topology with two Continuous Access links. The sync Continuous Access link, is between DC1 and DC2 and the other link, the journaling Continuous Access link, is between DC2 and DC3. There is no physical Continuous Access link present between DC1 and DC3 but a phantom device group must be present between DC1 and DC3.

2. multi-target-Bi-Link: When the package is configured for 1:2 or multi target topology with two Continuous

 

Access links. One, the sync Continuous Access link, is

 

between DC1 and DC2 and the other, the journal

 

Continuous Access link, is between DC1 and DC3.

 

There is no physical Continuous Access link present

 

between DC2 and DC3 but a phantom device group

 

must be present between DC2 and DC3.

DC1_NODE_LIST

Comma separated list of all node names that are in data

 

center one (DC1). The node list should begin and end with

 

quotation marks. For example, DC1_NODE_LIST=”node1,

 

node2”.

 

This parameter is not required to be set for a package

 

configured for two data centers.

DC2_NODE_LIST

Comma separated list of all node names that are in data

 

center two (DC2). The node list should begin and end with

 

quotation marks. For example, DC2_NODE_LIST=”node3,

 

node4”.

 

This parameter is not required to be set for a package

 

configured for two data centers.

DC3_NODE_LIST

Comma separated list of all node names that are in data

 

center three (DC3). The node list should begin and end with

 

quotation marks. For example, DC3_NODE_LIST=”node5,

 

node6”.

 

This parameter is not required to be set for a package

 

configured for two data centers.

DC1_DC2_DEVICE_GROUP

The Raid Manager device group between DC1 and DC2

 

for this package. This device group is defined in the /etc/

 

horcm<#>.conf file.

 

This parameter is not required to be set for a package

 

configured for two data centers.

DC2_DC3_DEVICE_GROUP

The Raid Manager device group between DC2 and DC3

 

for this package. This device group is defined in the /etc/

 

horcm<#>.conf file. This will be a phantom device group

 

if 3DC_TOPOLOGY=”multi-target-Bi-Link”.

 

This parameter is not required to be set for a package

 

configured for two data centers.

DC1_DC3_DEVICE_GROUP

The Raid Manager device group between DC1 and DC3

 

for this package. This device group is defined in the /etc/

 

horcm<#>.conf file. This will be a phantom device group

 

if 3DC_TOPOLOGY=”multi-hop-Bi-Link”.

 

This parameter is not required to set for a package

 

configured for two data centers.
