esxcli Part2 - Automating esxcli using vMA

06.17.2010 by William Lam // 3 Comments

In the previous article, esxcli Part1, we discussed what esxcli is and what it can be used for. In this article, we will show you how you can automate and perform a common esxcli operation against a set of ESX and/or ESXi hosts using vMA. As mentioned in the previous article, esxcli needs to be executed against a specific host, it is not vCenter aware and cannot connect to vCenter to perform an operation against a host.

One of the pre-requisites before starting is that all ESX and ESXi hosts need to be managed by vMA and accessible using vi-fastpass authentication. Please refer to the vMA documentation on configuring this on vMA.

Download:esxcli-automation.pl

The following script is based off of useVIFastpassOnvMAToRunPerlScriptWithoutClearTextPassword.pl. The modified script utilizes the vi-fastpass library to properly access a set of target(s) and performs the specified esxcli operation without having to provide credentials to each and every host.

The following example will demonstrate iSCSI multipath configuration on two hosts using the method described by Duncan Epping in this article.

1) Create a file containing the list host to perform the operations against:

[[email protected] ]$ cat hosts
esxi4-1.primp-industries.com
esxi4-3.primp-industries.com

2. Run the script with the specific esxcli parameters as you would normally by passing it into the --cmd_option argument (double quote the arguments):

Binding iSCSI interface to vmk0

[[email protected] ]$ ./esxcli-automation.pl --hostlist hosts --cmd_option "swiscsi nic add -n vmk0 -d vmhba33"
Executing script on "esxi4-1.primp-industries.com" ...
Executing script on "esxi4-3.primp-industries.com" ...
Binding iSCSI interface to vmk1

[[email protected] ]$ ./esxcli-automation.pl --hostlist hosts --cmd_option "swiscsi nic add -n vmk1 -d vmhba33"
Executing script on "esxi4-1.primp-industries.com" ...
Executing script on "esxi4-3.primp-industries.com" ...

3. Verify iSCSI multipathing has been properly configured:

[[email protected] ]$ ./esxcli-automation.pl --hostlist hosts --cmd_option "swiscsi nic list -d vmhba33"
Executing script on "esxi4-1.primp-industries.com" ...

Now you will be able to automate any of the supported esxcli operations against multiple hosts!

In Part3, we will take a look at automating esxcli operations in a Windows environment using Powershell.

    I receive the following error:

    Undefined subroutine &vifplib_perl::CreateVIUserInfo called at line

    This is due the API change in 4.1

    Could you please the script?

      William, do you have a fox for this error
      Use of inherited AUTOLOAD for non-method vifplib_perl::CreateVIUserInfo() is deprecated at /usr/bin/esxcli-automation.pl line 69.
