Required parameters

DEVN

Specifies the device number of any disk volume that is attached to the primary site storage control without directing any operation to the volume. The device number is the 4-digit hexadecimal address of any disk volume behind the primary site storage control.

When issuing this command for an open device LSS, DEVN specifies a System z® device located in the same subsystem cluster as the primary device.

PRIM

Specifies the primary site storage subsystem ID (SSID), serial number (serialno), and logical storage subsystem (LSS).

Where:

ssid: Specifies a 4-character hexadecimal subsystem identifier (SSID). ssid must be specified in X'' notation.
serialno: Specifies the storage subsystem serial number, which can include up to 12 digits, depending on the type of logical subsystem. Using a serial number indicates the LINK addresses are for ESCON® channel interfaces. If the serial number is supplied for the primary logical subsystem, the serial number must also be supplied for the secondary logical subsystem.
lss: Specifies a 2-digit hexadecimal value that identifies the logical subsystem for the device.

Note: LSS number is required if the storage control supports logical subsystems (like the ESS) and not allowed if the storage control does not support logical subsystems.

SEC

Specifies the recovery site storage subsystem ID and serial number. The description for the values is the same as for the PRIM parameter.
