在更換硬體並指派磁碟之後、您必須刪除故障的遠端叢集、這些叢集由存續的站台節點擁有、但位於災難站台。
關於這項工作
這些步驟會在正常運作的叢集上執行。
步驟
-
識別本機Aggregate：「torage gregate show -is home-true」
cluster_B::> storage aggregate show -is-home true cluster_B Aggregates: Aggregate Size Available Used% State #Vols Nodes RAID Status --------- -------- --------- ----- ------- ------ ---------------- ------------ node_B_1_aggr0 1.49TB 74.12GB 95% online 1 node_B_1 raid4, mirror degraded node_B_2_aggr0 1.49TB 74.12GB 95% online 1 node_B_2 raid4, mirror degraded node_B_1_aggr1 2.99TB 2.88TB 3% online 15 node_B_1 raid_dp, mirror degraded node_B_1_aggr2 2.99TB 2.91TB 3% online 14 node_B_1 raid_tec, mirror degraded node_B_2_aggr1 2.95TB 2.80TB 5% online 37 node_B_2 raid_dp, mirror degraded node_B_2_aggr2 2.99TB 2.87TB 4% online 35 node_B_2 raid_tec, mirror degraded 6 entries were displayed. cluster_B::> -
識別故障的遠端程序：
「集合體展示」
下列範例會呼叫遠端（非plex0）且狀態為「失敗」的叢集：
cluster_B::> storage aggregate plex show -fields aggregate,status,is-online,Plex,pool aggregate plex status is-online pool ------------ ----- ------------- --------- ---- node_B_1_aggr0 plex0 normal,active true 0 node_B_1_aggr0 plex4 failed,inactive false - <<<<---Plex at remote site node_B_2_aggr0 plex0 normal,active true 0 node_B_2_aggr0 plex4 failed,inactive false - <<<<---Plex at remote site node_B_1_aggr1 plex0 normal,active true 0 node_B_1_aggr1 plex4 failed,inactive false - <<<<---Plex at remote site node_B_1_aggr2 plex0 normal,active true 0 node_B_1_aggr2 plex1 failed,inactive false - <<<<---Plex at remote site node_B_2_aggr1 plex0 normal,active true 0 node_B_2_aggr1 plex4 failed,inactive false - <<<<---Plex at remote site node_B_2_aggr2 plex0 normal,active true 0 node_B_2_aggr2 plex1 failed,inactive false - <<<<---Plex at remote site node_A_1_aggr1 plex0 failed,inactive false - node_A_1_aggr1 plex4 normal,active true 1 node_A_1_aggr2 plex0 failed,inactive false - node_A_1_aggr2 plex1 normal,active true 1 node_A_2_aggr1 plex0 failed,inactive false - node_A_2_aggr1 plex4 normal,active true 1 node_A_2_aggr2 plex0 failed,inactive false - node_A_2_aggr2 plex1 normal,active true 1 20 entries were displayed. cluster_B::>

將每個失敗的叢體離線、然後刪除：
-
使故障的叢體離線：
「torage aggregate plex offline -aggregate aggreg-name -plex」
下列範例顯示正在離線的Aggregate "node_B_2_aggr1/plex1"：
cluster_B::> storage aggregate plex offline -aggregate node_B_1_aggr0 -plex plex4 Plex offline successful on plex: node_B_1_aggr0/plex4
-
刪除故障叢：
「torage Aggregate plex刪除-Aggregate aggreg-name -plex id」
出現提示時、您可以銷毀叢。
下列範例顯示要刪除的叢節點_B_2_aggr1/plex1。
cluster_B::> storage aggregate plex delete -aggregate node_B_1_aggr0 -plex plex4 Warning: Aggregate "node_B_1_aggr0" is being used for the local management root volume or HA partner management root volume, or has been marked as the aggregate to be used for the management root volume after a reboot operation. Deleting plex "plex4" for this aggregate could lead to unavailability of the root volume after a disaster recovery procedure. Use the "storage aggregate show -fields has-mroot,has-partner-mroot,root" command to view such aggregates. Warning: Deleting plex "plex4" of mirrored aggregate "node_B_1_aggr0" on node "node_B_1" in a MetroCluster configuration will disable its synchronous disaster recovery protection. Are you sure you want to destroy this plex? {y|n}: y [Job 633] Job succeeded: DONE cluster_B::>
您必須針對每個失敗的叢體重複這些步驟。

