx01 --listds

List the contents of a datastore --server esx01 --dir [datastore]

Upload a local file to a datastore through vifs --server esx01 --put c:\temp\file.txt dir/file.txt?dsName=datastoreName

List virtual switches, port groups, uplinks and MTU -l --server esx01

Browse the datastores or local host through ssl
https://esx01/folder or https://esx01/host

Find the vmnic configuration, including driver, current speed --server esx01 -l 

Set a vNIC to auto-negotiate --server esx01 --vihost esx01 -a vmnic0

List the host-based files on an ESXi client --server esx01 --dir /host  

A few other useful VMware tips:

Recreate the rui.pfx file for VirtualCenter
openssl pkcs12 -export -in rui.crt -inkey rui.key -name rui -passout pass:testpassword -out rui.pfx

Forcefully power off a suspended VM
Delete the vmss file, and then power on the VM (state is lost)

ESXi 4.0, access unsupported ssh console through the dcui
Press Alt+F1, type unsupported, then the root password

The excellent combination of low cost, supreme productivity and optimum product quality has made the west wake up to the technical strengths of the countries like India and China. These countries are making a distinct mark of their own in the field of software development by providing services like outsource software development.

China and India have been sucking our American tailpipes for the last 50 years regarding development and Quality, they will suck on it for another 50 more. CHEERS to China and India always being second banana.
