TrueCopy for z/OS user guide 163
• Regardless of the number of volume pairs to be suspended, this command ends before the actual pair
suspension is successfully completed. Confirmation by CQUERY or IEA494I console message is
recommended after this command.
CDELPAIR
The following table describes how to use the CDELPAIR command to delete TC390A pairs and groups at
the MCU. The syntax for the CDELPAIR command is:
For 3990-3, -6 and -6E controller emulations:
CDELPAIR DEVN(X’dev#’) PRIM(X’ssid’
cmd_param X’cca’ X’lss’) SEC(X’ssid’ serial# X’cca’ X’lss’)
For 2105 controller emulation (new ‘lss’ parameter for LCU number):
CDELPAIR DEVN(X’dev#’) PRIM(X’ssid’
cmd_param X’cca’ X’lss’) SEC(X’ssid’ serial# X’cca’ X’lss’)
*Only TC390A pairs in the same disk array are deleted. Volume pairs whose M-VOLs are behind other
MCUs are not affected.
• If the first digit of the
cmd_param is other than A, the disk array interprets this command as pair
deletion for TC390 Synchronous or SI390.
• The specified pair(s) will be deleted regardless of their pair status. After the pair(s) is/are deleted, the
volume(s) will not indicate their pair status before pair deletion. To delete TC390A pairs with their
update sequence consistency ensured:
• Issue the CSUSPEND command with
cmd_param of AGP00 or AGD00.
• Issue CQUERY to confirm that the specified pairs have been successfully suspended with the
consistency status of Group.
• Issue the CDELPAIR command.
• Regardless of the number of volume pairs to be deleted, this command ends before the actual pair
deletion is successfully completed. Confirmation by CQUERY or IEA494I console message is
recommended after this command.
CRECOVER
The following table describes how to use the CRECOVER command to delete TC390A pairs and groups at
the RCU. The syntax for the CRECOVER command is:
For 3990-3, -6 and -6E controller emulations:
CRECOVER DEVN(X’dev#’) PRIM(X’ssid’
cmd_param X’cca’) SEC(X’ssid’ serial# X’cca’
[ID(
old_volser[new_volser])]
For 2105 controller emulation (new ‘lss’ parameter for LCU number):
Table 41 Using CDELPAIR to delete TrueCopy Async pairs/groups at the MCU
Parameters Contents Description
cmd_param AG000 Specifies that all pairs in the consistency group* should be deleted. All pending
recordsets will be settled before deleting the volume pairs.
AV000 Specifies that only the addressed pair should be deleted. All pending recordsets
for the addressed volume will be settled before deleting the volume pair.
