Oracle Kills Virtual Iron Brand and Fires Employees

Wow, I thought this was crazy.. Virtual Iron was gobbled up by Oracle a couple months ago and I know a lot of us were wondering what was in store for Virtual Iron.. well, the future isn’t a good one for them. It looks like Oracle has killed the Virtual Iron brand, assimulating their technology and moving on (yes, that was a geeky Star Trek reference hehe). Read more about it at these links:

Oh, and if you need a VMware design/demo/quote to replace Virtual Iron in your environment, just let us know! ;-)
UPDATE: VMware has also provided special promo pricing for ex-Virtual Iron customers to move over to VMware! See the details here:

How To Collect Data From a Fibre Channel (FC) Switch

Sometimes you will be asked by either the manufacturers support or perhaps by Lewan for data from your Fibre Channel switch. Here is how you can gather that information in a format that helps support and/or Lewan:

Brocade – How-To Collect a “supportshow” from a Brocade Switch from a Windows Host with HyperTerminal
Follow these steps:

  1. Start the HyperTerminal program by selecting Start -> Programs -> Accessories -> Communications -> HyperTerminal.
  2. Make a new connection and select a name and icon for the connection.
  3. A “Connect to” window is displayed.
  4. Change the Connection using modem to TCP/IP (Winsock) and enter the IP address of the Brocade switch.
  5. Click the OK button.
  6. Log in to Brocade switch (default user: admin/default password: password), and then start to capture text. Select Transfer -> Capture text -> File C:supportshow.wri.
  7. Run the Brocade supportshow command.
  8. After the command completes, stop the “capture text” process (Transfer -> Capture text -> Stop).
  9. After completing this for all switches in all related fabrics, type quit and close the HyperTerminal session.

Cisco Support Logs

To capture support logs for a Cisco FC switch, following these instructions:

1) For firmware 1.2(x) and above telnet to the switch and open a capture session.
2) Run the following commands:
    term len 0
    show tech-support details
3) For firmware 1.0(4):  There is not a single command like a supportshow or data collection. There are two ways to get the outputs needed to troubleshoot most Cisco switch issues. Contact Lewan for additional information.

McDATA Switch Data Collection

In order to collect data from a McDATA switch being managed by McDATA’s EFCM utility, follow these instructions:

  1. Select the switch that you want to collect data from.
  2. Select Maintenance and then Data Collection.
  3. Enter a file name to call the file and then select save. Note the directory where the data is saved.  Once you select save, the data collection takes over and the files is downloaded to the local PC and stored in the directory specified.

How to collect switch information and related data from a McDATA DS-16M, DS-32M or another switch with EWS:

These switches (also known as ES3016 and ES3032)  have an Embedded Web Server (EWS) GUI. You can access this through a web browser by entering the IP Address in the URL address line  (that is, http:/10.14.1.92).  Once you have logged in you can run a script that collects switch information including: Network Info, Operating Parameters, Zone Info, Port Login Data, Port Data and Port Types, and Switch Status.

Note:  These model switches do not support serial port connectivity for information retrieval.

To collect this information, follow these steps:

  1. Once you have logged in to the EWS GUI, click on ” Operations ” from the left frame of the EWS GUI.
  2. Click the third tab called “Maintenance.”
  3. Click the secondary tab labeled Product Info.
  4. Click Product Information. This will generate a report.
  5. Click “File” on the web browser toolbar and select “Save As” to save the .txt file with either the default name or one that you rename it to. Save it on the desktop or to a directory where you can locate it so that you can email it to Technical Support.

To locate the switch firmware revision, follow these steps:

  1. Click “View” from the left frame of the EWS GUI.
  2. Select Unit Properties. The last entry of that page has the firmware level.

Oracle Buys Virtual Iron

I guess when Oracle bought Sun, they had some more money laying around.. they also bought a Xen Hypervisor offshoot based virtualization company called Virtual Iron.

http://www.oracle.com/us/corporate/press/018535
http://www.oracle.com/virtualiron/index.html

It’ll be interesting to see what they do with it, now that Oracle has Sun’s virtual offerings as well as Virtual Iron’s offerings..

Using USB Devices in Virtual Machines on VMware ESX

I’ve been getting this question a lot lately – “Can I use USB devices or dongles inside a Virtual Machine on ESX?”

The out-of-the-box answer is No. USB devices are not supported within the VM on ESX 3.5. That being said, there are a few companies that have gotten excellent reviews and are very popular on the VMware Community Forums that provide USB functionality.

