Using PPRC Commands for TrueCopy for z/OS A-19
Hitachi Universal Storage Platform V TrueCopy for IBM z/OS User’s Guide
CSUSPEND
Table A-8 describes how to use the CSUSPEND command to suspend TCzA
pairs and groups. The syntax for the CSUSPEND command is:
For 3990-6 and -6E controller emulations:
CSUSPEND
DEVN(X’dev#’) PRIM(X’ssid’ cmd_param X’cca’) SEC(X’ssid’ serial# X’cca’)
[PRIMARY]
[QUIESCE]
For 2105 and 2107 controller emulation, addressed device is M-VOL (new ‘lss’
parameter for LCU no.):
CSUSPEND
DEVN(X’dev#’) PRIM(X’ssid’ cmd_param X’cca’ X’lss’) SEC(X’ssid’ serial#
X’cca’ X’lss’)
[PRIMARY]
[QUIESCE]
For 2105 and 2107 controller emulation, addressed device is R-VOL (new ‘lss’
parameter for LCU no.):
CSUSPEND
DEVN(X’dev#’) PRIM(X’ssid’ X’cca’ X’lss’) SEC(X’ssid’ cmd_param serial#
X’cca’ X’lss’)
[PRIMARY]
[QUIESCE]
Note: If you need write access to an R-VOL, you must release the pair
(CDELPAIR).
Table A-8 Using CSUSPEND to Suspend TrueCopy for z/OS Async Pairs
Parameters Contents Description
AGD00
Specifies that all the pairs in the consistency group should be suspended after all
pending recordsets are settled (Drain suspend option).
AGP00
Specifies that all the pairs in the consistency group should be suspended. Pending
recordsets are not always settled before suspension (Purge suspend option).
AVD00
Specifies that only addressed pair should be suspended after the pending
recordset for addressed volume settled (Drain suspend option).
cmd_param
Note: This parameter
is for TCz Async only.
For Sync replace
cmd_param with the
serial number of the
primary or secondary
storage system.
AVP00
Specifies that only the addressed pair should be suspended. Pending recordsets
for addressed volume are not always settled (Purge suspend option).
PRIMARY Invalid keyword for TCz Asynchronous pairs.
QUIESCE Invalid keyword for TCz Asynchronous pairs.
* If the addressed device is the M-VOL, only TCzA pairs in the same storage system are suspended. Pairs whose M-VOLs
are behind other MCUs are not affected.
