Power and maintenance operations in ESXi 5.1 with esxcli

September 18, 2012 4 comments

ESXi 5.1 comes with many improvements and one of them is new namespaces and commands in esxcli.

Those new commands enable a system administrator to perform a shutdown, a reboot or a maintenance operation in a host.

Under the system namespace the new commands are the equivalents of the classic vicfg/esxcfg-hostops which until now was the only way to perform such kind of operations with vCLI and are also accesible locally on ESXi Shell.


Maintenance mode operations

Getting the basic usage of the command is as simple as always. You can perform two operations.

  • Get the state of the host
  • Put the the host in or out of Maintenance Mode
~ # esxcli system maintenanceMode 
Usage: esxcli system maintenanceMode {cmd} [cmd options]
Available Commands: 
  get                   Get the maintenance mode state of the system. 
  set                   Enable or disable the maintenance mode of the system. 
~ #
  • Get the state of the host
~ # esxcli system maintenanceMode get 
~ #
  • Put the host in Maintenance Mode
~ # esxcli system maintenanceMode set -e true -t 0 
~ # 
~ # esxcli system maintenanceMode get 
~ #

Power operations

With the shutdown command the host can be either rebooted or shutdown. If the ESXi server is not in Maintenance Mode mode the operation will not be allowed.

~ # esxcli system shutdown 
Usage: esxcli system shutdown {cmd} [cmd options]
Available Commands: 
  poweroff              Power off the system. The host must be in maintenance mode. 
  reboot                Reboot the system. The host must be in maintenance mode. 
~ #

For both task the delay and reason parameter must be provided.

~ # esxcli system shutdown poweroff 
Error: Missing required parameter -r|--reason
Usage: esxcli system shutdown poweroff [cmd options]
  poweroff              Power off the system. The host must be in maintenance mode.
Cmd options: 
  -d|--delay=<long>     Delay interval in seconds 
  -r|--reason=<str>     Reason for performing the operation (required) 
~ #
  • Power off the host
~ # esxcli system shutdown poweroff --delay=10 --reason=”Hardware maintenance”
  • Reboot the host
~ # esxcli system shutdown reboot -d 10 –r “Patches applied”


Change ESXi 5 iSCSI iqn with esxcli

After my previous post about getting the iqn of an ESXi using esxcli Andy Banta (@andybanta) commented on Twitter that you can also change the iqn of the host with esxcli.

As he said it would be tremendously useful if you need to physically replace the server and don’t want to modify all your storage infrastructure, it’s easier to just modify the iqn of the new server and set it to the old name.

The task is as easier as the one described in last post. Using esxcli command with the iscsi namespace you can change the name and the alias of the adapter.

As a precaution first retrieve the current iqn to check that it’s the correct server.

Screenshot from 2012-08-02 21_20_08

To change the name you have to provide the adapter and the new name.

Hope you find this useful, any comments and suggestions are welcome as always.


How to get iSCSI iqn using esxcli in ESXi 5

Back in 2010 I wrote a post about how to get the iSCSI iqn of an ESXi 4.x server using vSphere CLI from the vMA or any other system with the vCLI installed on it.

The method described in that article is still valid for ESXi 5.0 since the old vicfg and esxcfg commands are still available, however with 5.0 version you can get a similar result using the new esxcli namespaces, following is how to do it.

First task is to get a list of the iSCSI HBAs in order to know the name of the software iSCSI initiator.


Next we get the info of the adapter.


Look at the Name field to get the iqn and we are done.


New esxcli namespaces included on the HP ESXi image

January 9, 2012 5 comments

If your VMware infrastructure runs on top of HP servers, rack or blade, you should be familiar with the HP customized ESXi images. Hewlett Packard has been releasing theses images since ESXi 4.0 and with the release of vSphere 5 a new image has also been released.

This images comes bundled with utilities and drivers not included in the standard VMware image that allows ESXi to run flawlessly on HP hardware.

You can retrieve the packages specifically provided by using the esxcli command.

~ # esxcli software vib list |grep Hewlett-Packard
char-hpcru           Hewlett-Packard     PartnerSupported  2011-04-16 
char-hpilo            500.     Hewlett-Packard     PartnerSupported  2011-04-16 
hp-esx-license        1.0-03                              Hewlett-Packard     PartnerSupported  2011-04-16 
hp-smx-provider       500.              Hewlett-Packard     VMwareAccepted    2011-04-16 
hpbootcfg             01-00.10                            Hewlett-Packard     PartnerSupported  2011-04-16 
hponcfg               03-02.04                            Hewlett-Packard     PartnerSupported  2011-04-16 
~ #

To get detailed information of any of those packages use the following command.

