Depois de substituir o hardware e atribuir discos, você deve excluir plexes remotos com falha que são de propriedade dos nós do local sobreviventes, mas localizados no local de desastre.
Estas etapas são executadas no cluster sobrevivente.

Identificar os plexes remotos com falha:
storage aggregate plex showO exemplo a seguir chama os plexes que são remotos (não plex0) e têm um status de "failed" (Falha):
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::>

Fique offline cada um dos plexes com falha e, em seguida, exclua-os:
-
Fique offline os plexes com falha:
storage aggregate plex offline -aggregate aggregate-name -plex plex-idO exemplo a seguir mostra o agregado "node_B_2_aggr1/plex1" sendo colocado offline:
cluster_B::> storage aggregate plex offline -aggregate node_B_1_aggr0 -plex plex4 Plex offline successful on plex: node_B_1_aggr0/plex4
-
Eliminar o Plex com falha:
storage aggregate plex delete -aggregate aggregate-name -plex plex-idVocê pode destruir o Plex quando solicitado.
O exemplo a seguir mostra o Plex node_B_2_aggr1/plex1 sendo excluído.
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::>
Você deve repetir estas etapas para cada um dos plexos com falha.

Identificar os agregados comutados:
storage aggregate show -is-home falseVocê também pode usar o
storage aggregate plex show -fields aggregate,status,is-online,plex,poolcomando para identificar agregados comutados do Plex 0. Eles terão um status de "falhou, inativo".Os comandos a seguir mostram quatro agregados comutados:
-
node_A_1_aggr1
-
node_A_1_aggr2
-
node_A_2_aggr1
-
node_A_2_aggr2

Identificar plexos comutados:
storage aggregate plex show -fields aggregate,status,is-online,Plex,poolVocê deseja identificar os plexes com um status de "falhou, inativo".
Os comandos a seguir mostram quatro agregados comutados:

Eliminar o Plex com falha:
storage aggregate plex delete -aggregate node_A_1_aggr1 -plex plex0Você pode destruir o Plex quando solicitado.
O exemplo a seguir mostra o nó Plex_A_1_aggr1/plex0 sendo excluído:
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::>Você deve repetir essas etapas para cada um dos agregados com falha.

Verifique se não há plexo com falha restante no local sobrevivente.
A saída a seguir mostra que todos os plexes são normais, ativos e online.
