NVP FLR 掛接作業或即時復原失敗,並出現下列錯誤:

執行還原時,此錯誤訊息會出現在 NetWorker Management Console (NMC) 復原精靈中。您也可以在復原記錄中找到此資訊:
對於 FLR:
NetWorker 伺服器:
- Linux:/nsr/logs/adhoc/nsrvproxy_flr/jobid。記錄
- Windows:C:\Program Files\EMC NetWorker\nsr\logs\adhoc\nsrvproxy_flr\jobid.log
vProxy:
- 作業正在主動執行:/opt/emc/vproxy/runtime/logs/vflrd/mount-SESSION-ID.log
- 以前(已完成)工作:/opt/emc/vproxy/runtime/logs/recycle/vflrd/DATE/mount-SESSION-ID.log
針對即時復原:
NetWorker 伺服器:
- Linux:/NSR/LOGS/RECOVER/RECOVER-SESSION-NAME。記錄
- Windows:C:\Program Files\EMC NetWorker\nsr\logs\recover\RECOVER-SESSION-NAME。記錄
vProxy: /opt/emc/vproxy/runtime/logs/recycle/vrecoverd/DATE/InstantRecover-SESSION-ID.log
Cause
Data Domain 上的 REST 服務已停用。
sysadmin@ddve01# adminaccess show
Service Enabled Allowed Hosts
----------- ------- -------------
ssh yes -
scp yes (same as ssh)
telnet no -
ftp no -
ftps no -
http no -
https yes -
web-service no N/A
----------- ------- -------------
在 FLR 或即時存取復原期間,vProxy 裝置會連線至 Data Domain,並使用 Data Domain 系統管理員帳戶進行驗證。此程序是建立 FLR 和即時復原程序所需的網路檔案系統 (NFS) 資料存放區所必需。當 Data Domain 上的 REST 服務停用時,vProxy 裝置無法與 DD 進行驗證,且無法建立 NFS 資料存放區。
Resolution
- 為 Data Domain 開啟 SSH 工作階段,並以「sysadmin」身分登入。
- 啟用 Web 服務:
adminaccess enable web-service - 驗證 Web 服務現在是否顯示為已啟用:
adminaccess show - 執行 VM 復原
