This will take some time… vmkfstools “punches holes” inside your VMDK, e.g. deallocates all blocks that are filled with zeros, effectively shrinking your VMDK.

The Dell RACADM (Remote Access Controller Admin) utility is a command line tool that allows for remote or local management of Dell Servers via the iDRAC or DRAC. RACADM provides similar functionality to the iDRAC/DRAC Graphical User Interface (GUI). The Dell Chassis Management Controller (CMC) can also be managed remotely with RACADM.
RACADM commands can be run remotely from a management station and/or locally on the managed system.
RACADM commands allow you to view managed system information, perform power operations on the managed system, perform firmware updates, configure settings and more. Because RACADM is run from a command line interface (CLI), system administrators can create scripts that control and update Dell systems in a one-to-many fashion. See the links to the RACADM documentation at the end of this article for a complete listing of features for your product version.
Managed System – The Dell PowerEdge Server containing the iDRAC or DRAC, or the Dell Blade Chassis containing the Chassis Management Controller (CMC).
Management Station – A computer used for accessing the iDRAC, DRAC, or CMC remotely.
iDRAC – Integrated Dell Remote Access Controller. Available on newer and current generations of Dell PowerEdge Servers (11G and 12G).
DRAC – Dell Remote Access Controller. Available on older generations of Dell PowerEdge Servers.
The following RACADM utilities are available:
NOTES: Local RACADM is not required if you will be managing your server from a management station via Remote RACADM. Remote RACADM and Local RACADM cannot be installed at the same time on the same system.
Remote RACADM supports executing RACADM commands from a remote management station such as a laptop or desktop computer. It is available on the Dell OpenManage Systems Management Tools and Documentation DVD or at support.dell.com.
To download Remote RACADM:
Remote RACADM Download – Windows Operating System

SSH/Telnet/Serial RACADM (Firmware RACADM) is built into the iDRAC, DRAC or CMC firmware and there is no separate download or installation required. See your user’s guide for connecting via these methods.
Once connected via SSH, Telnet or Serial, type racadm help for the online help instructions.
NOTE: On some interfaces if you type racadm and press Enter, you will be taken to a racadm>> prompt. Commands can then be entered from this prompt without the “racadm” prefix. To exit the prompt, type quit or use Ctrl+C.
The following shows an example of a simple RACADM subcommand, getsysinfo, used with each RACADM utility. See the end of this article for links to documentation containing the full list of RACADM commands.
Remote RACADM commands must include the ip address or hostname of the idrac, and the idrac username and password.
racadm -r <ip address or hostname> -u <username> -p <password> <subcommand>
racadm -r 10.1.1.1 -u root -p calvin getsysinfo
NOTE: Remote racadm uses the web server SSL certificate of the iDRAC to authenticate the session. You will receive a warning message if certificates have not been configured or if the certificate is invalid. However, the command will execute normally following the message. If you wish to halt the command on certificate errors, use the -S option in the command. For information on configuring certificates on the iDRAC, see the user’s guide for your iDRAC linked at the end of this article.
You do not have to specify the ip address, username, or password in Local RACADM commands.
racadm <subcommand>
racadm getsysinfo
You do not have to specify the ip address, username, or password in Firmware RACADM commands.
racadm <subcommand>
racadm getsysinfo
or
racadm <Enter> – takes you to a racadm>> prompt
racadm>>getsysinfo
See the RACADM Command Line Reference Guide at the link below for detailed information on supported RACADM commands and features. This guide is available for iDRAC7, iDRAC6, and the CMC. For DRAC5, this information is combined with the DRAC5 User’s Guide.
See the Readme or Release Notes file posted alongside the guide for a complete listing of supported operating systems.
To locate a particular document, go to http://www.dell.com/esmmanuals , select Remote Access Controller (or Chassis Management Controller for CMC), then select your product version.

