account representative before using the QUIESCE option with the HP XP disk array storage system. If the QUIESCE option
is issued to certain volumes (for example, active SPOOL, PAGE, or CATALOG datasets, active SYSRES volume), the
attached hosts may enter a deadlock condition and may require a storage control IML to correct the condition.

Resynchronizing Pairs Using PPRC Commands
The CESTPAIR and PPRCOPY ESTPAIR commands is equivalent to the ShadowImage for Mainframe
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 41 (page 97) lists and describes the CESTPAIR command parameters that can be used when
you resynchronize SIz pairs.
Table 41 CESTPAIR Command Parameters (Resynchronizing Pairs)
Description Value Parameter
Device number. DEVN
If you set a parameter other than the
parameters on the left, the command will be
rejected. Primary volume (S-VOL): SSID, serial number,
channel connection address, and CU number.
1
You can set an additional parameter
corresponding to each request instead of a
serial number.
PRIM
For a Quick Resync request, set MRF00. This
parameter is valid for MODE(RESYNC) only.
For a Quick Restore request, set MRQ00. This
parameter is valid for MODE(RESYNC) only.
For a Reverse Copy request, set MRR00. This
parameter is valid for MODE(RESYNC) only.
For a Resync request on all pairs in a CTG, set
MAnn0. where nn is the CTG ID. This request
triggers a normal Resync operation.
Secondary volume (T-VOL): SSID, serial
number, channel connection address, and CU
number.
1
SEC
Re-establish a split or suspended volume pair.
This parameter is required. RESYNC MODE
Copy speed of resynchronization will be slow,
except when the DKC emulation type is 2105 1 PACE
or 2107. When the DKC emulation type is
2105 or 2107, the copy speed of
resynchronization is always medium regardless
what you specify for the PACE parameter.
