更换硬件并分配磁盘后，您必须删除故障远程丛，这些丛属于运行正常的站点节点，但位于灾难站点上。
关于此任务
这些步骤将在运行正常的集群上执行。
步骤
-
确定本地聚合：
storage aggregate show -is-home truecluster_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::> -
确定发生故障的远程丛：
storage aggregate plex show以下示例将调用处于远程状态（而不是 plex0 ）且状态为 "Failed" 的丛：
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::>

使每个故障丛脱机，然后将其删除：
-
使故障丛脱机：
storage aggregate plex offline -aggregate aggregate-name -plex plex-id以下示例显示了正在脱机的聚合 "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
-
删除故障丛：
storage aggregate plex delete -aggregate aggregate-name -plex plex-id出现提示时，您可以销毁丛。
以下示例显示了要删除的丛 node_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::>
您必须对每个故障丛重复这些步骤。

确定已切换的聚合：
storage aggregate show -is-home false您还可以使用
storage aggregate plex show -fields aggregate ， status ， is-online ， plex ， pool命令来标识丛 0 已切换聚合。它们的状态将为 " 失败，非活动 " 。以下命令显示了四个已切换的聚合：
-
node_A_1_aggr1
-
node_A_1_aggr2
-
node_A_2_aggr1
-
node_A_2_aggr2.

识别已切换的丛：
storage aggregate plex show -fields aggregate ， status ， is-online ， Plex ， pool您希望确定状态为 " 失败，非活动 " 的丛。

删除故障丛：
storage aggregate plex delete -aggregate node_A_1_aggr1 -plex plex0出现提示时，您可以销毁丛。
以下示例显示了要删除的丛 node_A_1_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::>您必须对每个故障聚合重复这些步骤。

验证运行正常的站点上是否没有剩余出现故障的丛。
以下输出显示所有丛均为正常，活动和联机。
