Hello Daz,   No there is no user option to force a mirror.  However, reconstruction of blocks on a drive is not unusual.  Notice that it is an INFO message not even a warning.  If this continues or there are no more blocks available to swap, the drive will be mirrored out.   If you are not at current firmware in your group, I would suggest you do so.   Newer firmware has many enhancements in disk handling.  For example, newer firmware support SMART drive trips.  So the drive will warn the array when a drive is failing or likely to fail.   Also there could be updated firmware available for your drives as well.   If you are still concerned, open a support case, and they can review the history of that drive for any signs of impending failure.   Regards,   Don 
I have a drive that is repeatedly reporting similar to: ----------------------------------------- INFO event from storage array RHSAN1 subsystem: SP     event: 14.2.28      time: Fri Feb 12 12:08:29 2016   13:10 I/Os containing bad blocks were read from drive 13 and successfully reconstructed in the last 73 seconds. ----------------------------------------- Is there a way please, without manual pulling the drive, that we can initiate a copy to spare rather than waiting for this drive to fail. Thanks in advance. Daz
