Once connected to the “default hypervisor home page”, click the Inventory icon, to see the server’s Inventory.
Click the Configuration Tab.
Click Security Profile, followed by Properties
The Security Service Properties will be displayed.
Click the SSH label followed by Options button, you will notice the daemon service is currently stopped, this is the default.
The SSH (TSM-SSH) Options will be displayed. Click Start to start the SSH deamon. You can change the options here if you wish to Start and stop the SSH daemon service with the host, or Start automatically if any ports are open, and stop when all ports are closed. Check with your Security IT Policy which is best for you. Opening SSH ports long term can be considered a security risk.
You will notice the SSH Daemon Status has changed to Running
. Click OK to continue, and Click OK to return to Inventory.
. Click OK to continue, and Click OK to return to Inventory.
Confirm using PuTTY, you can connect to the server successfully.
In vSphere 4 1, 5.0 and 5.1, when you have enabled Remote SSH management of hosts from the vSphere Client, you may notice that that a Configuration Issues warning yellow box appears on the Summary page of the host ESXi server.
This Configuration Issues warning yellow box only appears when Remote SSH and/or ESXi shell has been enabled.
Please refer to my Andysworld! Article on HOW TO: Suppress Configuration Issues and Warnings Alert displayed in Summary status for ESXi 4.1 U2 or ESXi 5.0 after enabling SSH or ESXi Shell
Congratulations, you have successfully Enable SSH Remote Access on a VMware vSphere Hypervisor 5.1 (ESXi 5.1)

Connect to the VMware vSphere Hypervisor 5.1 (ESXi 5.1) or vSphere vCenter Server using the vSphere Client
Please refer to my EE article on HOW TO: Connect to the VMware vSphere Hypervisor 5.1 (ESXi 5.1) using the vSphere Client
Once connected to the “default hypervisor home page”, click the Inventory icon, to see the server’s Inventory.
Right Click on the datastore. In this example the datastore name is datastore1. This is the default name given to the datastore on installation, it can be changed. Please refer to Step 4 Conducting a simple task using the VMware vSphere Client in my Andysworld! article HOW TO: Connect to the VMware vSphere Hypervisor 5.1 (ESXi 5.1) using the vSphere Client
Right Click the datastore name ‘datastore1’ and select Browse Datastore.
The Datastore Browser window will be opened, and you can browse the files and folders, that are located on the datastore. If no virtual machines or files are present, this will be empty. To organise your ISO image files, we would recommend you create a folder called isos. Either select the ‘Create A New Folder’ icon, on the ribbon bar, or right-click in the right-hand empty panel, and select New Folder.
Enter folder name – isos, and Click OK
The isos folder will be shown in the datastore
Select and Double-Click the isos folder to change folders.

Uploading the ISO CD-ROM/DVD-ROM image to the datastore ‘datastore1’
Please refer to my Andysworld! Article HOW TO: Create an ISO CD-ROM/DVD-ROM image (*.iso), and MD5 checksum signature, for use with VMware vSphere Hypervisor 5.1 (ESXi 5.1)
Select the ‘Upload files to this datastore’ icon on the ribbon bar.
Select Upload File…
Browse to location of the stored iso image file on your computers hard disk, in my example, we have stored the iso image file, in c:isos, from our previous EE Article, the filename is Ubuntu 12.10 amd.iso. Click OK to continue and upload the file.
Select Yes to the Upload/Downloading Operation Warning.
The ISO image file, e.g. Ubuntu 12.10 amd.iso will be upload to datastore1 in the folder isos. This can take several minutes depending upon size and speed of connection to the VMware vSphere Hypervisor 5.1 (ESXi 5.1) host server.
datastore1 with the ISO image uploaded and stored in the folder isos. Click the X in the top right hand corner to Close the Datastore Browser.

