重設振蕩錯誤
振蕩誤差為表面錯誤,不會造成任何問題。當客戶執行 RCM 升級、部署新服務或任何能使主機上下跳動的頻率時,PowerFlex 會將此報告為振盪錯誤。注意:執行以下重設命令後,振盪錯誤的訊息可能會持續出現。這樣做的原因是它們可以緩存在當前的主要 MDM 上。在這種情況下,清除警示的最後一步需要將主要 MDM 切換至次要 MDM。此程序為侵入性動作。此補救步驟必須與客戶確認後,才能繼續。請參閱 Dell 文章 PowerFlex 簡報伺服器:無法清除已回報的網路警示192262以取得更多資訊 (需要以已註冊的 Dell 支援使用者身分登入才能檢視文章)。
各種振蕩誤差故障計數器可以重置為零。當您修正問題並想要確保警示在系統中不再處於作用中時,下列命令非常有用。我們可以為每個保護網域或每個儲存集區重設整個系統的計數器。
- SSH 至主要 MDM 以執行以下重設命令:
語法
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)
參數
--failure_counter <COUNTER>
振蕩故障計數器複位至零;計數器分組如下:
- 計數器組 A (MDM 和 SDS 相關的計數器):
mdm_sds_network_disconnections sds_sds_network_disconnections sds_decoupled sds_configuration_failures sds_receive_buffer_allocation_failures
- 計數器組 B (SDC 相關計數器):
sdc_mdm_network_disconnections sdc_sds_network_disconnections sdc_long_operations sdc_memory_allocation_failures sdc_socket_allocation_failures
- 計數器組 C (SDS 設備相關計數器):
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
範例 (所有 SDC、SDS、MDM 計數器):
# 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
範例 (特定計數器):
# scli --log in --username admin –password <MDM Password>
# scli --reset_oscillating_failure_counters --failure_counter mdm_sds_network_disconnections --all_sds
其他資訊 - 特定計數器詳細資訊:
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
