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.

PuTTY SSH terminal session

  • logged in as root to ssh terminal session

    logged in as root to ssh terminal session

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>
  • change folders

change folders

example :- cd /vmfs/volumes/datastore1/isos
type cd /vmfs/volumes/datastore1/isos in the SSH session window.
  • md5sum

md5sum

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
  • MD5 Checksum Signature

MD5 Checksum Signature

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: 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.

Prerequisites

  • An original operating system CD-ROM/DVD-ROM
2

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 ISORecorder31×64.msi

  • Welcome to the ISO Recorder Setup Wizard

Welcome to the ISO Recorder Setup Wizard

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.
  • Completed - Finish

Completed - Finish

Select Finish to complete the operation. The ISO image file has been created.

4

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.

  • MD5 SHA-1 Checksum Utility

MD5 SHA-1 Checksum Utility

Double-Click and start the MD5 & SHA-1 Checksum Utility application. Click browse and select your freshly created ISO image file.
  • MD5

MD5

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, 2012
In 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.

  • Using the VMware vSphere Client, Login and Connect to the ESXi server

Using the VMware vSphere Client, Login and Connect to the ESXi 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

  • storage device to configure as SSD

storage device to configure as SSD

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.

putty SSH terminal session

  • logged in as root to ssh terminal session

logged in as root to ssh terminal session

4. Create a new SATP rule

At the console or SSH session type the following commands to create a new SATP rule.

esxcli storage nmp satp rule add --satp VMW_SATP_LOCAL --device mpx.vmhba1:C0:T0:L0 --option=enable_ssd

using the device name recorded in Step 2 above. The console will return a new line. To check the rule has been created correctly type the following commands

esxcli storage nmp satp rule list | grep enable_ssd

the following screenshot should be displayed

  • Confirmation of rule creation

Confirmation of rule creation

confirming the creation of the rule.

5. Claim storage device

At the console or SSH session type the following commands

esxcli storage core claiming reclaim -d mpx.vmhba1:C0:T0:L0

using the device name recorded in Step 2 above.

I have seen the following error messages when trying to claim devices, either restart the server or use the “unclaim” device command.

  • Unable to unclaim path vmhba1:C0:T0:L0 on device mpx.vmhba1:C0:T0:L0. Some paths may be left in an unclaimed state. You will need to claim them manually using the appropriate commands or wait for peri

Unable to unclaim path vmhba1:C0:T0:L0 on device mpx.vmhba1:C0:T0:L0. Some paths may be left in an unclaimed state. You will need to claim them manually using the appropriate commands or wait for peri

you can unclaim the device by specifying the device name.

esxcli storage core claiming unclaim --type device --device device_name

6. Reload the claim rules

I usually reload the claim rules and run the rules using the following commands:

esxcli storage core claimrule load
esxcli storage core claimrule run

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

esxcli storage core device list --device=mpx.vmhba1:C0:T0:L0

The following output will be displayed for the device.

  • local device tagged as SSD

local device tagged as 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.

  • storage device to configure or tagged as SSD

storage device to configure or tagged as SSD

In my next Article, I show you how to configure Host Cache Configuration.
