Cause:

 

 

PowerPath for Linux 7.0 bug.                                                           

 

 

Change:

 

 

Installation or upgrade to PowerPath for Linux 7.0.                                                           

 

 

Resolution:

 

 

For RHEL 7.x and RHEL 8.x this is fixed in PowerPath for Linux 7.0 P01 and later releases.   
    PowerPath for Linux 7.0 P01 is available for download at the support site.
                                                           

 

 

Notes:

 

 

This fix is only applicable for RHEL 7.x and RHEL 8.x.   
    This bug is specific to PowerPath for Linux 7.0 Only.   
    This bug is limited to the LUN nice name and is cosmetic in nature.    
    There is no impact to other PowerPath functionality such as path failover and I/O load balancing.   
   
    For other Linux OS distributions this fix is scheduled to be released in the next major release of PowerPath for Linux.
