重置振荡错误

振荡误差本质上是表面的，不会导致任何问题。当客户执行 RCM 升级、部署新服务或执行任何频繁地使主机启动和关闭时，PowerFlex 会将其报告为振荡错误。

提醒：运行下面的重置命令后，振动错误消息可能仍然存在。这样做的原因是它们可以缓存在当前的主 MDM 上。在这种情况下，清除警报的最后一步需要将主 MDM 切换到辅助 MDM。此过程是一种侵入性操作。在继续之前，必须与客户确认此修正步骤。请参阅戴尔文章 PowerFlex 演示服务器：无法清除报告的网络警报192262了解更多信息（需要以已注册的戴尔支持用户身份登录才能查看文章）。


各种振荡错误故障计数器可以重置为零。当您已修复问题并希望确保警报在系统中不再处于活动状态时，以下命令非常有用。我们可以重置整个系统、每个保护域或每个存储池的计数器。
  • 通过 SSH 连接到主 MDM 以 运行下面的重置命令：

语法

scli --reset_oscillating_failure_counters (--failure_counter (((-- protection_domain_id | --protection_domain_name ) | --all_sds) | --all_sdc | (((----protection_domain_id | -- protection_domain_name) --storage_pool_name ) | --storage_pool_id ) | --all_devices) | --all_counters)

参数

--failure_counter <COUNTER>


振荡故障计数器复位为零;计数器按如下分组：

  • 计数器组 A（MDM 和 SDS 相关计数器）：
mdm_sds_network_disconnections

sds_sds_network_disconnections

sds_decoupled

sds_configuration_failures

sds_receive_buffer_allocation_failures
  • 计数器组 B（SDC 相关计数器）：
sdc_mdm_network_disconnections

sdc_sds_network_disconnections

sdc_long_operations

sdc_memory_allocation_failures

sdc_socket_allocation_failures
  • 计数器组 C（SDS 设备相关计数器）：
sds_device_long_successful_ios
  
--protection_domain_id <ID>         Protection Domain ID

--protection_domain_name <NAME>   - Protection Domain name

--storage_pool_name <NAME>        - Storage Pool name

--storage_pool_id <ID>            - Storage Pool ID

--all_sds                         - Reset the counter parameters on all SDSs

--all_sdc                         - Reset the counter parameters on all SDCs

--all_devices                     - Reset the counter parameters on all SDS devices

--all_counters                    - Reset all counters to zero


示例（所有 SDC、SDS、MDM 计数器）：

# scli --log in --username admin –password <MDM Password>

# scli --reset_oscillating_failure_counters --all_counters --all_sdc

# scli --reset_oscillating_failure_counters --all_counters --all_sds

# scli --reset_oscillating_failure_counters --all_counters --all_mdm


示例（特定计数器）：

# scli --log in --username admin –password <MDM Password>

# scli --reset_oscillating_failure_counters --failure_counter mdm_sds_network_disconnections --all_sds


其他信息 - 具体柜台详细信息：

sds_configuration_failures              - measures the number of MDM's failures to configure an SDS when connecting to an SDS (failures in the reconfiguration phase)
sds_receive_buffer_allocation_failures  - measures the number of times SDS fails to allocate buffer for receiving messages

sdc_mdm_network_disconnections
sdc_sds_network_disconnections
sdc_long_operations                     - measures the number of SDC RPC operations which took more time than a predefined threshold
sdc_memory_allocation_failures          - measures the number of memory allocation failures in each SDC
sdc_socket_allocation_failures          - measures the number of socket allocation failures in each SDC

sds_device_long_successful_ios          - measures the number of successful IOs to an SDS device that took longer than a predefined threshold

默认阈值为 250 毫秒。
