Repository for Device Manager: Manages system and hardware information about storage subsystems
managed by Device Manager.

Repository for Command View XP AE Suite Common Component: Common to all Command View XP AE
Suite software. It manages data displayed in display areas common to Web client series products. If a
Web client or CLI client gives an instruction to perform a refresh, this repository does not change.

The cache is information that is imported from the Device Manager repositories to a database (repository) for
Tiered Storage Manager.

1-7-2 When to Perform a Refresh

You must perform a refresh:

After changing logical device or hardware configurations (see section

1-7-2-1

).

After registering or performing a migration task (see section

1-7-2-2

).

NOTE:

Tiered Stored Manager automatically performs a refresh when you add or delete a storage domain.

You cannot perform a refresh:

If a storage domain is managed with PSA permissions (an error message displays).

During another operation, including another refresh (an error message displays).

NOTE:

It takes some time to refresh the Tiered Storage Manager storage domain because the refresh

operation updates the database (repositories).

1-7-2-1 After Changing Logical Device or Hardware Configurations

If you do not perform a refresh after changing configurations, data will be migrated to the wrong location.

Example:

a.

LDEV 2:01 is externally connected to StorageWorks XP1024.

b.

A refresh is performed by using Tiered Storage Manager.

c.

The external connection target of 2:01 is changed to StorageWorks XP512 by using Remote Web
Console.

d.

2:01 is migrated by using Tiered Storage Manager.
In the Web client display, 2:01 still matches StorageWorks XP1024. The migration target of 2:01 still
appears to be StorageWorks XP1024. However, migration to StorageWorks XP512 has actually been
performed.

1-7-2-2 After Registering or Performing a Migration Task

If you do not perform a refresh after registering or performing a migration task, an error might occur in the
subsystem.

NOTE:

After you perform a refresh, the latest refresh data and time display in the List Objects – Storage

Domain Name subwindow. The information in the navigation frame is also updated.

1-7-3 Refresh Types and Scopes

There are four refresh operation types:

Refresh to synchronize information in the storage subsystems with the repository for Device Manager

Refresh to synchronize the repository for Device Manager with the repository for Tiered Storage Manager

Refresh to synchronize the repository for Tiered Storage Manager with the HiCommand common
repository

Refresh to synchronize the HiCommand common repository with the browser

Performing a refresh to synchronize information in the storage subsystems with the repository for Device
Manager

This refresh synchronizes information in the storage subsystems with the storage subsystem configurations
held by Device Manager.

If an attempt is made to refresh Tiered Storage Manager when an inconsistency exists between the
information in the storage subsystems, the storage configuration information held by Device Manager,
and the storage configuration information held by Tiered Storage Manager, a message asking whether
you want to refresh Device Manager is displayed. Click the OK button if you want to refresh Tiered
Storage Manager and Device Manager.
