1. Create a volume group on the primary system (SystemA):
# creatercopygroup :sync :periodic
where:
•
—Name of the volume group (testgroup).
•
—Name of the target systems (SystemB and SystemC).
•
sync | periodic —sync for synchronous mode and periodic for asynchronous
periodic mode. SLD configurations require one target system to be in sync mode and the
other target system to be in asynchronous periodic mode.
For example:
# creatercopygroup testgroup SystemB:sync SystemC:periodic
The creatercopygroup command creates the following:
•
A primary volume group (testgroup) on the primary system (SystemA).
•
A name for the secondary volume groups using the following convention:
.r (of the primary system)
In this example, the secondary volume groups are both named testgroup.r96.
•
The secondary volume group (testgroup.r96) on each target system (in this case, on
backup systems SystemB and SystemC).
Solution Problem
Ensure that links are up on both systems and try the
command again. For more information, see
“Checking
the Links between Systems for SLD Remote Copy”
(page 64)
.
If the backup system does not respond to a command
after 5 minutes (the timeout limit), an error message
appears:
target system could not be
contacted
