Changing an access attribute to read/write

Before changing the access attribute from read-only or protect to read/write, considering the following:

Hitachi Device Manager - Storage Navigator secondary windows must be defined for use in advance. Select Modify from the Data Retention secondary window to set access attributes and prevent other users or programs from changing storage system settings. When you close the secondary window, Modify mode is released. For more information on Hitachi Device Manager - Storage Navigator secondary windows and Modify mode, see the System Administrator Guide.

Do not assign an access attribute to a volume if any job is manipulating data on the volume. If you assign an access attribute to such a volume, the job will possibly end abnormally.

Make sure that the retention term is expired. If expired, the Retention Term column in the Data Retention window shows 0. To change the access attribute to read/write within the retention term, contact the Hitachi Data Systems customer support.

Make sure that Expiration Lock indicates Disable > Enable. If it indicates Enable > Disable, changing to read/write is restricted by an administrator for some reason. Contact the administrator of your system to ask if you can change the access attribute. (See Enabling or disabling the expiration lock)
