Required parameters

DEVN

Specifies the device number of the primary or secondary volume of the volume pair that PPRC is to suspend. The device number is the 4-digit hexadecimal address of the device to which the I/O operation is directed.

If OPENDVCS(YES) is specified, DEVN identifies a System z® device to act as a CKD access volume. This device must be located in the same subsystem cluster as the device (primary or secondary) being suspended.

PRIM

Specifies the primary site storage subsystem ID (ssid), and serial number (serialno), the primary volume channel connection address (cca), and the logical storage subsystem (lss).

Where:

ssid: Specifies a 4-character hexadecimal subsystem identifier (SSID). ssid must be specified in X'' notation. When OPENDVCS(YES) is specified, ssid can be the actual ssid, or X'FFFF' can be specified and the control unit will calculate the correct FB ssid.
serialno: Specifies the storage control serial number, which can include up to 12 digits, depending on the type of storage control.
cca: Specifies a 2-digit channel connection address. cca must be specified in X'' notation.
lun: Specifies the 2-digit logical unit number when OPENDVCS(YES) is specified. lun must be specified in X'' notation.
lss: Specifies a 2-digit hexadecimal value that specifies the logical subsystem for the device (ESS only).

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, and the secondary volume channel connection address. The descriptions for the values are the same as for the PRIM parameter.
