The next step is to locate the commands that can be used to re-create the Volume Group and Volumes on this drive group. When PUT initializes an array, it creates a config file that contains all of the commands that can recreate the same array configuration if needed. This file is located on the PUT master node in the directory /var/opt/teradata/support/ArrayConfiguration with a filename of the form ArrayConfiguration.[ArrayName].cfg.

For this example, the array we are working on is named "DAMC001-2-2", so the filename would be ArrayConfiguration.DAMC001-2-2.cfg. The disks with locations 1,11 and 3,11 had failed, which in turn caused the failure of volume 22 inside volume group 23.

Search the ArrayConfiguration file for a command of the form:

create volumeGroup drives=(driveLocation1 driveLocation2) RAIDLevel=1 userLabel="[VolumeGroupNum]" …

and

create volume volumeGroup=”[VolumeGroupNum]” userLabel=”[VolumeNum]”  …

Note, in the ArrayConfiguration file, the 'create volume' command will immediately follow the 'create volumeGroup' command.

For this example, searching for the commands that created volume group 23 and volume 22, we find the following:

create volumeGroup drives=(1,11 3,11) RAIDLevel=1 userLabel="23" securityType=enabled dataAssurance=none;

create volume volumeGroup="23" userLabel="22" owner=A segmentSize=1936 dssPreAllocate=false dataAssurance=enabled mapping=none;

See the commands found in the ArrayConfiguration file as you will need this information in the next step.