Confirming the upload of the ISO image file has been transferred successfully using the MD5 checksum signature
To complete the following step SSH must be enabled and running on your VMware vSphere Hypervisor 5.1 (ESXi 5.1) host server, if SSH is not running you will receive a connection refused message.
To Enable SSH on your VMware vSphere Hypervisor 5.1 (ESXi 5.1) host server, please see my Andysworld! article HOW TO: Enable SSH Remote Access to a VMware vSphere Hypervisor 5.1 (ESXi 5.1)
Connect to the VMware Hypervisor ESXi server via SSH. Using PuTTY a free telnet and SSH client or another SSH client Login and Connect to the VMware Hypervisor ESXi server, using IP address or hostname of the VMware Hypervisor ESXi server, using root username and password credentials. This can also be performed if you have access to the console.
You will need to change folder or directories to the location of the iso image file. The VMware VMFS datastores are mapped here /vmfs/volumes. Use the following command to change to the datastore1 datastore and isos folder.
cd /vmfs/volume/<datastore name>/<folder name>
cd /vmfs/volume/<datastore name>/<folder name>
example :- cd /vmfs/volumes/datastore1/isos
type cd /vmfs/volumes/datastore1/isos in the SSH session window.
type cd /vmfs/volumes/datastore1/isos in the SSH session window.
When you have successfully changed folders to the location of the isos image file which has been uploaded, use the following command to check the MD5 checksum signature.
md5sum <filename>
example md5sum Ubuntu 12.10 amd.iso
md5sum <filename>
example md5sum Ubuntu 12.10 amd.iso
type md5sum Ubuntu 12.10 amd.iso in the SSH session window. After several minutes, and the time taken, depends on the size of the ISO image file, and speed of host processor and storage, a MD5 checksum signature will be displayed. The number displayed next to the filename – 7ad57cadae955bd04019389d4b
9c1dcb – is the MD5 checksum signature. Compare this number with the original number computed before the ISO image file was uploaded, if they match, the transfer was successful. If they do not match, repeat Step 2 above.Congratulations, you have successfully uploaded an ISO CD-ROM/DVD-ROM image to a VMware datastore for use with VMware vSphere Hypervisor 5.1 (ESXi 5.1) using the vSphere Client, and checked its MD5 checksum signature is correct.

HOW TO: Install and Configure VMware vSphere Hypervisor 5.1 (ESXi 5.1)
HOW TO: Connect to the VMware vSphere Hypervisor 5.1 (ESXi 5.1) using the vSphere Client
In this series of basic VMware articles for the Novice, I’ll be showing you the basic VMware skills required to install, configure and deploy virtual machines using VMware’s FREE VMware vSphere Hypervisor (ESXi).
This article will show you how to create an ISO CD-ROM/DVD-ROM image (*.iso), and MD5 checksum signature, for use with VMware vSphere Hypervisor 5.1 (ESXi 5.1).
What is an ISO? (Andy’s Laymen Definition)
An ISO is an image or bit copy of a CD-ROM/DVD-ROM, the ISO is a file, similar to a compressed archived file, this *.iso file contains the data from a CD-ROM/DVD-ROM. The ISO file is a virtual CD-ROM/DVD-ROM. Using an *.iso file has many advantages, some are listed below:-
- The original CDROM/DVD-ROM can be stored securely, and is no longer required, after an ISO image has been created.
- Multiple virtual machines can use the same *.iso concurrently.
- Computers without a CD-ROM/DVD-ROM reader can use the data stored on the *.iso file.
- Installing OS (operating systems) or transferring data is faster.

Install ISO Recorder
Download ISO Recorder from http://alexfeinman.co/isorecorder.htm We like to use ISO Recorder, because it is a small lightweight application, which integrates into the shell of your OS (operating system). e.g. you right click the CD-ROM/DVD-ROM reader and the option is there to create an ISO.
There are several versions of ISO Recorder to download, ensure you download the correct version for your OS, and the correct version for your processor, as there are 32-bit and 64-bit versions available.
After you have downloaded the correct version, Double-Click the installer program (*.msi) you have download, we will install the Windows 7 64 bit version, which has the filename ISORecorder31x64.msi
At the Welcome to the ISO Recorder Setup Wizard dialogue page, Click Next and continue
At the Select Installation Folder dialogue page select the defaults, and Click Next to continue.
Confirm installation at the Confirm Installation dialogue page, and Click Next to continue.
The installer will Complete the software installation, it only takes a few seconds to complete. Click Close to complete the installation.

Create an ISO image file
Select My Computer.
Insert an original operating system CD-ROM/DVD-ROM into your optical media device. In this example, we are using an Ubuntu 12.10 DVD-ROM.
Right-Click the CD-ROM/DVD-ROM, and select Create image from CD/DVD.
Select a filename and destination folder on your computers hard drive to store the ISO image file and Click Next to continue, this will create an ISO image file.
The data will be copied from the CD-ROM/DVD-ROM, and the ISO image will be created. This can take several minutes to complete.
Select Finish to complete the operation. The ISO image file has been created.