確認系統已移除該複本：
「torage Aggregate plex show -功能 變數aggregate、STATUS、is - online、plex、pool」
cluster_B::> storage aggregate plex show -fields aggregate,status,is-online,Plex,pool aggregate plex status is-online pool ------------ ----- ------------- --------- ---- node_B_1_aggr0 plex0 normal,active true 0 node_B_2_aggr0 plex0 normal,active true 0 node_B_1_aggr1 plex0 normal,active true 0 node_B_1_aggr2 plex0 normal,active true 0 node_B_2_aggr1 plex0 normal,active true 0 node_B_2_aggr2 plex0 normal,active true 0 node_A_1_aggr1 plex0 failed,inactive false - node_A_1_aggr1 plex4 normal,active true 1 node_A_1_aggr2 plex0 failed,inactive false - node_A_1_aggr2 plex1 normal,active true 1 node_A_2_aggr1 plex0 failed,inactive false - node_A_2_aggr1 plex4 normal,active true 1 node_A_2_aggr2 plex0 failed,inactive false - node_A_2_aggr2 plex1 normal,active true 1 14 entries were displayed. cluster_B::>

識別切換式集合體：
「torage Aggregate show -is home-false」
您也可以使用「叢集Aggregate show -Fields Aggregate、STATUS、is - online、plex、pool」命令來識別叢0交換式Aggregate。它們的狀態為「失敗、非作用中」。
下列命令顯示四個切換式Aggregate：
-
node_a_1_aggr1
-
node_a_1_aggr2
-
node_a_2_aggr1
-
node_a_2_aggr2

識別交換式多工模式：
「torage aggregate plex show -功能 變數aggregate、STATUS、is - online、Plex、Pool」
您想要識別狀態為「失敗、非作用中」的叢集。
下列命令顯示四個切換式Aggregate：
cluster_B::> storage aggregate plex show -fields aggregate,status,is-online,Plex,pool aggregate plex status is-online pool ------------ ----- ------------- --------- ---- node_B_1_aggr0 plex0 normal,active true 0 node_B_2_aggr0 plex0 normal,active true 0 node_B_1_aggr1 plex0 normal,active true 0 node_B_1_aggr2 plex0 normal,active true 0 node_B_2_aggr1 plex0 normal,active true 0 node_B_2_aggr2 plex0 normal,active true 0 node_A_1_aggr1 plex0 failed,inactive false - <<<<-- Switched over aggr/Plex0 node_A_1_aggr1 plex4 normal,active true 1 node_A_1_aggr2 plex0 failed,inactive false - <<<<-- Switched over aggr/Plex0 node_A_1_aggr2 plex1 normal,active true 1 node_A_2_aggr1 plex0 failed,inactive false - <<<<-- Switched over aggr/Plex0 node_A_2_aggr1 plex4 normal,active true 1 node_A_2_aggr2 plex0 failed,inactive false - <<<<-- Switched over aggr/Plex0 node_A_2_aggr2 plex1 normal,active true 1 14 entries were displayed. cluster_B::>

刪除故障叢：
「torage Aggregate plex DELETE -Aggregate node_a_aggr1 -plex plex0」
出現提示時、您可以銷毀叢。
下列範例顯示要刪除的叢節點_a_aggr1/plex0：
cluster_B::> storage aggregate plex delete -aggregate node_A_1_aggr1 -plex plex0 Warning: Aggregate "node_A_1_aggr1" hosts MetroCluster metadata volume "MDV_CRS_e8457659b8a711e78b3b00a0988fe74b_A". Deleting plex "plex0" for this aggregate can lead to the failure of configuration replication across the two DR sites. Use the "volume show -vserver <admin-vserver> -volume MDV_CRS*" command to verify the location of such volumes. Warning: Deleting plex "plex0" of mirrored aggregate "node_A_1_aggr1" on node "node_A_1" in a MetroCluster configuration will disable its synchronous disaster recovery protection. Are you sure you want to destroy this plex? {y|n}: y [Job 639] Job succeeded: DONE cluster_B::>您必須針對每個故障的集合體重複這些步驟。

確認在正常運作的站台上沒有剩餘的失敗plexes。
下列輸出顯示所有的plexes都是正常、作用中和線上的。
