Parameters

The following transactions must be completed before you can issue the commitflash command:

Issue the mkflash command with the -record and -persist parameters specified to establish the FlashCopy volume pair relationship.
Issue the setflashrevertible command on the FlashCopy volume pair.

-dev storage_image_ID: (Optional) Specifies the storage image ID, which includes manufacturer, machine type, and serial number. This parameter is required if you do not specify a fully qualified ID for all the source volumes and you do not specify a value for the devid variable in your profile file.; Example: IBM.1750-68FA120
-seqnum flash_sequence_number: (Optional) When a FlashCopy sequence number is specified, the commit operation is performed only on those relationships that are associated with the specified number.; This parameter is not supported for machine type 2105.; Example: 0010
source_volume_ID . . . | –: (Required) Specifies the source volumes for which FlashCopy relationships are to be committed. The chosen FlashCopy pair is the one established or modified with the -record parameter. This parameter accepts fully qualified volume IDs, which includes storage image IDs, or a shortened version without storage image IDs if either the -dev parameter is specified or you specify a value for the devid variable in your profile file. You must separate multiple source volume IDs with spaces.; 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 volume ID: IBM.1750-68FA120/0001; Example of a shortened version: 0001; Example of multiple IDs: 0001 0003 0008
