Splitting Pairs: CSUSPEND QUIESCE Parameter
See the following document for important information on the optional QUIESCE parameter for the
CSUSPEND TSO command, HP StorageWorks XP24000/XP20000 for Compatible Extended Remote
Copy (XRC) Software User’s Guide.
WARNING!
The CSUSPEND QUIESCE option has been disabled by APAR OW15247 or APAR OW15248. Refer
to either of these APARs and the latest PPRC documentation for detailed information on the QUIESCE
option. Check with your HP account team before using the QUIESCE option with the storage system. If
the QUIESCE option is issued to certain volumes (e.g., active SPOOL, PAGE, or CATALOG datasets,
active SYSRES volume), the attached host(s) may enter a deadlock condition and may require a storage
control IML to correct the condition.
The QUIESCE parameter is used to modify the functionality of the CSUSPEND TSO command. For
example, if the QUIESCE parameter is specified, the pair is quiesced and subsequent write requests to the
S-VOL are suspended by the host until the QUIESCE condition is released.
You can use QUIESCE parameter to the Siz pairs only when the pair status is duplex. If a Siz S-VOL
has more than one T-VOL, the QUIESCE parameter is effective if at least one pair is specified. Write
requests at the S-VOL start when all QUIESCE conditions are released. The following conditions cause
the storage system to automatically release the QUIESCE condition:
• A CSUSPEND TSO command without the QUIESCE parameter is accepted.
• A CDELPAIR TSO command is accepted.
• A Delete, Suspend, or Split Pair command (from the Remote Web Console) is accepted.
• Storage system power-on-reset is executed.
NOTE:
If a Siz pair is suspended because of an internal Storage System error condition, the QUIESCE option is
applied. In this case, release the QUIESCE condition by deleting the pair.
Siz and TCz are processed independently. The CSUSPEND/QUIESCE command is effective for either
the Siz or TCz pair specified in the command.
Re-synchronizing Pairs: MODE(RESYNC) Parameter
The MODE(RESYNC) option of the CESTPAIR and PPRCOPY ESTPAIR commands is equivalent to the Siz
normal resync operation (changes pair status to resync). The CESTPAIR and PPRCOPY ESTPAIR commands
must be issued to the S VOL, and the pair status must be split or suspend when MODE(RESYNC)
is specified.
The following is an example of the CESTPAIR command with the MODE(RESYNC) parameter.
CESTPAIR DEVN (X ‘DE80’ ) PRIM (X ‘0080’ ,30158,X ‘00’ ) SEC (X ‘0080’ ,30158,X ‘01’ )
MODE (RESYNC) PACE (15)
The following is an example of the PPRCOPY ESTPAIR command with the MODE(RESYNC) parameter.
