Symptoms
小型可插拔 （SFP） 在日志中显示缺失一次，之后显示为良好。
如果 SFP 有少量灰尘或未完全插入端口，则已知它们不会被检测到。
它是性能下降的常见因素，因为它会导致持续的断开连接，甚至可能被视为慢漏设备。
在 Unisphere 用户界面中，存储处理器在“SYSTEM” > “Service” > “Service Tasks”中显示为正在重新启动并处于降级状态。
但是，在使用 CLI 的 SSH 终端中，两个 SP 都处于正常模式。
到目前为止，此问题已出现在 Unity OE 版本 4.5.1.0.5.001 中。
例：
service@CKMxxxxxxxx spa:~/user# svc_diag ======== Now executing basic state ======== * System Serial Number is: CKMxxxxxxx * System Model Number is: Unity 500 * System Friendly Host Name is: CKMxxxxxxxx * Current Software version: c4dev_PIE_3786R-4.5.1.0.5.001.1552025209-GNOSIS_RETAIL * Unisphere IP address(es): xx.xxx.xxx.xx xxxx::xxx:xxxx:xxxx:xxxx * SSH Enabled: true * FIPS mode: Disabled * Boot Mode: Normal Mode * Post Faults: 0x0000 * Backend Faults: 0x0000 * Boot Faults: 0x0000 * Rescue Reason: 0x0000 * Rescue reason for code 0x0000 - No faults detected. * SP Service Hint Code: <None>
Cause
安装新的 I/O 模块时会发生此特殊情况。
提交由于非最佳 SFP 而未完成，因此运行状况相关作被暂时禁用（类似于升级期间发生的情况）。
由于运行状况轮询被禁用，系统无法识别存储处理器的正确状态，并报告以前的已知状态“正在重新启动”。
要确认这是同一问题，请验证以下日志： /var/tmp/ptm/ptm.log/EMC/C4Core/log/c4_safe_ktrace.log
可以通过在 SSH 终端上或在分流服务数据收集日志中运行命令来实时查看此信息：
命令/日志 #1：
预期的输出：
cat /var/tmp/ptm/ptm.log
预期的输出：

命令/日志 #2：
并查找与 SFP 或夹层卡相关的事件。
我们可以看到，在安装新的 I/O 模块时出现了一些错误：

并查找与 SFP 或夹层卡相关的事件。
我们可以看到，在安装新的 I/O 模块时出现了一些错误：

Resolution
要解决此问题，请使用下面列出的命令重新提交最初失败的 I/O 模块。
注意：这些命令不需要 root，但需要正常运行的阵列，因此在运行之前，请确认您的阵列完全正常运行，如下所示：
Command #1：
uemcli -no /sys/general healthcheck -output csv -detail
输出示例：
#1 （非最佳） - 在解决显示的错误之前不要继续。
"Error code" "Warning: One or more asynchronous replication sessions, or one or more NAS Server or file system synchronous replication sessions, exist. This could cause problems during upgrade. Pause the replication sessions on the production array prior to starting the upgrade and resume them after completing the upgrade. [Warning Code: platform::check_replication_health_4]" "Warning: One or more NAS servers may not be in a healthy state. You can continue with the upgrade, but it is recommended that you record the error code and contact your service provider. [Warning Code: dm::check_nas_servers_health_3]" Operation completed successfully.
提醒：其中确实提到了“Upgrade”，因为这是在执行无中断升级 （NDU） 之前使用的命令。但是，显示这些消息的原因是阵列（两个 SP）必须重新启动。
Command #2 可能还需要重新启动，这就是为什么此运行状况检查在没有任何 [错误代码：] 的情况下通过很重要的原因。
可以忽略 [警告]，但 Command #2 会提示消息
"Do you still want to continue," 您可以输入“是”。但是，戴尔支持部门的建议是在继续作之前解决运行状况检查中的所有警告和错误。
要重新启动存储处理器，请按照知识库文章 Dell Unity：如何重新启动存储处理器（用户可纠正）
#2（最佳） - 您可以转到命令 #2
"Error code" Operation completed successfully.
命令#2：
svc_change_hw_config -e
预期的输出：
