Cause

This issue is encountered if a control character is encountered for any of the Hardware components.

AKD reads the hardware configuration and reads the details like Serial no. , FRU part no. etc,

If these details are corrupted and an illegal control character is seen by AKD, this kind of error message is seen.

This is a known issue with older AK firmware - older than 2013.1.5.4

fru-part string M39à^D^DG70BH0-YK0 <<<<<

Solution

1. Replace the component seen with control character.

2. Upgrade the Appliance Firmware Release to the latest which fixes this bug.
