This article explains two methods of upgrading the Unity OE: Unisphere UI and Command Line (uemcli).

This article provides options for when a pool becomes 100% consumed.

This article explains the maximum recommended sustained Input-Output Operations per Second (IOPs) per drive type on Unity arrays.

This article explains the maximum recommended sustained Input-Output Operations per Second (IOPs) per drive type on VNX arrays.

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".

This article describes managing the auto tiering of data in Unity hybrid storage pools through Unisphere UI and Unisphere CLI (UEMCLI).

In Unity OE 5.3.1, the SupportAssist service is designed to attempt automatic recovery when issues arise. However, due to known issues in this version, the service may fail to recover on its own, ultimately requiring manual intervention to restore functionality. Note: This knowledge base article applies to issues observed in Unity OE versions 5.3.x and 5.4.x.

Dell Unity generates a call home alert (14:6033c or 14:6033d) for drivers predicted to exceed end-of-life thresholds.

Error Code 0x7d13001 is a generic Unity management error that can occur during job monitoring, management service operations, or Unity OE upgrade uploads. The error may cause Unisphere operations to fail or become unresponsive and can be accompanied by backend database or management service errors. This article helps identify the underlying cause and provides the appropriate resolution for each known scenario.

Unity reports Call Home Alert 14:38002a or 14:38002b indicating that the system root drive is running low on available space.

Dell Unity: Error "There is less than xx% disk space left in the system disk of the current system" observed during Unity upgrade (User Correctable)

In Unity 5.5, File System (FS) access can be provided using a Network File System (NFS) mount using NFSv3 or NFSv4 file sharing protocols. This is typically done for Logical Unity Numbers (LUN) and NFS datastores with specific mounting parameters and then scripted for various groups of hosts. A directory is created for the mount point when mounting file shares using NFSv4.2. If the directory security label (sec_label) parameter has no data assigned to it, the Unity Service Processors (SP) can panic and reboot unexpectedly.

How to handle the Spare Drive alert message: The system could not start an automatic copy of data from one or more drives in pool Pool(x), because spare drives are not available.

This article describes a possible solution to the problem when the "svc_udoctor" command does not work properly. (Dell correctable)

This article covers the steps required to reimage a Storage Processor (SP) of a Dell Unity array. A Storage Processor reimage reinstalls the Unity operating software on a single SP while preserving the array configuration and customer data. During the procedure, the affected SP is temporarily unavailable and its workloads fail over to the peer SP. In a properly redundant environment, host access remains online with only brief path failover activity expected.

The article describes how to start using UEMCLI on Unity arrays for array management, configuration or monitoring.

This article explains how to manage admin and service account passwords on Dell Unity systems. It provides instructions for changing passwords, unlocking a locked service account, and resetting admin or service passwords when access is lost.

When using UEMCLI on Linux or Microsoft operating systems, certain special characters in passwords may be interpreted by the operating system rather than passed as part of the password. This behavior is expected and is determined by the operating system; refer to the operating system documentation for guidance on supported special characters and character escaping.

Hosts keep disconnecting from the Unity storage system.

Remediation is available for a vulnerability that could be exploited by malicious users to compromise the affected systems.

The Remote Secure Credentials (RSC) option is disabled by default and SupportAssist must be enabled to select it.

The storage resource cannot be modified or deleted because it is participating in a replication session.

Adding or removing a LUN from a Consistency Group (CG) with snapshots fail with Error Code: 0X6000c21

The tables below list the TCP ports required for Unity Replication. These ports enable communication between Unity Replication services and must be accessible across the network for proper replication functionality.

This article describes the procedure for identifying and clearing stuck or suspended batch jobs in Dell Unity when jobs remain in a failed state and cannot be removed through Unisphere.

The System Status Card (SSC) on a DAE has faulted and must be replaced. Alert message: 14:60c1f.
