Products

• VMware vCenter Server 8.0

Issue/Introduction

The VAMI is unable to detect the ISO file after it has been attached via the CD/DVD option on the vCenter VM.

• The ISO is not detected via the CLI.

• It is also not visible in the VAMI under:
  Updates → Available Updates → Check Updates → Check CD-ROM.

Environment

vSphere 7.0

vSphere 8.0

Resolution

1. Attach the relevant ISO from the vCenter VM

• Select: Datastore ISO file from VM edit settings
• Tick the checkbox: Connect At Power On and save the settings

2. Login to vCenter CLI
   
   
3. Perform the following commands to mount the ISO

     mount /dev/cdrom /mnt/cdrom/

         Example output:

         mount: /mnt/cdrom: WARNING: device write-protected, mounted read-only

     4. To list the mounted ISO, you may run the command:

         ls /mnt/cdrom/

     5. To verify that you see the ISO mounted on the vCenter, please run the command:

         df -h

    Example output:

        /dev/sr0       6.3G  6.3G     0 100% /mnt/cdrom

6. Exit from SHELL with the command, exit.

         If it’s closing the session, run this command to change from using the BASH Shell to the Appliance Shell:

         chsh -s /bin/appliancesh root

         Log out and log in again for the changes to take effect.

     7. Stage the packages located in the .ISO file mounted to the vCenter Server VM:

    software-packages stage --iso --acceptEulas

     8. After the staging completes, list or install the staged packages:

1. 1. To verify the version of the mounted ISO:
      
      software-packages list --staged
      
      
   2. To install the staged packages:
      
      software-packages install --staged
      
      

     9.  Once completed, an output will state: "Packages upgraded successfully, Reboot is required to complete the installation”.

    10. If the patch installation requires a reboot of the appliance, run the following command to restart the appliance:

     shutdown now -r "patch reboot"
