以ONTAP 靜態IP組態開機至更換的控制器模組MetroCluster
您必須將災難現場的替換節點開機至ONTAP 該作業系統。
這項工作從災難站台的節點開始、以維護模式執行。
-
在其中一個替換節點上、結束以顯示載入程式提示:「halt(停止)」
-
顯示開機功能表:「boot_ONTAP功能表」
-
從開機功能表中、選取選項6 *從備份組態更新Flash *。
系統開機兩次。當系統提示您繼續時、您應該回應「是」。第二次開機之後、當系統ID不符時、您應該回應「y」。
如果未清除已用過的更換控制器模組的NVRAM內容、您可能會看到下列緊急訊息:「嚴重:NVRAM內容無效…」 如果發生這種情況、ONTAP 請再次將系統開機至更新提示字元(「boot_ONTAP功能表」)。然後您就需要 重設boot_recovery和RDB_rebootargs -
確認以繼續提示:
Selection (1-9)? 6 This will replace all flash-based configuration with the last backup to disks. Are you sure you want to continue?: yes
-
系統ID不相符提示:
WARNING: System ID mismatch. This usually occurs when replacing a boot device or NVRAM cards! Override system ID? {y|n} y
-
-
從存續站台、確認已將正確的合作夥伴系統ID套用至節點:
「MetroCluster 這個節點顯示欄位節點系統ID、ha-合作 夥伴系統ID、dr-Partner SystemID、dr輔助系統ID」
在此範例中、輸出中應該會出現下列新的系統ID:
-
節點_a_1:1574774970
-
節點_a_2:1574774991
「ha-合作 夥伴系統ID」欄應顯示新的系統ID。
metrocluster node show -fields node-systemid,ha-partner-systemid,dr-partner-systemid,dr-auxiliary-systemid dr-group-id cluster node node-systemid ha-partner-systemid dr-partner-systemid dr-auxiliary-systemid ----------- ---------- -------- ------------- ------ ------------ ------ ------------ ------ -------------- 1 Cluster_A Node_A_1 1574774970 1574774991 4068741254 4068741256 1 Cluster_A Node_A_2 1574774991 1574774970 4068741256 4068741254 1 Cluster_B Node_B_1 - - - - 1 Cluster_B Node_B_2 - - - - 4 entries were displayed.
-
-
如果合作夥伴系統ID設定不正確、您必須手動設定正確的值:
-
停止並在節點上顯示載入程式提示。
-
驗證合作夥伴sysid bootag的目前值:
《王子》
-
將值設為正確的合作夥伴系統ID:
「etenv合作夥伴sysid合作夥伴sysid」
-
開機節點:
Boot_ONTAP
-
如有必要、請在其他節點上重複這些子步驟。
-
-
確認災難站台的替換節點已準備好進行切換:
「不一樣的秀」MetroCluster
替換節點應處於等待切換回復模式。如果它們處於正常模式、您可以重新啟動替換節點。開機之後、節點應處於等待切換回復模式的狀態。
下列範例顯示替換節點已準備好進行切換:
cluster_B::> metrocluster node show DR Configuration DR Group Cluster Node State Mirroring Mode ----- ------- ------------------ -------------- --------- -------------------- 1 cluster_B node_B_1 configured enabled switchover completed node_B_2 configured enabled switchover completed cluster_A node_A_1 configured enabled waiting for switchback recovery node_A_2 configured enabled waiting for switchback recovery 4 entries were displayed. cluster_B::>
-
驗MetroCluster 證「不中斷連線」組態設定:
「組態設定連線顯示」MetroCluster
組態狀態應顯示為「已完成」。

-
在災難站台的其他節點上重複上述步驟。
[Reset-the_boot-recovery ]重設boot_recovery和RDB_rebootargs
如果需要、您可以重設boot_recovery和RDB_reboot_bootargs
-
將節點停止回載入程式提示:
node_A_1::*> halt -node _node-name_
-
檢查是否已設定下列bootargs:
LOADER> printenv bootarg.init.boot_recovery LOADER> printenv bootarg.rdb_corrupt
-
如果其中任一bootarg已設定為值、請將其取消設定並啟動ONTAP
LOADER> unsetenv bootarg.init.boot_recovery LOADER> unsetenv bootarg.rdb_corrupt LOADER> saveenv LOADER> bye
