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
