setflashrevertible

The setflashrevertible command modifies a FlashCopy volume pair that is part of a Global Mirror relationship to revertible. The revertible feature allows data to be committed to the target to form a new consistency, or reverted back to the last consistency. This command must be run before the FlashCopy pair can be committed or reverted.

Parameters

Note: The -nocp, -record, -persist, and -tgtinhibit (target inhibit) parameters are included automatically when this command processes.

-dev storage_image_ID: (Optional) Specifies the storage image ID, which includes manufacturer, type, and serial number. This parameter is required if you do not specify a fully qualified ID for the source volume and you do not specify a value for the devid variable in your profile file.; Example: IBM.1750-68FA120
-tgtoffline: (Optional) Causes an establish FlashCopy volume pair command to be rejected if the target volume is online for host system access. This parameter applies only to CKD volumes.
-seqnum flash_sequence_num: (Optional) Associates the FlashCopy relationships that are changed with the specified sequence number. Only the relationships that are successfully modified by the command are assigned the specified sequence number, leaving the ones that fail with the previous number (if previously specified).; This parameter is not supported for machine type 2105.; Example: 0010
source_volume_ID:target_volume_ID . . . | -: (Required) Modifies FlashCopy relationships for the source and target volume pairs with the IDs specified. This parameter accepts fully qualified volume IDs, which includes storage image IDs, or a shortened version without storage image IDs if the -dev parameter is specified, or you can specify a value for the devid variable in your profile file. You must separate multiple FlashCopy pair IDs with spaces.; A FlashCopy pair ID consists of two volume IDs, one designated as the source and the other as the target volume for a FlashCopy relationship. You must separate the two volume IDs of a FlashCopy pair ID with a colon and no space. The first volume ID is the source volume. The second volume ID is the target volume.; The volume ID is a 32 bit number that can be represented as 4 hexadecimal digits in the form of XYZZ where X is the address group (0 - 1), XY together is the logical subsystem number 00 - 1E (for 1750) , and ZZ is the volume number (00 - FF).; If you specify the dash (-), this parameter information is automatically supplied.; Example of a fully qualified FlashCopy pair ID: IBM.1750-68FA120/0001:IBM.1750-68FA120/0004; Example of a shortened version: 0001:0004; Example of multiple pairs: 0001:0004 0003:00FF 0008:000C
