Resynchronizing Pairs Using Pprc Commands; Cestpair (Resynchronizing Pairs) - HP StorageWorks XP24000 User Manual

1 If you perform a quick split request on all pairs in a CTG, confirm that the status of all pairs in the group is DUPLEX. If
there are one more pairs whose statuses are PENDING in the group, the quick split operation sometimes ends abnormally
(CC = 12). If this occurs, wait until the copy operation for that pair ends.
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).
3 The CSUSPEND QUIESCE option has been disabled by APAR OW15247 or APAR OW15248. See either of these
APARs and the latest IBM PPRC documentation for detailed information about the QUIESCE option. Check with your
HP 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.
4 CU number or the parameter is valid only for the DKC emulation type 2105 or 2107.

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.

Device number.
Primary volume (S-VOL): SSID, serial number,
channel connection address, and CU number.
You can set an additional parameter
corresponding to each request instead of a
serial number.
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.

If you set a parameter other than the
parameters on the left, the command will be
rejected.
