升级前运行状况检查 （PUHC） 脚本失败。tar 报告“This does not look like a tar archive”（这看起来不像 tar 存档）和标头错误，这是由于浏览器错误地解压缩 tar.gz 文件造成的。

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'.

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.

When creating a Proxy NAS Server, if the NAS Server name contains spaces, the addition fails.

This article explains the "dm::check_filesystems_health_4" warning during a Unity pre‑upgrade health check (PUHC). The PUHC indicates potential file system issues to review before upgrading. It outlines the cause, verification steps, and recommended remediation to ensure that the system is healthy before upgrading.

Call home alert 14:170050 The license has expired

A dial home alert (14:38004e) has been generated indicating that the “service” user home directory has exceeded its allocated disk space, potentially impacting system operations such as core dump file storage.

Issue: Changing attribute access to a host like read-only, R/W, or root, sends an error of having a duplicate host in the list.

Unity supports the ability to host multiple tenants on a single system for service providers who would like to isolate group of VLANs from the rest, also tenants helps admins as NAS servers belonging to same tenant will have the tenant's name visible beside each NAS server which eases the NAS servers grouping and classification. NAS servers created with access to the tenant will have access to the VLANs included in the tenant. Dell Unity’s flexible pool-based architecture also enables the ability to separate each tenant onto their own pools for separation at the drive level, if necessary.

SFTP disconnection seen post Unity Code Upgrade to OE 5.0.7 version

The file system is offline and requires recovery. This may be caused by the pool being offline. Fix the issue on the pool first. If the problem still exists, contact your service provider.

Critical alert: An I/O module in the Disk Processor Enclosure has faulted and must be replaced.

The I/O module is powered off. Try rebooting the Storage Processor (SP). If the I/O module remains powered off after a reboot, you may have to replace the I/O module. (Dell Correctable)

在文件系统创建或文件系统装载期间，如果启用了树配额，则存储处理器 （SP） 可能会意外重新启动或文件系统可能会离线。 有时，存储处理器在意外重新启动后仍处于服务模式。
