Designing Disaster Recovery Clusters using Metroclusters and Continentalclusters, Reprinted October 2011 (5900-1881)

## Node World Wide Name (WWN)which both contain the DR groups##
## defined under the <dr_group_info> tag. You can define as ##
## many DR groups as you need, but each DR group must belong ##
## to only one of the storage pairs. A storage pair can have ##
## a maximum of 64 DR groups. ##
## Note that you can find storage Node World Wide Names form ##
## the front panel of your EVA controllers or from the ##
## ‘Initialized Storage Properties’ page of command view ##
## EVA through your Web browser. ##
## Below is an example of a configuration with two storage ##
## pairs (4 storage units). The first storage pair contains ##
## 2 DR groups and the second pair contains 1 DR group. ##
## <storage_pair_info> ##
## “5000-1FE1-5000-4280” Enter first storage WWN in double ##
## quotes. ##
## “5000-1FE1-5000-4180” Enter second storage WWN in double ##
## quotes. ##
## <dr_group_info> ##
## “DR Group - Package1” Enter a DR group name in double ##
## quotes. ##
## “DR Group - OracleDB1” Enter a DR group name in double ##
## quotes. ##
## <storage_pair_info> ##
## “5000-1FE1-5000-4081” Enter first storage WWN in double ##
## quotes. ##
## “5000-1FE1-5000-4084” Enter second storage WWN in double ##
## quotes. ##
## <dr_group_info> ##
## "DR Group - Package2” Enter a DR group name in double ##
## quotes. ##
## Note:Since '#’ meant a start of a comment, you cannot ##
## include the ‘#’ in any <storage_pair_info>, ##
## <dr_group_info>, storage name and DR group name. ##
## ##
## Note: All the storage and DR Group names should be ##
## enclosed in double quotes (““), otherwise the ##
## evadiscovery command will not detect them. ##
## Enter your MC EVA Storage pairs and DR Groups under the ##
## # dashed lines: ##
## ----------------------------------------------------------##
## <storage_pair_info> ##
## “5000-1FE1-5000-00DF” ##
## “5000-1FE1-5000-00DE” ##
## <dr_group_info> ##
## “DR Group 1” ##
## “DR Group 2” ##
## “DR Group 3” ##
## “DR Group 4” ##
Creating the Storage Map File
After completing the EVA Storage Cells and DR Groups configuration file, use the EVA discovery
utility to create or modify the storage map file stored on the configuration node.
# evadiscovery -f /etc/dtsconf/mceva.conf
% Verifying the storage systems and DR Groups .........
Generating the mapping data .........
Adding the mapping data to the file /etc/dtsconf/caeva.map .........
The mapping data is successfully generated.
The command generates the mapping data and stores it in /etc/dtsconf/caeva.map
The mapping file/etc/dtsconf/caeva.map contains information of the Management Servers
as well as information of the EVA Storage Cells and DR Groups.
