Suggerisci modifiche
PDF
Dopo la sostituzione dell'hardware e l'assegnazione dei dischi, è necessario eliminare i plessi remoti guasti di proprietà dei nodi del sito sopravvissuti ma che si trovano nel sito di emergenza.
Questi passaggi vengono eseguiti sul cluster esistente.

Identificare i plessi remoti guasti:
storage aggregate plex showNell'esempio riportato di seguito vengono indicati i plex remoti (non plex0) con stato "failed" (non riuscito):

Portare offline ciascuno dei plessi guasti, quindi eliminarli:
-
Take offline the failed plex:
storage aggregate plex offline -aggregate aggregate-name -plex plex-idL'esempio seguente mostra l'aggregato "Node_B_2_aggr1/plex1" che viene portato offline:
cluster_B::> storage aggregate plex offline -aggregate node_B_1_aggr0 -plex plex4 Plex offline successful on plex: node_B_1_aggr0/plex4
-
Eliminare il plesso guasto:
storage aggregate plex delete -aggregate aggregate-name -plex plex-idQuando richiesto, è possibile distruggere il plex.
Nell'esempio seguente viene mostrato il nodo plex_B_2_aggr1/plex1 cancellato.
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::>
È necessario ripetere questi passaggi per ciascuno dei plessi guasti.

Verificare che i plessi siano stati rimossi:

Identificare gli aggregati di switchover:
storage aggregate show -is-home falseÈ inoltre possibile utilizzare
storage aggregate plex show -fields aggregate,status,is-online,plex,poolcomando per identificare aggregati di switchover plex 0. Avranno lo stato "failed, inactive" (non riuscito, inattivo).I seguenti comandi mostrano quattro aggregati di switchover:
-
Node_A_1_aggr1
-
Node_A_1_aggr2
-
Node_A_2_aggr1
-
Node_A_2_aggr2

Identificare i plessi di switchover:
storage aggregate plex show -fields aggregate,status,is-online,Plex,poolSi desidera identificare i plessi con lo stato "failed, inactive" (non riuscito, inattivo).
I seguenti comandi mostrano quattro aggregati di switchover:

Eliminare il plesso guasto:
storage aggregate plex delete -aggregate node_A_1_aggr1 -plex plex0Quando richiesto, è possibile distruggere il plex.
Il seguente esempio mostra che il nodo plex_A_1_aggr1/plex0 è stato cancellato:
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::>È necessario ripetere questi passaggi per ciascuno degli aggregati guasti.

Verificare che non vi siano altri plex guasti sul sito sopravvissuto.
Il seguente output mostra che tutti i plessi sono normali, attivi e online.
