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

The Volume Retention license key must be installed. The Volume Retention software contains license
keys for Volume Retention and Data Retention program products.
Volume Retention operations are performed in a Remote Web Console secondary window. For
more information about enabling and using secondary windows, see the HP XP7 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
Do not 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 primary volume (P-VOL) and the secondary 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 installed, you must
do either of the following:
◦
Change the access attribute of the P-VOL to Read/Write.
◦
Uninstall 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.
If a remote copy pair is suspended during a Continuous Access Synchronous Z or Continuous
Access Journal Z copy operation and you want to enable the S-VOL read option on the RCU
(mode 20), you must ensure that the access attribute of the S-VOL is Read/Write before you
enable the S-VOL read option. If the access attribute of the S-VOL is Read-Only, mode 20 will
