Error description

Local fix

  • 



Problem summary


    

  • Some disk attributes like algorithm, reserve_policy etc may
revert back to their default values upon rebooting the system.
So changes made by chdev command can be undone when on reboot.

    



Problem conclusion


    

  • Disk configuration code to be modified so that attributes are
not reverted to their default values upon reboot if they had
been changed.
