5 Configuring access attributes
Volume Retention is required to assign access attributes to volumes.
Access attributes strategies
By default, all the volumes are subject to read and write operations by hosts. With Volume Retention,
you can assign access attributes to volumes that restrict read and/or write operations as needed.
By properly setting these attributes, you can prevent unauthorized access to data and avoid the
possibility of data being damaged, lost, or leaked.
Volume Retention requirements
Before using Volume Retention, confirm that the following program products have been installed
in Remote Web Console.
• Volume Retention
The storage system must be configured to conform to all hardware devices, microcode, and the
Remote Web Console requirements. In addition, the Volume Retention license key of must be
installed in the Remote Web Console. The Volume Retention software contains license keys for
Volume Retention and Volume Retention program products. For more information on license keys
or the program product installation, see the HP XP P9000 Remote Web Console User Guide.
Access attribute restrictions
Notes on using Volume Retention with other program products follow.
Performance Monitor and Auto LUN
Some program products may be set to start automatically at a certain time. For example, if an
automatic start time is set in Performance Monitor or Auto LUN, monitoring begins at the specified
time. If another product has been set to start automatically, you must take one of these actions.
• Perform Volume Retention operations when the other program is not running.
• Reset the specified start time of the other product.
Continuous Access Synchronous Z and Continuous Access Journal Z
• It is not recommended to assign an access attribute to a volume that is in use by Continuous
Access Synchronous Z or Continuous Access Journal Z. If you assign an access attribute to
such a volume, the job may end abnormally. If you still want to assign an access attribute to
such a volume, you must assign the same access attribute to both the main volume (P-VOL)
and the remote volume (S-VOL).
• When creating a Continuous Access Synchronous Z or Continuous Access Journal Z pair and
using a read-only volume as the P-VOL, use an S-VOL on a storage system on which Volume
Retention is enabled.
If the S-VOL must be on a storage system on which Volume Retention is not enabled, you must
do either of the following:
◦ Change the access attribute of the P-VOL to Read/Write.
◦ Disable Volume Retention on the main site.
• If you use Continuous Access Synchronous Z or Continuous Access Journal Z to create a pair,
the P-VOL and the S-VOL will have the same access attribute. Even if you suspend or delete
the pair, access attribute for these volumes will not change.
