Symptoms
NWUI 解決方案正用於管理 NetWorker 資料區域。導航面板用於選擇“保護>組”,詳細資訊窗格將生成”Failed to get the list of groups. Unable to parse 'disk_uuid' string: '50301dd2-9032-1b04-eca2-c943c61fd55d.'「VMware 保護群組已設定使用標籤來選取受保護虛擬機器 (VM) 的規則,且參照的 VM 具有磁碟排除項目。

Cause
VMware 保護群組具有排除的 .vmdk 磁碟的 VM null 項目。在擷取保護群組資訊時,空的 .vmdk 磁碟項目會導致 RESTAPI 失敗。VMware 保護群組資源中的 null 項目顯示為退格鍵和引號 (\“\”)。以下是 VMware 保護群組中的 null 項目範例:
{\"moref-id\":\"vm-1024536\",\"uuid\":\"50301dd2-9032-1b04-eca2-c943c61fd55d\",\"type\":\"VMDisk\",\"disks\":[\"\",\"6000C292-524d-1baa-f10b-5e780833a1ed\",\"6000C29c-75b5-ad1f-27d3-602b6d5da260\"]}
null 條目的原因未知。
Resolution
使用 NetWorker 系統管理程式 (nsradmin) 從 NetWorker 資源資料庫 (nsrdb) 移除 null 的 .vmdk 磁碟項目。
- 執行伺服器保護備份工作,並確定已取得引導備份:
mminfo -B
- 在 NetWorker 伺服器上建立 nsrdb 目錄的複本。
- Linux:
/nsr/res/nsrdb - Windows:
C:\Program Files\EMC NetWorker\nsr\res\nsrdb
3.從命令列或 Linux Shell 開啟 nsradmin 命令列公用程式,並輸入以下內容以存取視覺化模式 visual。這會載入互動式命令列公用程式,您可以從中瀏覽和修改 NetWorker 資源:
nsradmin > visual mode > NSR Protection Group > Select the "NSR Protection Group" > Edit > delete the NULL Disk entry in the "vproxy group exclude items" > save > Exit
以前:
{\"moref-id\":\"vm-1024536\",\"uuid\":\"50301dd2-9032-1b04-eca2-c943c61fd55d\",\"type\":\"VMDisk\",\"disks\":[\"\",\"6000C292-524d-1baa-f10b-5e780833a1ed\",\"6000C29c-75b5-ad1f-27d3-602b6d5da260\"]}
後:
{\"moref-id\":\"vm-1024536\",\"uuid\":\"50301dd2-9032-1b04-eca2-c943c61fd55d\",\"type\":\"VMDisk\",\"disks\":[\"6000C292-524d-1baa-f10b-5e780833a1ed\",\"6000C29c-75b5-ad1f-27d3-602b6d5da260\"]}
如果發現任何問題,您可以還原到在應用更改之前創建的 nsrdb 副本。
