152 TrueCopy for the XP128/XP1024/XP10000/XP12000
CESTPAIR DEVN(X’dev#’) PRIM(X’ssid’ cmd_param X’cca’ X’lss’) SEC(X’ssid’ serial# X’cca’ X’lss’)
[MODE(COPY|NOCOPY|RESYNC)] [PACE(pace)] [CRIT(YES|NO)] [MSGREQ(YES|NO)]
• If the first digit of the cmd_param is other than
A
, the disk array interprets this command as pair
establishment for TC390 Synchronous or SI390.
• The consistency group nn must be registered prior to this command. Otherwise this command will be
rejected.
• When
MODE(RESYNC)
is specified, the consistency group number n must be the consistency group
number to which the addressed device belongs. If a different number is specified, this command will be
rejected.
• When
MODE(RESYNC)
is specified, the copy mode (synchronous or asynchronous) cannot be
changed. If a different copy mode is specified, this command will be rejected.
• If the consistency group requirements (see ” Consistency Groups ” on page 47) are not satisfied, this
command may/may not be rejected.
• The delay option prevents command retry delay for this pair when sidefile is above the HWM (see
” Graduated Delay Sidefile Management” on page 33 ). If not specified correctly, command is rejected
(F/M=04).
Table 34 Using CESTPAIR to establish and resume TrueCopy Async pairs
Parameter Contents Description
cmd_param AGnnd
nn = consistency group
number (00-7F) or master
volume number (00-FF: for
dummy pair mode).
d = 0, N, or D
Without MODE(RESYNC): Specifies the consistency group number
nn to which the volume pair will belong.
With MODE(RESYNC): Specifies that all M-VOLs in the consistency
group should be resynchronized (resumed).
nn must specify the consistency group number of the addressed
device or the master volume number. For dummy pair mode, nn
must specify the master volume number.
d specifies the delay option for command retry due to sidefile:
0 = normal delay for command retry starting at HWM (see
” Graduated Delay Sidefile Management” on page 33 )
N = no delay time: no command retry delay due to sidefile for
this pair. Use the N setting only for a limited number of critical
volumes.
D = dummy pair mode (nn must specify the master volume
number).
AVnnd
nn = consistency group
number (00-7F) or master
volume number (00-FF: for
dummy pair mode).
d
= 0, N, or D
With MODE(RESYNC): Specifies that only the addressed device
should be re-synchronized.
nn must specify the consistency group number of the addressed
device or the master volume number. For dummy pair mode, nn
must specify the master volume number.
d
specifies the delay option for command retry due to sidefile:
0 = normal delay for command retry starting at HWM (see
” Graduated Delay Sidefile Management” on page 33 )
N = no delay time: no command retry delay due to sidefile for
this pair. Use the N setting only for a limited number of critical
volumes.
D = dummy pair mode (nn must specify the master volume
number).
PACE (pace) Specifies the pace of the initial copy operation: 1-255, default=15
tracks.
CRIT (YES) Specifies the Error Level (TC390A pair option) of Group.
(NO) Specifies the Error Level (TC390A pair option) of Volume.
