Cause:

 

 

During a fresh installation of PowerPath few error messages will be logged in the /var/adm/messages which can be ignored.   
    - The MPAPI I/o error, PPME_PowerPath error(0x8100) errors will appear only during fresh installation of PowerPath, where PowerPath modules are not present already   
    - the "signature verification of modules ... failed" warning messages will appear across the subsequent reboots after the installation of PowerPath.   
   
     
                                                           

 

 

Resolution:

 

 

These error messages and warnings are safe to ignore and PowerPath Engineering is in discussion with Oracle for a resolution. these errors are documented in the Readme file which normally comes with PowerPath 6.0 P03 HF 01 for Solaris (also attached to this KB)
