Symptoms

Clips are failing to migrate to the ECS from Centera with "ERROR_RETENTION_INCORRECT."

Cause

Scenario 1:If an object's retention period is outside of the bounds that are specified on the bucket, then an attempt to write the object fails. When using retention policies, Selecting Infinite for Minimum Fixed Retention Period means that all retention values on all objects must be infinite.Selecting infinite for Maximum Fixed Retention Period means that there is no maximum limit. Min/max retention constrains are applied to any C-Clip written to a bucket. If a clip is migrated by any SDK-based third-party tool the retention should be within bounds, otherwise an error is thrown. Scenario 2:There are retention class policies defined on Centera. You can verify this by asking the customer to provide you with the below command from Centera: Config# show retention all

Resolution

Scenario 1:So for example if you had CAS clips with retention of 7 years set on them, you would have to create a bucket with the following retention values: Bucket Retention Period: 0 secondsMinimum Fixed Retention Period: 0 secondsMaximum Fixed Retention Period: 8 yearsMinimum Variable Retention Period: 0 secondsMaximum Variable Retention Period: 0 seconds This way, the retention is within the min/max constraints. Scenario 2:Ask the customer to provide you with the below retention class policies. Start the CLI for Centera. Connect as a user with the compliance or monitor role. Type the command: show retention all The output is similar to: Retention class name Period ------------------------------------------ class 1 5 years class 2 3 months class 3 10 years You then must add all these retention class policies to namespace retention policies on the ECS side. Ask the customer/PS to try the migration again after adding the namespace retention policies on the ECS side.
