5. If more storage is required, click Advanced. The Repository resources window
is displayed with a list of available file systems (if they exist).
6.
Select what file systems to use for metadata or user data. Click Ok. The

7. Click Finish. The summary report is displayed and replication is enabled on
ProtecTIER Manager.
Expanding repositories
Complete the tasks in this topic to increase the capacity of a repository.
About this task
Attention: This section provides instructions for increasing the capacity of a
repository.
After the repository is created, the ProtecTIER system enables you to increase the
capacity of the repository. Much like creating the repository, expanding the
repository requires the guidance of a trained ProtecTIER specialist and use of a
wizard for planning repository expansions. You might need to expand the
repository if:
v Your factoring ratio is higher than originally expected and you are running out
of meta data space.
v Your repository needs have expanded beyond the original growth projections
and you are running out of user data space.
The increase capacity steps described in this task appear in the order in which they
should be performed:
1. Plan the expansion using ProtecTIER Manager.
2. Create new file systems or extend existing ones on the backend storage using
the ProtecTIER Service menu and verify that the devices are displayed.
3. Run the Increase Capacity wizard.
Planning an expansion
Complete this task to plan for a repository expansion.
About this task
With the guidance of a trained ProtecTIER specialist, run the Plan repository
increase
wizard to determine the optimum repository size and meta data file
system arrangement for your expanded repository.
To plan a repository expansion:
Procedure
1. Choose Repository > Increase capacity planning. The Increase capacity
planning
window opens.
2. In the Repository size field, select the total physical size, in TB, for the
repository.
Note: If you are expanding the repository only to increase the amount of meta
data space, increase the estimated factoring ratio value, but leave the repository
physical size value unchanged.
