Draft Document for Review February 7, 2020 3:15 pm 8464ch14_DisasterRecoveryTesting.fm This status results if an unexpected error occurs internally and the current active  asynchronous operation status cannot be checked. If this error occurs, contact IBM  hardware support. If this command is received by a cluster in the grid that is running R5.0 or above and too many  write protect exclusion categories exist to be shown within 50 lines of whole output, the  following message is shown at the end of the write protect exclusion categories list: MORE WRITE PROTECT EXCLUDED CATEGORIES TO DISPLAY EXIST 14.4.4 LIVECOPY enablement in a DR Family A DR Family must contain at least one TS7700. If a TS7700T or TS7700C is present within a  DR Family, an option is available allowing the “live” copy on the TS7700T or TS7700C cluster  to be accessed if it is a completed replication or was otherwise consistent within the TS7700T  or TS7700C before Time Zero of the DR test. This option is applicable if the TS7700 removed  its copy or if the TS7700T or TS7700C was the only target of the volume. This option is called  LIVECOPY . LIVECOPY  allows read access from a DR host to production volumes that were consistent  before time zero of a FlashCopy and do not exist in cache on the FLASHed TS7700 but do  exist on a physical backend tape or object cloud store that is attached to a TS7700. If a  volume in this state is accessed from a DR host and  LIVECOPY  is enabled, the mount is  satisfied. If a volume is in this state and  LIVECOPY  is NOT enabled, the mount fails.  The option is disabled by default. If you choose to enable this function, you must specifically  enable the option by using the  Library Request  command with  LIVECOPY  keyword: (see  Example 14-3): LI REQ,<clib_name>,DRSETUP,<family_name>,LIVECOPY,FAMILY Example 14-3 Enable the LIVECOPY option To disable the LIVECOPY option, you must run the following command (see Example 14-4):  LI REQ, <clib_name>, DRSETUP, <family_name>, LIVECOPY, NONE Example 14-4 Disable the LIVECOPY option LI REQ,HYDRAG,DRSETUP,DRFAM01,LIVECOPY,NONE  CBR1020I Processing LIBRARY command: REQ,HYDRAG,DRSETUP,DRFAM01,LIVECOPY NONE.
