service tag must be reset to its original value for XenServer to function.
Download the latest asset.com utility from ftp.us.dell.com/utility. In the
DOS prompt, type asset.com /s <service tag>.
Resetting the Root Password
If you lose or forget the root password, you can reset it using the XenServer
Dell Edition Recovery Media. For more information, see "Using the Recovery
Media" on page 46.
To reset the root password:
1
Boot using the recovery media.
2 Select your preferred key map.
3 Select Reset the password for an existing installation .
4 Follow the on-screen instructions.
Updating the XenServer Image to a new Version
The XenServer Dell Edition differs from the standard editions in the way it
updates drivers and other components. There is no provision to individually
load updated drivers. You can only apply update packages provided by Citrix.
Updates are provided as downloads on the Citrix XenServer Dell Edition website
at citrix.com/xenserver/dell. When an update is available, download the update
package and save it on a removable storage device, such as a USB stick.
To install updates using the XenServer local console:
1
Select Backup, Restore and Update from the local console menu.
2 Select Apply Update and follow the prompts.
NOTE: You may be required to manually enter the filename of the update file.
3 Reboot the system.
To install updates using XenCenter, ensure that you are using the Automatic
mode. For more information, see the Updating Servers section in the
XenCenter online help.
