Setting Up Remote Copy

InForm OS Version 2.3.1 Remote Copy User’s Guide

3.5.1.5 Setting Up Additional Remote Copy Pairs

For configurations that use multiple Remote Copy pairs (also known as N-to-1 or 1-to-N type

configurations), after following the instructions in Setting Up Unidirectional Remote Copy on

page 3.17, repeat the entire process for each additional pair, up to a maximum of two

(for 1-to-N configurations) or four (for N-to-1 configurations) Remote Copy pairs.

Note that for N-to-1 configurations all pairs must share the same secondary storage server, and

for 1-to-N configurations all pairs must share the same primary storage server. See N-to-1

Restrictions on page 2.43 and 1-to-N Restrictions on page 2.44 for additional information and

restrictions regarding configurations with multiple Remote Copy pairs.

3.5.2 Setting Up Bidirectional Remote Copy

In this section, as illustrated by Figure 3-7 on page 3.26:

■ The members of the Remote Copy pair are an eight-node cluster called InServ1 and a four-

node cluster called InServ2.

■ A virtual volume on InServ1 called vv1 is the only member of Group1.

■ A virtual volume on InServ2 is called vv1_remote and is the only member of

Group1.r112, the secondary group that is automatically created at the same time as

Group1.

Note that vv1 and vv1_remote must be the same size.

■ A virtual volume on InServ2 called vv2 is the only member of Group2.

■ A virtual volume on InServ1 is called vv2_remote and is the only member of

Group2.r125, the secondary group that is automatically created at the same time as

Group2.

Note that vv2 and vv2_remote must be the same size.

NOTE: The transport layer only needs to be set once per system. However, you

should verify the connectivity for each pair in the configuration.
