APAR status

  • Closed as program error.

Error description

  • XIV hdisk attributes (like algorithm, reserve_policy and
    queue_depth) are changing from custom values back to
    defaults
    (round_robin, no_reserve and 1) after reboot.
    This defect is not limited to XIV only.
    

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 on reboot.
    

Problem conclusion

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

Temporary fix
