Error

drmach: Cannot unconfigure I/O board: n/w or tunnel switch failed

Description

The I/O board cannot be configured because the network or tunnel switch failed.

Recovery

Check to ensure that there is at least one other I/O board in the system to take over the IOSRAM functionality of the specified board. If another I/O board is not available, you must configure an additional I/O board into the domain. If the system booted off of a device attached to the I/O board that is being unconfigured, then an addtional I/O board will not solve this error. If an additional I/O board is available and if this error persists, then check for failures with the IOSRAM driver or the MAN driver.
