Table 65 Using CDELPAIR to Release TrueCopy for Mainframe Async Pairs/Groups at the MCU
DescriptionContentsParameter
Specifies that all pairs in the consistency
group* should be released. All pending
AG000 cmd_param
1
recordsets will be settled before releasing the
pairs.
Specifies that only the addressed pair should
be released. All pending recordsets for the
AV000
addressed volume will be settled before
releasing the pair.
NOTE:
• If the first digit of the cmd_param is other than A, the storage system interprets this command
as pair release for TrueCopy for Mainframe Synchronous or ShadowImage for Mainframe.
• The specified pair(s) will be released regardless of their pair status. Once the pair(s) is/are
released, the volume(s) will not indicate their pair status before pair release. To release
TrueCopy for Mainframe Asynchronous 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 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.
CRECOVER
“Using CRECOVER to Release TrueCopy for Mainframe Async Pairs/Groups at the RCU” (page 201)
describes how to use the CRECOVER command to release TrueCopy for Mainframe Asynchronous
pairs and groups at the RCU. The syntax for the CRECOVER command is:
For 3990-6 and -6E controller emulations:
CRECOVER
DEVN(X'dev#') PRIM(X'ssid' cmd_param X'cca') SEC(X'ssid' serial#
X'cca')
For 2105 and 2107 controller emulation (new lss parameter for LCU number):
CRECOVER
DEVN(X'dev#') PRIM(X'ssid' serial# X'cca' X'lss') SEC(X'ssid'
cmd_param X'cca' X'lss')
