Dell Unity:區塊匯入工作階段中出現無法復原的錯誤
Summary: 若要針對 Unisphere 中失敗的區塊匯入工作階段進行故障診斷,請使用 UEMCLI 檢視失敗工作階段的詳細資訊。Unisphere (UI) 可能無法提供解決問題的足夠資訊。

x Import_FNM00104600114_migrate_xxx Error block
將滑鼠停留在上述錯誤的紅色 X 上會顯示更多詳細資訊:
"The import session failed due to a non-recoverable error. Go to session properties dialog to check health details and resolution steps in GUI or use UEMCLI command import/session/element show -detail to check session health details and resolution steps."
工作階段詳細資料的 UEMCLI 輸出會顯示類似的訊息:
spa:~>uemcli /import/session show -detail
1: ID = import_65548
Name = Import_ABCD1234567890_101_20160915160406.767527+000
Session type = block
Health state = Critical failure (25)
Health details = "The import session failed due to a non-recoverable error. For Block import session non-recoverable error details, check session element's health details and resolution steps."
State = Error ---output abridged----
上述匯入工作階段 ID 的工作階段元素的 UEMCLI 輸出詳細資訊:
範例 1:
spa:~>uemcli /import/session/element -importId import_65548 show -detail
1: Source system = RS_65560
Source resource = LUN 101
Target resource = sv_11
Health state = Major failure (20)
Health details = "Element import session related Sancopy session ran into error: 0x712A8021: The destination device could not be found. This is probably due to incorrect zoning on the switch or the device is not in the correct storage group. (WWN). This can be due to FC Zoning or iSCSI Connection configuration between VNX and Unity arrays. Please follow documentation to configure connectivity between all SP pairs between VNX and Unity system. Once FC/iSCSI connection configuration is validated, please run 'Verify and Update' operation for Remote System connection to VNX to discover/update all configuration changes. Then issue resume operation on the import session to recover session from error state."
範例 2:
spb:~> uemcli /import/session/element -importId import_65600 show -detail
2: Source system = RS_65596
Source resource = block_1
Target resource = sv_79
Health state = Critical failure (25)
Health details = "The import session failed due to a non-recoverable failure. Cancel the import session and determine the integrity of the data."Cause
A "Non-recoverable error" 在塊導入會話中可能有多種原因,並且可能並不總是永久性的。檢查元素詳細資訊有助於確定問題的根本原因。可能的原因包括:
- iSCSI 連線能力問題,此問題可以解決,並允許工作階段重新開機
- 來源 VNX 陣列上的問題,例如一致性群組中遺失 LUN,這可能需要取消工作階段
- 由於 Unity 陣列上刪除或缺乏更新,導致來源 LUN 無法使用,這也需要取消工作階段
調查元素詳細資訊有助於確定原因並採取適當的措施來解決或取消失敗的工作階段。
Resolution
如上所述,可能有不同的問題導致 'Non-recoverable error' 的區塊匯入工作階段。
Unisphere (UI) 可能無法提供解決問題的足夠詳細資料。建議使用 UEMCLI 工作階段元素的輸出,以進行故障診斷並解決問題。
匯入工作階段失敗,並顯示「無法復原的錯誤」:
1.從 UEMCLI 中,判斷匯入工作階段 ID:
spb:~> uemcli /import/session/block show -detail
1: ID = import_65600
Name = Import_ABCD1234567890_migrate_20161027142745.428999+000
Session type = block
Health state = Critical failure (25)
2.檢視匯入工作階段 ID 的匯入工作階段元素的詳細資料:
spb:~> uemcli /import/session/element -importId import_65600 show -detail
1: Source system = RS_65596
Source resource = block_1
Target resource = sv_79
Health state = Critical failure (25)
Health details = "The import session failed due to a non-recoverable failure. Cancel the import session and determine the integrity of the data."
3.請遵循「健全狀況詳細資料」輸出內容中提供的建議,進行故障診斷並解決匯入工作階段問題。
便條:若要繼續,請在 UI 的 「更多動作」 下繼續工作階段。
