Administering Centera Disk Libraries
Before configuring the library, the Centera cluster information must be added and successfully detected, using the Library and Drive Configuration window. Cluster information includes the IP address or DNS name of the Centera cluster and the port ID through which the library must be accessed. See Add Centera Cluster Information and Configure Centera Cluster as a Disk Library for step-by-step instructions.
Also, appropriate Centera access requirements (for example, configuration of Centera Pea file) must be fulfilled before using the Media Agent software to backup data to Centera.
Once configured, the Centera library supports all the operations supported by a disk library. Note that Centera is supported as a regular library; shared library configurations are not supported.
From the CommCell Browser, you can perform the following operations on a Centera disk library:
You can view the properties and modify the library name, low watermark and the status of a Centera disk library from the CommCell Console.
You can also view the properties and modify the maximum number of readers, maximum number of writers, maximum number of readers and writers and the status of a mount path from the CommCell Console.
In addition, you can also view the configuration and space information associated with a Centera disk library. See View the Space and Access path Information for a Centera library for step-by-step instructions.
You can view the contents of a specific mount path. This feature can be used to view a list of data protection operations residing in the mount path. All the details associated with the data protection operation(s) available in the media are displayed. This includes the following:
See View the Contents of a Mount Path for step-by-step instructions.
The delete contents option can be used to logically delete the contents of a mount path.
This operation deletes the data from the CommServe database. Note that this operation does not free-up the disk space in the mount path. A Data Aging operation must be run subsequently to free-up the disk space.
This option can be used to make media available to complete an important data protection job when there is no free-space available in the library.
CAUTION Extreme caution should be exercised while using this option as once deleted, the contents of the mount path will not be available for data recovery operations. |
The Delete Contents operation is recorded in the Audit Trail.
See Delete the Contents of a Mount Path for step-by-step instructions.
You can migrate a disk library to another MediaAgent within the CommCell. Consider the following while performing this operation:
See Migrate a Disk Library for step-by-step instructions.
You can remove the Centera Cluster information using the Library and Drive Configuration window. See Remove Centera Cluster Information for step-by-step instructions
Deconfiguring a Centera disk library is similar to deconfiguring a disk library. See Deconfigure a Disk Library for step-by-step instructions.
This software supports all these modes by setting the retention property on each data object when submitting a Cclip which is used to register the data with Centera for storage. The Cclip reflects a retention date that is based on the number of retention days on the Storage Policy Copy Properties. Once the date is set on the Cclip, changing the Storage Policy Copy to a shorter retention will not change the existing Cclips and attempts to prune the data on the device will be denied until it is aged based on the Cclip value. (For information on Cclips and setting-up the data retention on Centera Clusters, refer to the Centera documentation.)