Creating a MD5 checksum signature of the ISO image file
We will use the MD5 & SHA-1 Checksum Utility to create a MD5 checksum signature for our freshly created ISO image file. This is important, so we can compare these signatures, once we have completed the transfer to our VMware host servers, and confirm the ISO image file has not been corrupted in transfer.
Double-Click and start the MD5 & SHA-1 Checksum Utility application. Click browse and select your freshly created ISO image file.
Shortly after selecting the ISO file, the application will start calculating the MD5 and SHA-1 checksums for the file, this can take a few minutes depending upon the size of the ISO image file, which needs to be read.
The MD5 checksum for my Ubuntu 12.10 amd.iso is:-
MD5 Checksum: 7AD57CADAE955BD04019389D4B9C1DCB
SHA-1 Checksum: 8618058554FFD11E317356EC25885BCB8C1D0B36
Generated by MD5 & SHA-1 Checksum Utility @ http://raylin.wordpress.com/downloads/md5-sha-1-checksum-utility
Please note the MD5 checksum value for use with the VMware vSphere Hypervisor 5.1 (ESXi 5.1)
Congratulations you have successfully created your first ISO (*.iso), and created a MD5 checksum signature for use with VMware vSphere Hypervisor 5.1 (ESXi 5.1).

HOW TO: Tag and Configure a storage device as a Solid State Disk (SSD) in VMware vSphere 5.0 or 5.1 (ESXi 5.0 or ESXi 5.1)
Thursday, November 29th, 2012In VMware vSphere 5.x (ESXi 5.x) there is a new feature called Host Cache Configuration. This new feature allows the VMware vSphere Administrator to configure the VMware vSphere 5.x (ESXi 5.x) host server to use a cache on a Solid State Disks (SSD) for the virtual machine’s swapfile for better performance, because the SSD has much faster latency than a traditional mechanical disk. This is also known in VMware Administrator circles as Swap to Host Cache or Swap to SSD. Once Host Cache Configuration has been enabled, the virtual machines will be swapping to SSD, but this swapfile is not a true swap file, and the entire virtual machine swap file (.vswp) is not stored on the SSD.However, not all SSD devices are correctly tagged as SSD. This tutorial shows how to tag a Non-SSD storage device as SSD, if you want to experiment with Host Cache Configuration but do not have a SSD to hand. This is not supported by VMware, tagging a non-SSD as a SSD.
The same procedure can be followed to tag a SSD, correctly, if it’s not recognized by the VMware ESXi server.
With the current fall in prices for consumer SSDs, it can give a real performance boost to a VMware ESXi 5.x server which is short on memory. Consumer SSDs e.g. Kingston SSDNow V+200 Drive Model SVP200S37A/60G are generally cheaper than server memory. We recently purchased this model for £29.99 GBP.
The commands we will be using in this Tutorial, are the esxcli commands, these commands can be executed on the ESXi shell, through the vMA or PowerCLI esxcli remote version. In this tutorial I’ll be logging into the ESXi server, and executing the commands on the ESXi shell.
-
1. Connect to the VMware vSphere Hypervisor (ESXi) or VMware vSphere vCenter Server
Using the VMware vSphere Client, Login and Connect to the ESXi server, using IP address or hostname of the ESXi server, using root username and password credentials. If you have a VMware vSphere vCenter server, you could also specify IP address or hostname of the vCenter server.
-
2. Check and record the storage device name to be tagged as a SSD
Check there is a VMFS volume already formatted on the storage device, you want to present to the Host ESXi server, as a SSD and record the device name for later in Step 4.
Select Host > Configuration > Storage
In the example above, the local storage device mpx.vmhba1:C0:T0:L0 is a local disk, formatted with the datastore name datastore1 as VMFS5. Record the storage device name mpx.vmhba1:C0:T0:L0.

3. Logon to ESXi console (shell) via PuTTY
Using PuTTY a free telnet and SSH client or another SSH client Login and Connect to the VMware Hypervisor ESXi server, using IP address or hostname of the VMware Hypervisor ESXi server, using root username and password credentials.
-
4. Create a new SATP rule
At the console or SSH session type the following commands to create a new SATP rule.
confirming the creation of the rule.
-
5. Claim storage device
At the console or SSH session type the following commands
I have seen the following error messages when trying to claim devices, either restart the server or use the “unclaim” device command.
you can unclaim the device by specifying the device name.
-
6. Reload the claim rules
I usually reload the claim rules and run the rules using the following commands:
-
7. Confirm device is Tagged as SSD
Use the following command at the console, to check if the device has successfully been tagged as a SSD
Check the output states “Is SSD: true”
You have successfully configured and tagged a local device as a SSD. If you now repeat Step 2 above, you will see the device now states SSD.
In my next Article, I show you how to configure Host Cache Configuration.