The most popular way of presenting USB devices in Virtual Machines on ESX that I’ve heard/seen is from Digi International, which has a product called AnywhereUSB. Follow the link for additional info on the product.
They have also published a VMware Branded Technical Note (whitepaper) entitled VMware ESX Server: Using AnywhereUSB to Connect USB Devices

FabulaTech is another popular way. A good post regarding it can be found here:
http://www.ntpro.nl/blog/archives/897-Passing-USB-devices-to-the-Virtual-Machines.html

Update to the post:
I came across a recent post over at VMetc mentioning a couple more temporary plus permanent options for using USB over IP:
http://vmetc.com/2009/03/11/connecting-a-usb-device-to-an-esx-hosted-vm/

A few other links of companies that have gotten good reviews to allow USB access in VM’s:
http://www.kernelpro.com/usb-over-ethernet.html (Inexpensive, starts at $89!)
http://usbip.sourceforge.net (Open Source Project for USB over IP)

How to configure OpenFiler v2.3 iSCSI Storage for use with VMware ESX

On my to-do list was to write up a How-To on using OpenFiler iSCSI storage appliance with VMware ESX. The OpenFiler appliance is a free appliance that you can use to turn local storage into an iSCSI target. Well, Simon over at TechHead in the UK did a bang up job (that’s London speak!) with a How-To detailing installing the OpenFiler software and using it with ESX.

http://www.techhead.co.uk/how-to-configure-openfiler-v23-iscsi-storage-for-use-with-vmware-esx

I’ve heard great things about OpenFiler from our customers who are using it. Keep in mind, you’ll want to keep OpenFiler in DR environments or Test/Dev environments as there is some limits on performance. But those who are looking for a free iSCSI target or appliance, it’s a good one.

You might also check out our other post on some of the other common iSCSI appliances, very similar to OpenFiler:

VMware vCenter Mobile Access Technology Preview

I ran across this on another blog surfing for something which I’ve since forgotten.. ;-) I thought this was pretty neat. It’s the Technology Preview of a new feature for VMware vCenter called vCenter Mobile Access. Here’s the link:
http://communities.vmware.com/community/beta/vcmobileaccess

They even have a video showing it “in action” (just turn down your speakers though, the music is horrible IMO). There’s a link near the bottom of the page titled “How Will I Connect to This Thing” which is interesting too, especially since most people can’t get to their vCenter server from outside their corporate LAN, well without VPN or something.

This is VMware’s own product that is very similar to: http://www.roveit.com/mobileadmin/overview/
and http://lostcreations.com/vmm

How-To: Setup SNMP on ESX 3.5 Servers

To monitor your ESX 3.5 server by using SNMP, we need to enable SNMP on ESX before adding it to your monitoring software. This How-To will show you the steps involved.

 

Log Into ESX Server

media-1235427473105.png

Log into your ESX Server either through SSH or through the console of the server.

Use Nano to Edit Snmpd.conf

media-1235427595706.png

Use Nano (which is a notepad like text editor) to edit the file /etc/snmp/snmpd.conf file by using the command:
nano /etc/snmp/snmpd.conf

Add SNMP Community to Config File

media-1235427774660.png

Use the arrow keys to go down to the section “rocommunity public”. Replace “public” with your community string for your environment (1). Then use “Ctrl+X” to exit out of Nano. You’ll be asked if you would like to save. Type in “y” for yes and hit enter. Press enter again when confirming the filename to save as.

Enable SNMP to Start Automatically After a Reboot

media-1235428097675.png

Since SNMP is not started by default, you’ll need to type in this command to ensure it will be started after a reboot of the ESX server. The command is:
chkconfig snmpd on

Enable SNMP Through the ESX Firewall

media-1235428204838.png

We’ll need to allow SNMP traffic through the built-in ESX firewall. To do this, type in the following command:
esxcfg-firewall -e snmpd

Start the SNMP Service

media-1235428286191.png

Now we’re ready to start the SNMP service. Type in:
service snmpd start

Ready for Monitoring

At this point, SNMP is enabled on your ESX 3.5 server and you can monitor it using your SNMP monitoring software! Happy monitoring!

Timekeeping best practices for Linux

If you’ve ever battled with time-drift with Linux virtual machines, this KB article is for you.

http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1006427

The KB provides a table of Linux distro’s and versions, along with the appropriate kernel parameters to help make them keep time properly when virtualized. Also includes NTP config options to help NTP cope with time jumps.
