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
