To restore cluster settings:

Use the banner breadcrumbs to navigate to the cluster where the restore operation is applied.
On the Restore Settings page, click the Browse button to open the File Upload window.
Navigate to the backup file used to restore the cluster settings. This file has an .xmi extension.
Add the file name to the File name field.
Click Open or press Enter from your keyboard.
Click Show File to review the cluster settings that are contained in the backup file. The backup file can contain any of the following settings, but only those settings that are defined by the backup file are shown.
Constructs

When these settings are restored, new settings are added and existing settings are modified, but no settings are deleted.
Select this check box to restore all of the displayed constructs.
Storage Groups

Select this check box to restore defined storage groups.

Management Classes

Select this check box to restore defined management classes.
Important: Management Class settings are related to the number and order of clusters in a grid. Take special care when you restore this setting. If a Management Class is restored to a grid that has more clusters than the grid had when the backup was performed, the copy policy for the new cluster or clusters is set as No Copy. If a Management Class is restored to a grid that has fewer clusters than the grid had when the backup was performed, the copy policy for the now-nonexistent clusters will be changed to No Copy. The copy policy for the first cluster will be changed to RUN to ensure that one copy exists in the cluster.

If cluster IDs in the grid differ from cluster IDs present in the restore file, Management Class copy policies on the cluster are overwritten with the policies from the restore file. Management Class copy policies can be modified after the restore operation completes.

Note: If the backup file was created by a cluster that did not define one or more scratch mount candidates, the default scratch mount process is restored. The default scratch mount process is a random selection routine that includes all available clusters. Management Class scratch mount settings can be modified after the restore operation completes.

If Synchronous Mode Copy is restored, settings for the options "defer on write failure" and "open both copies on private mount" are also restored.

If Time Delayed Mode Copy is restored, settings for the options "set time until eligible for copy" and "starting value" are also restored.

Storage Classes

Select this check box to restore defined storage classes.

Data Classes

Select this check box to restore defined data classes.
Note: If this setting is selected and the cluster does not support Logical WORM, the Logical WORM setting is disabled for all data classes on the cluster.
Media type volume sizes are restored based on the restrictions of the restoring cluster. The following volume sizes are supported:

1000 MiB

2000 MiB

4000 MiB

6000 MiB

25000 MiB
Tape Partitions

Select this check box to restore defined tape partitions.
Note: If a partition exists with the same name or if the maximum number of partitions is reached, you cannot restore the partitions.

Inhibit Reclaim Schedule

Select this check box to restore Inhibit Reclaim Schedules that are used to postpone tape reclamation.

A current Inhibit Reclaim Schedule is not overwritten by older settings. An earlier Inhibit Reclaim Schedule is not restored if it conflicts with an Inhibit Reclaim Schedule that currently exists.
Note: If the backup file was created by a cluster that did not possess a physical library, Inhibit Reclaim Schedules settings are reset to default.

Library Port Access Groups

Select this check box to restore defined library port access groups.
Note: This setting is available only when all clusters in the grid operate at microcode level 8.20.0.xx or later.

Library port access groups and access group ranges are backed up and restored together.

Categories

Select this check box to restore Fast Ready Categories that are used to group virtual volumes.

Physical Volume Pools

Select this check box to restore physical volume pool definitions.
Note: If the backup file was created by a cluster that did not possess a physical library, physical volume pool settings are reset to default.

Physical Volume Ranges

Select this check box to restore defined physical volume ranges.
Note: If the backup file was created by a cluster that did not possess a physical library, physical volume range settings are reset to default.

Security Settings

When these settings are restored, new settings are added and existing settings are modified, but no settings are deleted.

Select this check box to restore defined security settings, including the following:

Session Timeout

Specifies the number of hours and minutes the management interface can be idle before the current session expires and the user is redirected to the login page.

Account Expiration

Defines whether and when policy accounts can expire. This setting includes the number of days a password that is used by a policy account can be used before it expires.

Account Lock

Defines whether and when policy accounts can be locked after a number of successive incorrect password attempts. This setting includes the maximum number of successive times a login attempt can fail before a user is locked out.

Roles & Permissions

When these settings are restored, new settings are added and existing settings are modified, but no settings are deleted.

Select this check box to restore defined custom user roles. TS7770 Data at Rest Encryption

Encryption Key Server Addresses

Select this check box to restore defined encryption key server addresses. If a key server address is empty at the time the backup is performed, when restored the port settings are the same as the default value. Encryption key server address settings that can be restored include: TS7770 Data at Rest Encryption

Cluster Network Settings

Select this check box to restore the defined cluster network settings.
Important: Changes to network settings affect access to the TS7700 Management Interface. When these settings are restored, the network is reset. No TS7700 Grid communication or jobs are affected, but any current users are required to log back on to the TS7700 Management Interface by using the new IP address.

Feature Licenses

When these settings are restored, new settings are added and existing settings are modified, but no settings are deleted.

Select this check box to restore the settings for currently activated feature licenses. After you restore feature license settings on a cluster, it is recommended that you log out then log in to refresh the system.
Note: You cannot restore feature license settings to a cluster different than the cluster that created the ts7700_cluster<cluster ID>.xmi backup file.
Feature license information available for backup includes:

Feature Code

The feature code number of the installed feature.

Feature Description

A description of the feature installed by the feature license.

License Key

The 32–character license key for the feature.

Node

The name and type of the node on which the feature is installed.

Node Serial Number

The serial number of the node on which the feature is installed.

Activated

The date and time the feature license was activated.

Expires

The expiration status of the feature license. Possible values are:

Day/Date

The day and date on which the feature license is set to expire.

Never

The feature is permanently active and never expires.

One-time use

SNMP

Select this check box to restore the settings for simple network management protocols (SNMP).

When these settings are restored, new settings are added and existing settings are modified, but no settings are deleted.

Write Protect Mode Categories

Select this check box to restore the settings for write protect mode categories.

When these settings are restored, new settings are added and existing settings are modified, but no settings are deleted.
After you select the Show File button, the name of the cluster from which the backup file was created is displayed at the top of the page, along with the date and time the backup occurred.
Check the box next to each setting to be restored.
Click the Restore button.
Note: The restore operation overwrites existing settings on the cluster.
A warning page opens and asks to confirm your decision to restore settings. Click YesOK to restore settings or NoCancel to cancel the restore operation.
The Confirm Restore Settings page opens.
Attention: If you navigate away from this page while the restore is in progress, the restore operation is stopped and the operation must be restarted.

Restoring to or from a cluster without a physical library

If either the cluster that created the backup file or the cluster that is performing the restore operation do not possess a physical library, upon completion of the restore operation all physical tape library settings are reset to default. One of the following warning messages is displayed on the confirmation page:

The file was backed up from a system with a physical tape
library attached but this cluster does not have a physical tape library attached. If you restore the
file to this cluster, all the settings for physical tape library will have default
values.

The file was backed up from a cluster without a physical tape
library attached but this cluster has a physical tape library attached. If you restore the file to
this cluster, all the settings for physical tape library will have default
values.

Affected settings include:

Inhibit Reclaim Schedule
Physical Volume Pools
Physical Volume Ranges

Restoring to or from a TS7720D

If you backup or restore settings from or to a cluster with the data deduplication feature (a TS7720D ) but the other cluster does not possess the data deduplication feature (a TS7720 or TS7740) then some construct settings are reset to their defaults.

Affected settings include:

Data Class media types
Storage Classes
