Setting Up Remote Copy
Remote Copy User’s Guide InForm OS Version 2.3.1
The creatercopygroup command creates a volume group on the primary storage server
(InServ1). At the same time, it also creates a corresponding secondary group
(Group1.r112) on the target system (InServ2). The corresponding secondary group uses
the naming convention
<primary_group_name>.r<sys_ID>.
2 (Optional). If you chose
periodic mode in step 1, you might want to set up automatic
synchronization by specifying a resynchronization period as follows. Do not set a
resynchronization period if you plan to perform the initial synchronization using a tape
backup, as described on page 3.38.
◆ <value> is the resynchronization period, followed by s to denote seconds, m to
denote minutes,
h to denote hours, or d to denote days.
◆ <target_name> is the target name (InServ2).
◆ <group_name> is the name of the primary volume group (Group1).
NOTE: For N-to-1 configurations, only asynchronous periodic mode volume
groups are supported.
NOTE: When issuing commands that are mirrored from one system to another,
there is a five minute timeout limit. After five minutes, if the other system does
not respond to a command, the following error message appears:
target system <sys_name> could not be contacted
NOTE: You can create groups and add volumes to groups without disrupting host
access to volumes. In addition, stopping a Remote Copy volume group does not
prevent a host from accessing the volumes in that group.
On InServ1:
# setrcopygroup period <value> <target_name> <group_name>