~ # esxcli software vib get -n hp-smx-provider
   Name: hp-smx-provider
   Version: 500.
   Type: bootbank
   Vendor: Hewlett-Packard
   Acceptance Level: VMwareAccepted

   Live Install Allowed: True
   Live Remove Allowed: False
   Stateless Ready: True
   Overlay: False
   Payloads: hp-smx-provider
~ #

Aside from the drivers and monitorization agents, the HP image also adds two additional namespaces to esxcli.

  • hp
  • hpbootcfg

The first one, hp, manage the HP NMI driver.

~ # esxcli hp
Usage: esxcli hp {cmd} [cmd options]
Available Namespaces:
  hpnmi                 The default set of operations for the hpnmi command
~ # esxcli hp hpnmi
Usage: esxcli hp hpnmi {cmd} [cmd options]
Available Commands:
  load                  Verifies HP server and Loads hpnmi module on supported servers
~ #

The hpbootcfg namespace is used to configure the device boot order of the server. This can be permanent or a one time boot change.

~ # esxcli hpbootcfg
Usage: esxcli hpbootcfg {cmd} [cmd options]
Available Commands:
 execute execute hpbootcfg command with options parameter
 help show hpbootcfg help
 show show current hpbootcfg settings
~ #
~ # esxcli hpbootcfg show
00 00: Normal Device first, normal boot process

~ #
~ # esxcli hpbootcfg execute --help
Usage: esxcli hpbootcfg execute [cmd options]
 execute execute hpbootcfg command with options parameter

Change ESXi 5.0 hostname with esxcli

November 15, 2011 3 comments

Yes another post about esxcli, what can I say I’m studying very hard for my VCP5 and from time to time this kind of unknown information, at least for me, arise and I believe it can be useful for some of you.

Again we are going to make use of the system namespace.

~ # esxcli system hostname
Usage: esxcli system hostname {cmd} [cmd options]
Available Commands:
  get                   Get the host, domain or fully qualified name of the ESX host.
  set                   This command allows the user to set the hostname, domain name or fully qualified domain name of the ESX host.
~ #

First task of course is to get current hostname.

~ # esxcli system hostname get
   Domain Name: vjlab.local
   Fully Qualified Domain Name: esxi5.vjlab.local
   Host Name: esxi5
~ #

Next change the hostname, but you should check before what options are at your disposal by getting the command help.

~ # esxcli system hostname set --help
Usage: esxcli system hostname set [cmd options]
  set                   This command allows the user to set the hostname, domain name or fully qualified domain name of the ESX host.
Cmd options:
  -d|--domain=<str>     The domain name to set for the ESX host. This option is mutually exclusive with the --fqdn option.
  -f|--fqdn=<str>       Set the fully qualified domain name of the ESX host.
  -H|--host=<str>       The host name to set for the ESX host. This name should not contain the DNS domain name of the host and can only contain letters, numbers and '-'. NOTE this is not
                        the fully qualified name, that can be set with the --fqdn option. This option is mutually exclusive with the --fqdn option.
~ #

Interesting, you can change the short hostname, the domain or the fully qualified domain name. Take into account that –fqdn option is mutually exclusive with the others.

We are going to try all of them.


~ # esxcli system hostname set --domain=jreypo.local
~ #
~ # esxcli system hostname get
   Domain Name: jreypo.local
   Fully Qualified Domain Name: esxi5.jreypo.local
   Host Name: esxi5
~ #

Short hostname:

~ # esxcli system hostname set --host=esxi5-2
~ #
~ # esxcli system hostname get
   Domain Name: jreypo.local
   Fully Qualified Domain Name: esxi5-2.jreypo.local
   Host Name: esxi5-2
~ #

Fully qualified domain name:

~ # esxcli system hostname set --fqdn=esxi5.vjlab.local
~ #
~ # esxcli system hostname get
   Domain Name: vjlab.local
   Fully Qualified Domain Name: esxi5.vjlab.local
   Host Name: esxi5

Getting network card driver version in ESXi 5.0

November 15, 2011 Leave a comment

This a quick follow-up post to the How to check the driver version of a network interface in ESX(i) one. That post covered ESX(i) 4.x so I decided to write a small update for ESXi 5.0.

First I have to say that the two methods described in my first post still work in ESXi 5.0 Shell.

~ # vmware -l
VMware ESXi 5.0.0 GA
~ #
~ # vmkload_mod -s e1000 | grep Version
Version: Version, Build: 456551, Interface: 9.2 Built on: Jul 29 2011
~ #
~ # ethtool -i vmnic0
driver: e1000
firmware-version: N/A
bus-info: 0000:02:00.0
~ #

Thanks to the new changes made by VMware in ESXi 5.0 we can now use esxcli to get the same result.

