The freezepprc command creates a new remote mirror and copy consistency group.
It places the source logical subsystem (LSS) in the long busy state so that no I/Os can be directed to it. It also removes remote mirror and copy paths between the source LSS and target LSS and sets the queue full condition for the primary volume. This causes the host to queue writes to the primary volume until the queue full condition is reset. During the queue full condition, the primary volume reports long busy status.
Note: When specifying SSIDs, the command is limited to one LSS pair.
- -dev storage_image_ID
- (Optional) The source storage image ID consists of the manufacturer name, machine type, and serial number. The storage image ID is required if you do not specify a fully qualified LSS ID, do not set the devid variable in your profile or through the setenv command, and the HMC is aware of more than one storage image. Using the -dev parameter will temporarily override any defined value for devid for the current command.
- Example: IBM.2107-75FA120
- -remotedev storage_image_ID
- (Optional) The target storage image ID consists of the manufacturer name, machine type, and serial number. This parameter is required if you do not specify a fully qualified target LSS ID or if the -dev parameter is used.
- Source_LSS_ID:Target_LSS_ID ... | -
- (Required) The consistency group for the source and target LSSs with the IDs specified be placed in a long busy state. Accepts fully qualified LSS IDs, which includes the storage image ID, or a shortened version without the storage image ID if the -dev parameter is specified.
- A remote mirror and copy path LSS pair ID consists of two LSS IDs, one designated as the source LSS and the other as the target LSS for a remote mirror and copy path relationship. The two LSS IDs must be separated with a colon and no spaces. The first LSS ID is the source LSS. The second LSS ID is the target LSS.
- The fully qualified LSS ID format is storage_image_ID/xx, where xx is a hexadecimal number in the range 00 - FE.
- The ellipsis (...) indicates that, optionally, you can specify multiple values. If you use the dash (-), the specified value is read from standard input. You cannot use the dash (-) while you are in the DS CLI interactive command mode.
- Example of a pair: 00:00
- Example of multiple pairs: 00:00 01:01 02:02
