A-22 Using PPRC Commands for TrueCopy for z/OS
Hitachi Universal Storage Platform V TrueCopy for IBM z/OS User’s Guide
CRECOVER
Table A-10 describes how to use the CRECOVER command to release TCzA
pairs and groups at the RCU. The syntax for the CRECOVER command is:
For 3990-6 and -6E controller emulations:
CRECOVE
R
DEVN(X’dev#’) PRIM(X’ssid’ cmd_param X’cca’) SEC(X’ssid’
serial# X’cca’)
[ID(
old_volser[new_volser])]
For 2105 and 2107 controller emulation (new ‘lss’ parameter for LCU number):
CRECOVE
R
DEVN(X’dev#’) PRIM(X’ssid’ serial# X’cca’ X’lss’) SEC(X’ssid’
cmd_param X’cca’ X’lss’)
[ID(
old_volser[new_volser])]
Table A-10 Using CRECOVER to Release TrueCopy for z/OS Async
Pairs/Groups at the RCU
Parameters Contents Description
AC000
Specifies that all pairs (R-VOLs) in the consistency group whose
consistency status is Suspended-Group should be released.
AG000
Specifies that all pairs (R-VOLs) in the consistency group should be
released regardless of pair status and consistency status. All pending
recordsets will be settled before releasing the pairs.
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.
AV000
Specifies that the addressed pair (R-VOL) should be released
regardless of pair status and consistency status. All pending recordsets
for the addressed pair will be settled before releasing the pair.
[ID(old_volser[new_volser])]
TCzA does not support this keyword. Depending on the timing, the
write command to change the volume serial number may be rejected.
Notes:
• The addressed device must be the R-VOL.
• If the first digit of the cmd_param is other than A, the storage system
interprets this command as pair release for TCz Synchronous or
ShadowImage for z/OS.
• Regardless of the number of pairs to be released, this command ends before
the actual pair release is successfully completed. Confirmation by CQUERY or
IEA494I console message is recommended after this command.