Configuration of HP ILO can be done using reboot of your HP server and Press <F8> to configure the ILO settings but you need a down time to your ESXi host and all the virtual machines running on it if it is a standalone host and no option to vMotion to other host. It is really a tough task to get downtime for your virtuali machines just for your ILO configurations like Reset ILO configuration, Reconfigure ILO IP address and reset ILO administrative password.
Now ILO configuration of ESXi host can easily be done without need of host restart using HP ESXi utilities.
HP ESXi Utilities Offline bundle for VMware ESXi 5.5 will be available as part of HP customized ESXi installer image but if it is not a HP customized ESXi image then you may need to download and install HP ESXi Utilities Offline bundle for VMware ESXi 5. It downloads the HP ESXi Utilities Offline bundle Zip file.This ZIp file contains 3 different utilities HPONCFG , HPBOOTCFG and HPACUCLI utilities for remote online configuration of servers.
HPONCFG can be used to set up and reconfigure the iLO (Integrated Lights-Out) management controller of a server.
HPBOOTCFG can be used to set up the boot configuration for the server.
HPACUCLI can be used in the configuration of HP Smart Array controllers and attached storage

How can I reset my MySQL password?
Following this procedure, you will disable access control on the MySQL server. All connexions will have a root access. It is a good thing to unplug your server from the network or at least disable remote access.
To reset your mysqld password just follow these instructions :
Because you are not checking user privs at this point, it’s safest to disable networking. In Dapper, /usr/bin/mysqld… did not work. However, mysqld –skip-grant-tables did.
For either method, once have received a message indicating a successful query (one or more rows affected), flush privileges:
FLUSH PRIVILEGES;
Then stop the mysqld process and relaunch it with the classical way:
sudo /etc/init.d/mysql stop
sudo /etc/init.d/mysql start
When you have completed all this steps ,you can easily access to your mysql server with the password you have set in the step before. An easy way to have a full control of your mysql server is phpmyadmin (www.phpmyadmin.net), software made in php that can give you a web interface that can be very usefull to people that havent got a lot of confidence with bash .To install phpmyadmin on you server you will need to have 4 things:
All packages can be found browsing synaptic.
Another way, purge
I also had some problems with mysql just not accepting my password. I tried the other way as well and it just ended up being difficult. I had not been able to use mysql so it was empty anyway. If this is also your case you may opt for the PURGE way. This removes every file related to mysql. Depending on your installation the packages might be diffrent, mysql-server in 6.10 is called mysql-server-5.0 as an example.
USE THIS AS A LAST RESORT METHOD, YOU WILL LOSE ALL YOUR MYSQL DATA
sudo apt-get –purge remove mysql-server mysql-common mysql-client
sudo apt-get install mysql-server mysql-common mysql-client
In the next step be sure to chance the your-new-password with the password you want!
mysqladmin -u root password your-new-password
sudo /etc/init.d/mysql restart
mysql -u root -p
You should now be logged in as root. Make sure to notedown your password! Thanks to Illuvator for posting this method in the ubuntu forum.
The Easiest Method
sudo dpkg-reconfigure mysql-server-N.N
dpkg -l | grep gcc | awk '{print $2}'
First erased the current update-alternatives setup for gcc and g++: (not Neccesery)
# sudo update-alternatives --remove-all gcc # sudo update-alternatives --remove-all g++
Install Packages
It seems that both gcc-4.3 and gcc-4.4 are installed after install build-essential. However, we can explicitly install the following packages:
sudo apt-get install gcc-6 g++-6
Install Alternatives
Symbolic links cc and c++ are installed by default. We will install symbol links for gcc and g++, then link cc and c++ to gcc and g++ respectively.
#sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 10 sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-6 20 #sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.8 10 sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-6 20 sudo update-alternatives --install /usr/bin/cc cc /usr/bin/gcc 30 sudo update-alternatives --set cc /usr/bin/gcc sudo update-alternatives --install /usr/bin/c++ c++ /usr/bin/g++ 30 sudo update-alternatives --set c++ /usr/bin/g++
Configure Alternatives
The last step is configuring the default commands for gcc, g++. It’s easy to switch between 4.3 and 4.4 interactively:
sudo update-alternatives --config gcc
sudo update-alternatives --config g++
gcc -v
g++ -v
