影響
SDC 可能無法存取其磁碟區。
Cause
SDS 已新增至現有叢集。在這種情況下,每個現有的 SDS 都配置了 4 個 IP 並使用 IP 角色。新的 SDS 僅以一個 IP 加入。在這種情況下,IP 位於僅限 SDS 至 SDS 的子網路上。這可讓儲存集區將資料遷移至此 SDS。SDC 取得新的資料對應後,SDC 會嘗試連線至此 SDS,但 SDS 沒有設定的 IP 以允許任何 SDC 連線。SDC 無法存取 SDS。
在 MDM 事件記錄中,我們可以看到新增 SDS 時只配置了一個 IP:
2020-04-08 11:14:57.251 MDM_CLI_CONF_COMMAND_RECEIVED INFO Command add_sds received, User: 'admin'. [4574194] protection_domain pdX fault_set N/A New SDS name: sdsX Hostname: 172.17.16.38 Port: 7072
Resolution
錯誤地將 SDS 新增至現有叢集後,您可以將額外的 IP 新增至 SDS 組態
將 SDS 新增至現有叢集時,最佳實務是新增所有 IP 並使用正確的 IP 角色加以設定。
