Updating the Target Mirroring Configuration
Changes the target's mirroring configuration.
target_config_sync_rates target=TargetName
[ max_initialization_rate=MaxInitializationRate ]
[ max_syncjob_rate=MaxSyncjobRate ] [ max_resync_rate=MaxResyncRate ]
Parameters:
Name Type Description Mandatory Default
target Object name The updated
target.
Y N/A
max_
initializa
tion_rate
Positive integer Specifies the
maximum rate for
initial
synchronization.
Cannot be larger
than
max_syncjob_rate.
N Unchanged
max_
syncjob_
rate
Positive integer Specifies the
default maximum
rate for sync job
synchronization.
Cannot be larger
than
max_resync_rate.
N Unchanged
max_
resync_
rate
Positive integer Specifies the
maximum rate for
re-synchronization
N Unchanged
This command changes the system ID of the remote target. The synchronization
rate units are Megabytes per second. The default rates are: 100 MB/s for
initialization rate, 300 MB/s for resync rate. The default system_id is the value that
is set with the config_set command.
Access Control:

Storage integration administrator Allowed
Application administrator Disallowed
Security administrator Disallowed
Read-only users Disallowed
Technicians Disallowed
Completion Codes:
v TARGET_BAD_NAME
Target name does not exist
v TARGET_ILLEGAL_RATE_VALUES
max init rate should be smaller or equal to max sync job rate. max sync job rate
should not be greater than max resync rate.
