Setting Up Remote Copy
InForm OS Version 2.3.1 Remote Copy User’s Guide
In order to use this command, you must specify a <group_name> (for example, Group2),
the
<target_name> (for example, InServ1) and a mode (sync for synchronous or
periodic for asynchronous periodic).
The creatercopygroup command creates a primary volume group on the primary
storage server, the storage server on which the command is issued (in this case, InServ2).
At the same time, it also creates a corresponding secondary group (Group2.r125) on the
target system (InServ1). 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 tape
backup, as described beginning on page 3.38.
where
<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 (InServ1), and <group_name> is the name of the primary volume group on
InServ2 (Group2).
3 On InServ2, add pre-existing virtual volumes to the newly created primary volume group
(Group2) as follows:
where
<VV_name> is the name of the virtual volume (vv2) to be added to the primary
volume group (Group2). You also need to specify the target name
<target_name> for
that volume group (InServ1)and the name of the secondary volume (vv2.remote).
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 InServ2:
# setrcopygroup period <value> <target_name> <group_name>
On InServ2:
# admitrcopyvv VV_name group_name target_name:sec_VV_name
