revertremoteflash

The revertremoteflash command is used to restore data on the source volume to its most recent consistency formation. All new write operations to the source since the most recent consistency formation are overwritten with the previous consistency.

Parameters

You must take the following actions before you can use the revertremoteflash command:

Notes:

Issue the mkflash or mkremoteflash command with the -persist and -record parameters to establish the FlashCopy pair.
Issue the setflashrevertible or setremoteflashrevertible command against the FlashCopy pair.

-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 or you do not specify a value for the devid variable in your profile file.
-conduit LSS_ID: (Required) Specifies the source logical subsystem (LSS) of an existing remote mirror and copy (formerly PPRC) relationship that is used as a means for communicating with the remote storage image. The source volume IDs that are specified in SourceVolumeID:TargetVolumeID must serve as secondary volumes in a remote mirror and copy relationship in which one of the conduit LSS volumes serves as a primary volume.; When you use this parameter, you must specify a full qualified LSS ID. The fully qualified LSS ID format is storage_image_ID/XX, where XX is a hexadecimal number in the range00 - 1F (1750 only).; Example: IBM.2107-75FA120/00; Example: IBM.1750-68FA120/00
-seqnum flash_sequence_num: (Optional) When a FlashCopy sequence number is specified, the revertremoteflash operation is performed only on those relationships that are associated with the specified number.; Example: 0010; This parameter is not supported for machine type 2105.
-srcss SS_ID: (Optional) Specifies the subsystem ID of the source logical subsystem at the remote site. The ID is in the format 0x0001 - 0xFFFF.; This value is required for the IBM System Storage™ Enterprise Storage Server versions 2.4.0 and 2.4.1. 3. When you specify SS_IDs, the source volumes are restricted to one logical subsystem.; Example: FF10
SourceVolumeID . . . | -: (Required) Specifies the remote FlashCopy relationship for the source volume with the specified ID that is to be reverted. The chosen FlashCopy pair is the one that is 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 the -dev parameter is specified. 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 shortened version: 0001; Example of multiple IDs: 0001 0003 0008

Example (1750)
