删除幸存站点拥有的故障丛（MetroCluster IP 配置）
更换硬件并分配磁盘后，必须删除由幸存站点节点所有但位于灾难站点的故障远程丛。
关于本任务
在幸存集群上执行这些步骤。
- 确定本地聚合：storage aggregate show -is-home true
示例
cluster_B::> storage aggregate show -is-home true

cluster_B::> - 确定发生故障的远程丛：storage aggregate plex show
示例
以下示例调出了状态为 failed 的远程丛（不是 plex0）：
cluster_B::> storage aggregate plex show -fields aggregate,status,is-online,Plex,pool
aggregate plex status is-online pool

cluster_B::> - 使每个发生故障丛脱机，然后删除它们：
- 使发生故障的丛脱机：storage aggregate plex offline -aggregate aggregate-name -plex plex-id
示例
以下示例显示正在使聚合 node_B_2_aggr1/plex1 脱机：
cluster_B::> storage aggregate plex offline -aggregate node_B_1_aggr0 -plex plex4
Plex offline successful on plex: node_B_1_aggr0/plex4 - 删除发生故障的丛：storage aggregate plex delete -aggregate aggregate-name -plex plex-id
在出现提示时可以销毁丛。
示例
以下示例显示正在删除丛 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

必须对每个发生故障的丛重复以上步骤。
- 使发生故障的丛脱机：storage aggregate plex offline -aggregate aggregate-name -plex plex-id
- 确认已删除丛：storage aggregate plex show -fields aggregate,status,is-online,plex,pool
示例
cluster_B::> storage aggregate plex show -fields aggregate,status,is-online,Plex,pool
aggregate plex status is-online pool

cluster_B::> - 确定已切换的聚合：storage aggregate show -is-home false
还可以使用 storage aggregate plex show -fields aggregate,status,is-online,plex,pool 命令确定丛 0 已切换的聚合。它们的状态为 failed, inactive。
示例
以下命令显示了四个已切换的聚合：
示例
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_B::> - 删除发生故障的丛：storage aggregate plex delete -aggregate node_A_1_aggr1 -plex plex0
在出现提示时可以销毁丛。
示例
以下示例显示正在删除丛 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
