A specific Service Data Collection (SDC) plugin used by APEX AIOps may intermittently trigger multiple PostgreSQL (PSQL) queries during uDoctor scheduled tasks, resulting in high CPU utilization on the Primary Storage Processor for approximately 15 minutes. This issue does not affect manually generated Service Data Collections and is resolved in Unity OE version 5.0.3.

Replication Connection creation can fail with Error 0x6500128 if the required replication interfaces are not configured on both the local and remote Dell Unity systems before the connection is created. Verify that replication interfaces exist and are correctly configured under Data Protection > Replication > Interfaces on both systems. To resolve the issue, remove the failed Replication Connection, create the required replication interfaces on both Unity systems, recreate the Replication Connection, and then create the necessary replication sessions.

In Dell Unity OE 5.0.x, the Resume confirmation message displayed after a Failover with Sync operation incorrectly states that a full synchronization will be initiated for all selected replication sessions. This is a user interface messaging issue only and does not affect actual replication behavior. Dell Unity Development has identified the issue, and a fix is scheduled for Dell Unity OE 5.1, where the Resume summary message will correctly reflect the replication operation being performed.

Access-Based Enumeration (ABE) hides files and folders from users who do not have permission to access them. This enhances security and improves usability by displaying only the resources a user is authorized to view.

On Dell Unity OE 4.2.0 and later, an asynchronously replicated File System or NFS Datastore at the destination may go offline due to a known issue involving file system shrink operations and snapshot replication. Recovery requires assistance from Dell Technical Support or the Recovery Team, and the issue is resolved in Dell Unity OE 4.5 and later.

Dynamic pools in Dell Unity provide improved storage efficiency and flexibility compared to traditional pools by distributing data more evenly across drives and simplifying capacity expansion. However, organizations should understand key considerations such as pool conversion requirements, performance characteristics, and operational impacts before transitioning from traditional to dynamic pools.

This article shows how to find the Dell Unity Serial Number (SN) when looking for CTA Virtual Edition (VE) support, since CTA VE, when implemented with Unity, has no SN to open a case with, instead the Unity SN is used.

The system encountered an unexpected error when running health checks. After upgrading to UnityOS 5.5.2 or 5.5.3, Unity Connectivity Services failed.

This article explains how to manually renew the Unity Management SSL certificate when the existing certificate is nearing expiration or has already expired. It provides the steps required to generate, install, and verify a new management certificate to maintain secure access to the Unity management interfaces and prevent certificate-related warnings or connectivity issues.

There are many reasons for not being able to renew or remove a VASA certificate. This article covers only the attempt to renew or remove when the Certificate Validation fails due to "Certificate Chain too long".

A Dell Unity OE upgrade may fail to resume after being paused if management services switch to a different Storage Processor (SP) than the one holding the upgrade files. Reboot the active SP so the SP containing the upgrade image becomes primary, then retry or resume the upgrade.

A Dell Unity software upgrade fails with 'Health Check Error:check_replication_health_2, check_replication_health_5'. The software update could also fail with 'Warning: check_replication_health_4'.

The Storage Processor (SP) experienced an unexpected panic and reboot due to a SIGSEGV (Segmentation Fault). This condition indicates that a process attempted to access memory that was unavailable or invalid, causing the operating system to terminate the process and trigger the SP panic.

Dial home alert for 14:6033c OR 14:6033d

Initiators are not registered to any of the hosts.

Upon Dell EMC Unity Code upgrade from 4.x.x to 5.x.x, certain drives running C342 FW can be exposed to drive unavailability due to firmware issue.

A dial home test message is sent via ConnectHome.

When a Unity system initiates a call home to open a service request for a support issue, it sends the customer's contact information along with the alert message. This simplifies the process for Technical Support engineers to contact the appropriate individuals. Up-to-date contact information ensures that Technical Support has the most accurate information for contacting the customer in response to a support issue. Dell Technologies recommends keeping the primary contact's information up to date in Unity Unisphere. This article shows how to do so.