~ # esxcli system module get -m e1000
   Module: e1000
   Module File: /usr/lib/vmware/vmkmod/e1000
   License: GPL

   Version: Version, Build: 456551, Interface: 9.2 Built on: Jul 29 2011
~ #

There is a big advantage on using esxcli over the other methods. In ESX(i) 4.x and ESXi 5.0 with the old procedure you had to be logged into the host but with esxcli it can be performed remotely using vSphere CLI.

vi-admin@vma:~[esxi5.vjlab.local]> esxcli system module get -m e1000
   Module: e1000
   Module File: /usr/lib/vmware/vmkmod/e1000

   Version: Version, Build: 456551, Interface: 9.2 Built on: Jul 29 2011

But there is more, thanks to Get-EsxCli cmdleet the same operation can be done using PowerCLI, here it is how.

First we need to setup the Esxcli instance.


And now we issue the command using the name of the module as the argument, please pay attention to the syntax.


As you should have imagined this procedure can be used to get info about any VMkernel module in the host, not just the network interface one,.


Change ESXi 5.0 Shell keyboard layout with esxcli

November 14, 2011 Leave a comment

If you have to login into the ESXi 5.0 Shell and the keyboard layout is not the one you are used to this post will show how to quickly change it.

As always in vSphere 5 we are going to use esxcli command to get the job done.

Get current keyboard layout:


As you can see we are using system settings keyboard layout namespaces and the command get. The other available commands are list and set.

List available layouts:


Change keyboard layout:

The syntax for the command can be retrieved by appending –help to the command.


Now change the layout to “US Default”.


Keep in mind that this will change the layout permanently, as it can be seen in the command help the layout can also be changed only for the current boot and it will be reset to its original value during next reboot of the host.


With the —no-persist option the host will report its original layout.


List packages installed in ESXi 4.1 and 5.0

October 27, 2011 2 comments

Today a co-worker has asked me how to list the packages installed in an ESXi 4.1 Update 1 server, in the ESX COS we had the RedHat rpm command but in ESXi there is no rpm and of course there is no COS.

His intention was to look for the version of the qla2xxx driver and my first thought was to use vmkload_mod, the problem is that with this command you can get the version of a driver already loaded by the VMkernel and we wanted to look for the version of a driver installed but no loaded.

I tried esxupdate with no luck.

~ # esxupdate query
----Bulletin ID----- -----Installed----- --------------Summary---------------
ESXi410-201101223-UG 2011-01-13T05:09:39 3w-9xxx: scsi driver for VMware ESXi
ESXi410-201101224-UG 2011-01-13T05:09:39 vxge: net driver for VMware ESXi    
~ #

Then I suddenly thought that the ESXi Tech Support Mode is based on Busybox. If you have ever use a Busybox environment, like a QNAP NAS, you will probably remember that the way to install new software over the network is with ipkg command and to list the software packages already installed the syntax is ipkg list_installed.

There you are :-) There is one gotcha to get the version, it starts just after the 400.

Next task of course was to do the same in ESXi 5.0.

~ # ipkg list_installed
-sh: ipkg: not found
~ #

Ouch! Ipkg has been removed from ESXi 5.0. The key to get the same list is esxcli.

A final thought for all of you starting with vSphere 5, esxcli is the key in ESXi 5.0 shell.


DNS configuration with esxcli

October 17, 2011 3 comments

With release of ESXi 5.0 the esxcli command has been also vastly improved. One of this new capabilities is the possibility to manage the DNS configuration of the server.

The basic syntax for dns is:

~# esxcli network ip dns

This gives you two namespaces to work with:

  • search
  • server


With the first one you can manage the suffixes for DNS search and the second is for the DNS server to be used by the ESXi.

  • Server operations
    List the servers configured:


Add a new server:


Remove a configured server:


  • Domain search operations

List configured domain suffixes:


Add a new domain:


Remove a configured domain:



List ARP table entries of an ESXi

September 13, 2011 2 comments

Like we found before for netstat there is no arp command available from within ESXi Tech Support Mode, so how can you list the ARP table entries if you need to? Or how can you do it remotely either with vCLI or PowerCLI?

In this quick post I’ll show you the different ways to list the ARP table entries of an ESXi server, as always both for ESXi4 and ESXi5.

Tech Support Mode

From ESXi Tech Support Mode we need to relay in esxcli.




Again we need esxcli in order to get the ARP table.


In this case we are going to use esxcli but trough the Get-EsxCli cmdlet. First we retrieve the esxcli instance and then we get the ARP table list.
