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

More useful command-lines

This is the second edition of useful command lines, adding another 132 commands that I've found useful. Note that many of the command-line calls may require Microsoft utilities (such as dsquery, wmic, dnscmd).

Most of the commands are for the windows-based command interpreter, with a few PowerShell and ESX service console commands creeping in. They range from diagnostics, troubleshooting and simply automating recurring tasks.

Each command-line can be copied and pasted at the command prompt, if you use a batch file you'll need to reference variables with double-percent (%%).

See the original post with another 425 commands

Given an IP and mask, return the subet the IP belongs to
for /f "tokens=1-8 delims=.- " %i in ('echo') do set /a Octet1="%i & %m" >nul & set /a Octet2="%j & %n" >nul & set /a Octet3="%k & %o" >nul & set /a Octet4="%l & %p" >nul & Echo %i.%j.%k.%l,!Octet1!.!Octet2!.!Octet3!.!Octet4!,%m.%n.%o.%p
