Error: "Blocked Mailbox......!!" at VMkernel Load Time

Details

When the VMkernel is loading, I get repeated error messages saying "Blocked Mailbox......!!" What is wrong?

Solution

This problem has been reported on some Dell servers with PercRAID controllers and some servers with MegaRAID controllers. It happens if you assign about 256MB of memory to the console operating system.

If you encounter the problem, take the following steps:

  1. Reboot the computer. When LILO comes up, choose to boot the Linux-UP kernel.
  2. From your management workstation, start your Web browser and log in to the VMware Management Interface as root.
  3. Click Configure System, then click Update Boot Configuration.
  4. Edit the existing configuration, or create a new one, and set the memory for the console operating to a value that is not in the range of 241MB-271MB to avoid the problem.
