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 and 2107 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 3990-6 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’)
•
The addressed device must be the R-VOL.

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.
Table 42
Using CRECOVER to delete TrueCopy Async pairs/groups at the RCU
Parameters
Contents
Description
cmd_param
AC000
AC000Specifies that all volume pairs (R-VOLs) in the consistency group whose
consistency status is Suspended-Group should be deleted.
AGP00
AG000Specifies that all volume pairs (R-VOLs) in the consistency group should
be deleted regardless of pair status and consistency status. All pending
recordsets will be settled before deleting the pairs.
AVD00
AV000Specifies that the addressed volume pair (R-VOL) should be deleted
regardless of pair status and consistency status. All pending recordsets for the
addressed pair will be settled before deleting the pair.
[ID(old_volser[new_volser])]
TC390A does not support this keyword. Depending on the timing, the write
command to change the volume serial number may be rejected.
