Release Notes - 4.2.0

What's Fixed?​

Disaster Recovery​

Data Security​

  • CYBER-573: VAST 5.2 Config Replication Issue

    Fixed configuration replication failures in VAST 5.2 that occurred due to missing policy_id field requirements. The system now properly handles the new VAST 5.2 API requirements for view creation.

  • CYBER-916: VAST Configuration Replication 502 Bad Gateway

    Resolved 502 Bad Gateway errors during configuration replication when multiple jobs for protected paths were enabled simultaneously. The system now better handles concurrent API requests to VAST clusters.

Data Security​

  • CYBER-881: ECA Qumulo Syslog Processing Failures

    Fixed issues where large numbers of "Failed to process syslog event" alarms were generated for Qumulo environments. The system now properly processes syslog events without generating excessive false alarms.

  • CYBER-906: Qumulo Lockout Reporting Accuracy

    Corrected an issue where Ransomware Defender for Qumulo incorrectly reported lockout failures even when SMB session closures were successful (returning 200 status codes). The system now accurately reflects lockout status.

  • CYBER-898: Easy Auditor Query Limit Enforcement

    Fixed an issue where Easy Auditor reports showed more results than the maximum limit of 50,000 set in the query builder. The system now properly enforces the configured result limits.

  • CYBER-774: NFS Manual Lockout for Monitor Mode

    Added the ability to manually enforce NFS export lockouts (read-only access) when NFS exports are in monitor mode. System administrators can now manually lock out users via the UI when threats are identified.

  • CYBER-642: VAST Cluster Database Cleanup

    Enhanced database cleanup processes when VAST clusters are brought back online after maintenance. The system now properly maintains database consistency and provides alerts when connections are lost.

System and Performance​

  • CYBER-694: PowerScale Task Optimization

    Disabled default tasks related to PowerScale (such as ClusterConfigReport and QuotaRequestsReport) in VAST/Qumulo-only environments to improve system performance and reduce unnecessary processing.

  • CYBER-722: Cluster Type Display Accuracy

    Fixed login logs to display the correct cluster type instead of showing "Isilon-Cluster" for VAST and Qumulo systems.

Known Issues​

  • CYBER-1018: File extensions in file filters are updated remotely in 4.2

    The new filters are labelled as Custom instead of Built-In. This change is cosmetic only and does not impact the functionality of the file filters.
