The mkpprcpath command
establishes or replaces a remote mirror and copy (formerly PPRC) path between
source and target logical subsystems (LSSs) over a fibre-channel connection.
This is the only supported connectivity for machine types 2107 and 1750. Paths
can be established between the following machine types: 2105:2105, 2107:2107,
2107:1750, 2107:2105, 1750:1750, 1750:2105.

Parameters
- -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 port ID.
- -remotedev storage_image_ID
- (Optional) Specifies the ID of the secondary storage image, which
includes manufacturer, machine type, and serial number. If specified, the
format of this entry might be checked for correctness although the value is
not used
- Example: IBM.1750-68FA150
- -remotewwnn wwnn
- (Required) Specifies the worldwide node name of the secondary storage
image. The format is a 16-hexadecimal ID.
Note: Ensure that you use the worldwide node name
that is associated with the secondary storage unit. Run the lssi or showsi command
to obtain this number.
- Example: 12341234000A000F
- -srclss source_LSS_ID
- (Required) Specifies the source logical subsystem ID. Use a fully qualified
LSS ID, which includes the storage image ID, or use a shortened version without
the storage image ID, if the -dev parameter is used.
The fully qualified LSS ID format is storage_image_ID/XX, where XX is
a hexadecimal number in the range (1750) 00 - 1F.
- Example of a shortened version: 00
- -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 TotalStorage Enterprise Storage Server
versions 2.4.0 and 2.4.1.
- Example: 0010
- -tgtlss target_LSS_ID
- (Required) Specifies the logical subsystem ID associated with the secondary
storage unit as the target. Use a fully qualified LSS ID, which includes the
storage image ID. The fully qualified LSS ID format is storage_image_ID/XX,
where XX is a hexadecimal number in the range (1750) 00 - 1F.
- Example of a shortened version: 01
- -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 TotalStorage Enterprise Storage Server
versions 2.4.0 and 2.4.1.
- Example: 0010
- -consistgrp
- (Optional) Creates a consistency group for the remote mirror and copy
volume pairs. A remote mirror and copy consistency group is a set of remote
mirror and copy volume pairs that have the same source and target LSS.
- Normally, when an error occurs in a member of a remote mirror and copy
volume pair, the storage unit places the volume in a suspended state.
However, if the volume participates in a consistency group, it is placed in
a long busy state.
- source_port_ID:target_port_ID . . . | -
- (Required) Establishes a remote mirror and copy path between the source
and target ports for the specified source and target logical subsystems.
The source and target ports must be fibre-channel I/O ports that are configured
for point-to-point or switched fabric topology. They are enabled automatically
for remote mirror and copy secondary I/O operations. They are not enabled
for FICON I/O operations.
- Use fully qualified port IDs, which includes the storage image ID, or
use a shortened version without the storage image ID if the -dev parameter
is specified. A remote mirror and copy path port pair ID consists of two port
IDs. Designate the first as the source port and the second as the target port
for the remote mirror and copy path. You must separate the two port IDs with
a colon and no spaces. A port ID is four hexadecimal characters in the format EEAP,
where EE is a port enclosure number (00 - 3F), A is the adapter
number (0 - F), and P is the port number (0 - F). This number is prefixed
with the letter I.
- This parameter accepts up to eight remote mirror and copy path port pair
IDs. You must separate multiple port pair IDs with spaces.
- If you specify a dash (-), this parameter information is automatically
supplied.
- Example of the shortened version: I1A10:I2A20
- Example of multiple pairs: I1A10:I2A20 I1A11:I2A21 I1A12:I2A22
Example (1750)
