How to Re-start VMWare Hostd service ?

service mgmt-vmware restart

when you make change from command line, those changes might not be visible in Virtual center, to make them visible re-start of hostd is recommended.This restart process re-reads esx.conf file


E.g. => service –status-all

E.g. => service vmware-vpxa status

Before we do this, we need to understand why are we actually enabling disk shares. Since in ESX environment we have multiple VM’s accessing the same VMFS volume and in that in case, you need to prioritize any of the VM, it is recommend practice to enable disk shares for that VM.

How to enable disk shares to prioritize virtual machines

  1. Start a VI Client and connect to a Virtual Center Server.
  2. Select the virtual machine in the inventory panel and choose Edit Settings from the right‐button menu.
  3. Click the Resources tab, and click Disk.
  4. Right‐click the Shares column for the disk you want to modify, and select the required value from the drop‐down menu.

VMware Infrastructure 3: Advanced Technical Design Guide

Posted by Preetam on September 2, 2007

Three great guys and one great way of sharing knowledge. I’ve just read finishing 110 pages of this book. At all point I felt someone is talking to me, explaining me and that as well filled with great humor. My words will fall short for this book. This book reaches a cult status in my heart for one  great reason and that is book comes free. I’m not sure about the entire book, after reading this book I feel very few of us will resist buying this book.

How to set ESX Host into maintenance mode from Service console

Posted by Preetam on August 24, 2007

Below is the command which you will have to execute from SVC Console to enter host into maintenance mode

vimsh -n -e /hostsvc/maintenance_mode_enter

To exit maintenance mode

vimsh -n -e /hostsvc/maintenance_mode_exit

Now next question is how I check whether host is in maintenance mode.Here is it…

vimsh -n -e /hostsvc/runtimeinfo | grep inMaintenanceMode | awk ‘{print $3}’


For more information please visit http://www.xtravirt.com and under section white papers. I’ll rate this site 5-Stars, anyone who wish to excel in VMWare.
