In Table 1, for example, you cannot change the access attribute of volume #01 to Read/Write in the

next 2,190 days because the retention term for this volume is 2,190 days. If you need to change the

access attribute of this volume to Read/Write, you must ask your HP service representative to do so.

Expiration Lock Function

You will be able to change the access attribute of a volume from Read Only to Read/Write or from

Protect to Read/Write when the retention term ends. Retention Term displays 0 days when the retention

term is over. In Table 1, for example, you can change the access attribute of volume #02 to Read/Write

because the retention term is over. However, if you enable expiration lock in the Data Retention

window, attempts to change Read Only volumes or Protect volumes to Read/Write volumes will fail

even when the retention term is over. Expiration lock is disabled when you start Data Retention Utility

for the first time. To enable expiration lock, see Prohibiting Changes to Read/Write Even When the

Retention Term is Over (Enabling/Disabling the Expiration Lock Function) on page 22.

S-VOL Disable Function

When storage system copy software copies data, the data on the copy destination volume (also known

as the secondary volume) will be overwritten. If a volume containing important data is specified as a

secondary volume by mistake, storage system copy software can overwrite important data on the

volume and you could suffer loss of important data. Data Retention Utility enables you to avoid such

loss of data.

If you assign the S-VOL Disable attribute to a volume, storage system copy software will be unable to

copy data to that volume. Also, if you assign the Read Only attribute or Protect attribute to a volume

as an access attribute, any other write operations will be prohibited on that volume. For example,

business application software will be unable to write data to such a volume.

To prohibit storage system copy software from copying data to a volume, but do not want to prohibit

other write operations to the same volume, you must ensure that the volume has the Read/Write

attribute. Also, you must assign the S-VOL Disable attribute to that volume to prevent storage system

copy software from copying data to the volume. For detailed information about how to do this, see

Protecting Logical Volumes Against Storage System Copy Operations (Setting the S-VOL Disable

Function) on page 22.

Notes:

• Storage system copy software refers to HP StorageWorks XP XP Continuous Access Software, HP

StorageWorks XP XP Continuous Access Journal Software, HP StorageWorks XP XP Business Copy

Software, and HP StorageWorks XP Snapshot Software.
