Symptoms

The EPIC database protection job using PowerMax Storage Direct fails with error ABVSD0018.The following log entries appear in varlog/brs/sdmng.log: errorCode: "ABVSD0018" errorMessage: "An error occurred while reading the data from queue. Error code is 81." Additional log messages indicate: Backup session failed for the session id: <session_id> Volume configuration may not be supported or disk may be encrypted.

Cause

PowerProtect Data Manager experiences a sudden increase in writer wait time while waiting for the reader to send data. Certain data chunks see wait intervals ranging between 800 and 2000 seconds, leading to timeout errors. Slow read performance from the PowerMax volume typically causes this behavior.

Resolution

To mitigate the issue: Edit the following configuration file on the PowerProtect Data Manager system: /usr/local/brs/lib/sdmng/config/application.yml Locate the parameter: READER_TIMEOUT_IN_SECONDS: 300 Update it to: READER_TIMEOUT_IN_SECONDS: 900 Restart the sdmng service to apply the change. # sdmng restart ...wait for service to restart & check status # sdmng status This increases the timeout threshold, allowing the system more time to complete read operations and reducing the likelihood of ABVSD0018 errors.
