unfreezepprc

The unfreezepprc command resumes I/O activity on a storage unit where the freezepprc command has been issued. The unfreezepprc command resets the queue full condition for the primary volume. All queued writes to the source volume are written.

Parameters

Notes:

This command affects all remote copy and mirror primary volumes that are contained by the LSS(s) that are defined by the Source_LSS_ID:Target_LSS_ID source volume.
When specifying subsystem IDs, the command is limited to one LSS pair.
Resuming I/O activity on a storage unit where the freezepprc command has been issued is sometimes referred to as the thaw operation.

-dev storage_image_ID: (Optional). Specifies the source storage image ID, which includes manufacturer, machine type, and serial number. This parameter is required if you do not specify a fully qualified source LSS ID or you do not specify a value for the devid variable in your profile file.; Example: IBM.1750-68FA120
-remotedev storage_image_ID: (Optional). Specifies the target storage image ID, which includes manufacturer, 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.; Example: IBM.1750-68FA120
-srcss ss_ID: (Optional). Specifies the subsystem ID of the primary logical subsystem 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.; Example: 0010
-tgtss ss_ID: (Optional). Specifies the subsystem ID of the secondary logical subsystem 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.; Example: 0010
Source_LSS_ID:Target_LSS_ID . . . | -: (Required). Specifies that a consistency group for the source and target LSSs with the IDs specified be removed from the long busy state.; This parameter 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. Multiple remote mirror and copy path LSS pair IDs must be separated with a space between each value. 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 - 1F (1750 only).; If you specify the dash (-), this parameter information is automatically supplied.; Example pair: 00:00; Example of multiple pairs: 00:00 01:01 02:02
