See *Note 3 of Table 7-6. However, please refer

to the IBM document for important information.

LSS Primary volume CU number, and

secondary volume CU number

*Note 1: CU number or the parameter is valid only for the DKC emulation

type 2105 or 2107.

*Note 2: The parameter is valid only for the DKC emulation type 3390. If the

DKC emulation type is 2105 or 2107, the TSO command ignores the

parameter and the ICKDSF job ends abnormally (CC = 12).

Figure 7-5 shows an example of the PPRCOPY SUSPEND command.

Resynchronizing Pairs Using PPRC Commands

The CESTPAIR and PPRCOPY ESTPAIR commands is equivalent to the

ShadowImage for z/OS normal resync operation. The CESTPAIR and PPRCOPY

ESTPAIR commands must be issued to the S-VOL, and the pair status must be

split or suspend when you resynchronize pairs.

CESTPAIR (Resynchronizing Pairs)

Table 7-8 lists and describes the CESTPAIR command parameters that can be

used when you resynchronize SIz pairs.
