Messaging Gateway Virtual Machine Kernel Panics After Update to 9.5.2
Last Updated April 18, 2012
After updating the SMG virtual appliance to v9.5.2 the virtual machine (VM) fails to restart. Looking at the VM console indicates that the VM is unable to reboot due to a kernel panic.
Sample errors and screenshot:
Mounting root filesystem.
mount: could not find filesystem '/dev/root'
setuproot: moving /dev failed: No such file or directory
setuproot: error mounting /proc: No such file or directory
setuproot: error mounting /sys: No such file or directory
switchroot: mount failed: No such file or directory
Kernel panic - not syncing: Attempted to kill init!
This can occur when not using the LSI SAS or LSI Parallel controller for the virtual machine and primarily affects virtual machines that have been in operation since SMG version 8.0.2 or earlier.
Set the VM SCSI controller to LSI SAS or Parallel prior to performing the update. Resetting the VM SCSI controller to LSI after the update will not address the issue. If you have updated to SMG 9.5.2 with a VM configuration using a different SCSI controller and your installation is exhibiting this issue, you will need to perform one of the following:
If you took a snapshot prior to the update (recommended best practice)
Roll the virtual machine back to a snapshot taken prior to the update
Reset the SCSI controller to LSI SAS or LSI Parallel
Run the update to v9.5.2 again.
If you do not have a snapshot and the appliance is scanner only
Remove the Scanner appliance from the Control Center Administration->Configuration page
Rebuild the VM using the Symantec SMG v9.5.2 OVF available from Symantec Fileconnect
Add the updated scanner back to the Control Center via the Administration->Configuration page
If the affected virtual appliance is the Control Center and you do not have a snapshot
Rebuild the VM using the Symantec SMG OVF version that matches your most recent backup
Restore the most recent backup to the view virtual machine
Update to SMG version 9.5.2
Note: If you are not seeing LSI SAS a selectable option for the VMware SCSI controller you will need to convert the virtual hardware version to 7. For steps on this process, please refer to the following KB:
