• When cmd_param AGxxx is specified, this command ends before the actual pair
establishment/re-establishment successfully starts. Confirmation by CQUERY or IEA494I console
message is recommended after this command.
CSUSPEND
Table 40 on page 167 describes how to use the CSUSPEND command to suspend TC390A pairs and
groups. The syntax for the CSUSPEND command is:
For 3990-3, -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’
cmd_param X’cca’ X’lss’) SEC(X’ssid’ serial# X’cca’ X’lss’)
[PRIMARY] [QUIESCE]
NOTE: If you need write access to an R-VOL, you must delete the pair (CDELPAIR).
*If the addressed device is the M-VOL, only TC390A pairs in the same disk array are suspended. 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
suspension for TC390 Synchronous or SI390.
• The D and P in
cmd_param stand for the Drain and Purge options, respectively. For a detailed
description of these TC390A suspend options, see ”Suspending TrueCopy pairs (Suspend Pair)” on
page 131.
• When P (Purge) is specified, it is not possible to determine exactly which recordset will be settled
before the addressed volume pair is suspended.
• 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:
Table 40 Using CSUSPEND to suspend TrueCopy Async pairs
Parameters Contents Description
cmd_param AGD00 Specifies that all the volume pairs in the consistency group should be suspended
after all pending recordsets are settled (Drain suspend option).
AGP00 Specifies that all the volume pairs in the consistency group should be suspended.
Pending recordsets are not always settled before suspension (Purge suspend
option).
AVD00 Specifies that only addressed volume pair should be suspended after the pending
recordset for addressed volume settled (Drain suspend option).
AVP00 Specifies that only the addressed volume pair should be suspended. Pending
recordsets for addressed volume are not always settled (Purge suspend option).
PRIMARY Invalid keyword for TC390A volume pairs.
QUIESCE Invalid keyword for TC390A volume pairs.
