Received an IWNR2108E error

Edit online

This condition occurs during normal operation of a FlashCopy® session on the ESS/DSDS8000.

Problem

During an ESS/DSDS8000 practice session, the Flash command fails with the following hardware errors:
IWNR2108E:  A hardware error occurred while issuing the
command for the pair in session mmprac for copy set [copy_set
] with source
[source] and target [target]. The hardware returned an error code of 0f60
or 0f65. 

x0F60: The secondary volume for an establish PPRC pair command or the target
volume for an establish FlashCopy command is in a grouped state which 
implies the volume is online with a host.

x0F65: The Establish PPRC Pair command or the Establish FlashCopy command
could not complete. A target Fixed Block LUN cannot be reserved to another
initiator.

The Flash command fails if the H2 volume has a host reservation on it. The reservation must be removed from the volume before the Flash command can complete successfully.

Action

Remove the reservation from the host server that is attached to the volume and issue the Flash command again to copy the data to the H2 volumes. For a FlashCopy session, copy the data to the T1 volume.
