Monitor your ESX at free of cost

We can monitor the ESX host and its VM from your desktop without any additional investment. SolarWinds offers free monitor tool. Sadly, they are allowing us to monitor only one host. If need more than that, please pay to them :).

Here is the link for downloading the Tool: http://www.solarwinds.com/products/freetools/vm_monitor.aspx

Download this tool, install on your desktop (mine is Windows XP SP2). In the configuration setting, please enter your ESX host IP address and select the SNMP Version. It selecte SNMPV2 by default and enter the community string if SNMP related NMS configured. Otherwise, leave it to "public"

The following steps only for if SNMP not enabled in the host.

Connect the ESX thru SSH or service console.

SNMP configuration file is: /etc/snmp/snmpd.conf

To start the service: /etc/rc.d/init.d/snmpd start (OR) service snmpd start

Use following command to start the SNMP service after every reboot

chkconfig snmpd on

Now, dont forget to do this....

esxcfg-firewall -q snmpd (To check the SNMP is enabled or not, by default it is disabled)

esxcfg-firewall -e snmpd (Enabling the SNMP service in the ESX firewall)

Now, you can connect the ESX server and view its VMs status.

There you go!!!!

vCenter Reinstallation after 60-Days trial expires without losing Database Contents

Many of us still evaluating the vSphere and vCenter in our test environments. Sometimes, it takes more than 60 days to evaluate where trial edition expires.
We can't extend the trial edition in ESX host, either we have to reinstall it or license it. vCenter also have to follow the same way as ESX does. But, here we can keep old database contents as it is when you reinstall the vCenter software.

This document using vCenter 4.0 and SQLEXPRESS 2005 (built in) database. At the time of installation of vCenter 4.0, it installs SQLEXPRESS 2005 by default unless any other Database specified. Mostly, we are using built-in database is SQLEXPRESS 2005 for testing environment.
When you install vCenter 4.0, it installs SQLEXPRESS 2005 and creates a database called "SQLEXP_VIM". You can view this thru SQL Server Configuration Manager console.

Set VLAN ID to IPMI Address in Nutanix

The IPMI is remote management interface like as HP iLO, DELL DRAC. During the Nutanix cluster deployment, it is not possible to mention the VLAN ID of the IPMI's IP Address. This need to be entered thru command line via ESXi host or Windows Hyper-V. This article talks about ESXi host only.

Login to ESXi thru SSH client. Run the following command to enter the VLAN ID (we assume that you already configured IP Address)

~ # /ipmitool lan set 1 vlan id 333

~ # /ipmitool lan print1

Changing Thin to Thick disk and vice-versa

You can change the existing Virtual Hard disks (VMware based) from Thick to thin and vice-versa. This can be achieved by either using VMotion/SVMotion or command line tool called "vmkfstools". Using VMotion/SVMotion is required a valid license. Select “Migrate” and choose “Change Datastore” and select the Disk format.

If you don’t have a VMotion/SVMotion license, use the following command to achieve the same.

From Thick to Thin:

vmkfstools –i "Thickdisk.vmdk" -d thin "Thindisk.vmdk"

It will start to clone to virtual hard disk in Thin Provision method. After completed, you can attach this disk with VM and power it on. If all looks good, you can delete the original thick disk from the data store.

Use the following command to see real-time usage of thin disk:

du –h "Thindisk.vmdk"

You can notice the big difference of disk usage between of Thin and Thick format disks.

From Thin to Thick:

vmkfstools –i "Thindisk.vmdk" -d zeroedthick "Thindisk…
