Protecting data during pool shortages
To protect data from reading and writing to the DP-VOL when the pool is full, you can apply access attributes to a volume. To do this, you need to enable the Data Retention Utility by ensuring the license is installed and by using system option mode 729. This protection method applies the Protect attribute to the DP-VOL to protect volumes against write operations when the pool is full.
The Protect attribute is applied to the DP-VOL and is used in conjunction with other software products. When the Protect attribute is applied to the DP-VOL, Permitted appears in the S-VOL field and 0 day appears in the Validation field of the Data Retention Utility window. However, when the Protect attribute is added to the DP-VOL with the S-VOL unacceptable attribute available in the Data Retention Utility, Not Permitted appears in the S-VOL field in the Data Retention window.
