当 iozone 对 NFS 导出执行连续写入时，文件系统操作（如 ls）可能会显示为挂起，因为 Linux NFS 客户端会延迟处理这些请求，直到写入工作负载完成。此行为由 Linux 客户端实施驱动，不是由 Unity 存储系统导致的。

在 Unity OE 5.2.0.0.5.173 中，具有大于 16 KB 的 Kerberos 令牌的用户可能无法访问托管在 Unity NAS 服务器上的 SMB/CIFS 共享。当 SMB 身份验证使用 Kerberos 时会出现此问题，并且问题是由 SMB 会话设置过程中的缺陷导致的，该过程中错误地返回大型 Kerberos 令牌的STATUS_INVALID_PARAMETER错误。此问题已在 Unity OE 5.2.1.0.5.013 （5.2 SP1） 中得到解决。在可以执行升级之前，受影响的用户可能会减少其 Kerberos 令牌大小、使用 NTLM 身份验证或故障切换到 Unity OE 5.1.x 阵列（如果可用）。

即使已成功注册远程系统，复制连接创建或验证也可能失败并显示错误0x6500128。当所需的复制接口缺失、配置不正确或所选复制模式需要源和目标 Unity 系统之间不可用的连接时，通常会发生此问题。在创建或验证复制连接之前，请确保在两个 Unity 系统上配置并操作所有必需的复制接口。

在 Dell Unity OE 5.0.x 中，在同步故障切换操作后显示的恢复确认消息错误地指出将为所有选定的复制会话启动完全同步。这只是用户界面消息传递问题，不会影响实际的复制行为。Dell Unity 开发部门已发现该问题，并计划针对 Dell Unity OE 5.1 进行修复，其中“恢复”摘要消息将正确反映正在执行的复制操作。

本文介绍如何在寻找 CTA 虚拟版本 （VE） 支持时查找 Dell Unity 序列号 （SN），因为使用 Unity 实施 CTA VE 时，没有可用于打开案例的 SN，而是使用 Unity SN。

本文介绍如何在现有证书即将到期或已到期时手动续订 Unity 管理 SSL 证书。它提供了生成、安装和验证新管理证书所需的步骤，以维护对 Unity 管理接口的安全访问，并防止与证书相关的警告或连接问题。

本文帮助存储管理员检查在 NAS 服务器上启用了哪些 Kerberos 加密类型，而无需装载 NAS 服务器。

本文介绍了以错误代码 0x6000001 为特征的 UEMCLI 执行失败，其中系统返回“操作失败”消息，指示访问已被拒绝。

禁用 TLS1.0 时，Unisphere UI 无法以 LDAP 用户身份登录。收到的消息是“登录用户无权访问 Unisphere”。

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 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 "flr::check_if_storage_pool_recovery_is_required_3" warning on Dell Unity arrays. This indicates that a storage pool may require recovery. It covers the cause of the warning, how to assess pool health, and recommended actions before proceeding with system operations or upgrades.

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.

Dell Unity: Error 14:603b8 NAS Server Degraded

Dell Unity: Unable to enable Offline Availability of SMB shares.

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.
