A FlashCopy® Establish request detected that a specified device is in a FlashCopy relationship, or the internal ESS subsystem processing detected insufficient resources to complete the Establish of the FlashCopy relationship.
This message can also be issued if one or both of the specified devices specified in a FlashCopy Version 2 Establish request are in an active FlashCopy Version 1 relationship.
The command is rejected.
The possible causes of this error are that one or both of the devices specified in a FlashCopy Version 2 Establish request are in an active FlashCopy Version 1 relationship, or that another FlashCopy Establish for one or both of the specified devices completed just before this FlashCopy Establish was requested. Use the FCQUERY request to determine the status of the requested devices. If the devices are not in a FlashCopy relationship, this FlashCopy Establish request can be retried at a later time, when ESS resources can be available.
