刪除存續站台擁有的失敗叢集(MetroCluster 不適用的IP組態)

貢獻者

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。

這些步驟會在正常運作的叢集上執行。

步驟
  1. 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::>
  2. 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::>
  3. 將每個失敗的叢體離線、然後刪除:

    1. 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
    2. 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。

  4. 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::>
  5. 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

    cluster_B::> storage aggregate show -is-home false
    
    cluster_A Switched Over Aggregates:
    Aggregate     Size Available Used% State   #Vols  Nodes            RAID Status
    --------- -------- --------- ----- ------- ------ ---------------- ------------
    node_A_1_aggr1 2.12TB  1.88TB   11% online      91 node_B_1        raid_dp,
                                                                       mirror
                                                                       degraded
    node_A_1_aggr2 2.89TB  2.64TB    9% online      90 node_B_1        raid_tec,
                                                                       mirror
                                                                       degraded
    node_A_2_aggr1 2.12TB  1.86TB   12% online      91 node_B_2        raid_dp,
                                                                       mirror
                                                                       degraded
    node_A_2_aggr2 2.89TB  2.64TB    9% online      90 node_B_2        raid_tec,
                                                                       mirror
                                                                       degraded
    4 entries were displayed.
    
    cluster_B::>
  6. 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::>
  7. 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。

  8. 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。

    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_2_aggr2 plex0 normal,active true     0
    node_B_1_aggr1 plex0 normal,active true     0
    node_B_2_aggr2 plex0 normal,active true     0
    node_A_1_aggr1 plex4 normal,active true     1
    node_A_1_aggr2 plex1 normal,active true     1
    node_A_2_aggr1 plex4 normal,active true     1
    node_A_2_aggr2 plex1 normal,active true     1
    10 entries were displayed.
