Changing an access attribute to read-only or protect

When changing an access attribute to read-only or protect, observe 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.

• The volume must not be one of the following:

• Volumes that do not exist

• Volumes that are configured as command devices

• TrueCopy secondary volumes (*)

• Universal Replicator secondary volumes (*) or journal volumes

• ShadowImage secondary volumes (*)

• Thin Image secondary volumes (*)

• Pool volume

• Thin Image virtual volume

*Note: The access attribute of secondary volumes may be changed depending on the pair status.

To change an access attribute to read-only or protect:

1. Perform one of following to display the Data Retention window.

For Hitachi Command Suite:

1. On the Resource tab, expand the Storage Systems tree. Right click the target storage system, then select Other Function.

2. Click Actions > Other Function > Data Retention to open the Data Retention window.

For Storage Navigator:

• Click Actions > Other Function > Data Retention to open the Data Retention window.

2. Click to change to Modify mode.

3. Select an LDKC number in the LDKC list, select a group that the CU belongs in the CU Group list, then click a CU in the tree.

4. Right-click a volume whose access attribute you want to change. You may select multiple volumes.

5. Select Attribute, then select Read Only or Protect.

6. In the Term Setting dialog box, specify the retention term. During this period, the access attribute cannot be changed to read/write. You can enter the number of years and days, or select Unlimited. The retention term can be extended but cannot be shortened.

• years: Specify the number of years within the range of 0 to 60. One year is counted as 365 days, whether the year is a leap year.

• days: Specify the number of days within the range of 0 to 21900.

For example, if 10 years 5 days or 0 years 3655 days is specified, the access attribute of the volume cannot be changed to read/write in the next 3,655 days.

7. Click OK to close the dialog box.

8. In the Data Retention window, click Apply to apply the setting.

To extend the retention term later, open the Data Retention window, right-click the volume, then select Retention Term.
