Symptoms

探索問題發生在 Data Domain 系統上。報告逾時錯誤。之前已發現這些相同的 Data Domain 系統，沒有發生問題。將逾時增加到 1200 只會清除部分 Dell Data Domain 裝置的問題。

Data Domain 收集器記錄會顯示下列一般錯誤：

WARNING -- [2023-02-15 10:59:00 MST] -- PollingUnitPollingGroup::waitAtEndOfPollingCycle(): Polling group 300.EMC-DATA-DOMAIN-BOOST.EMC-DATA-DOMAIN-CIFS.EMC-DATA-DOMAIN-DISK.EMC-DATA-DOMAIN-ENV.EMC-DATA-DOMAIN-FS.GENERIC-INTERFACES.GENERIC-HOST-RESOURCES-PROCESSOR.GENERIC-HOST-RESOURCES-STORAGE.EMC-DATA-DOMAIN-MTREE.EMC-DATA-DOMAIN-NFS.EMC-DATA-DOMAIN-QUOTA.EMC-DATA-DOMAIN-REPLICATION.GENERIC-SYSUPTIME.EMC-DATA-DOMAIN-SYSTEM.EMC-DATA-DOMAIN-VTL is taking too long: Completed in 425081ms.

Cause

預設的 maxBulkSize 為 50，會導致探索逾時錯誤。

 

Resolution

在產生此知識文章的事件中，降低 maxBulkSize 值可清除探索問題。
將 maxBulkSize 值設定為較小的數字，例如 15。
