Oracle Exadata infiniband switch portları AutomaticHighErrorRate sebebiyle down olduğunda nasıl up yapılır ?

Oracle Exadata infiniband switch portlarındaki hata sayısı belirtilen eşik değerlere ulaştığında otomatik olarak AutomaticHighErrorRate olacak şekilde down duruma getirilmektedir. Sorun giderildikten sonra aşağıdaki şekilde up duruma getirilebilir.

Öncelikle sorun olan infiniband switch’e ssh ile bağlanılmalıdır.

Down durumdaki portun tespiti :

[root@exasw-iba01 ~]# listlinkup

Yukardaki çıktıdan görüldüğü üzere 36 numaralı port down durumdadır. Bu portu aşağıdaki şekilde up duruma getirebilirsiniz.

[root@exasw-iba01 ~]# enableswitchport --automatic Switch 36
Enable connector 6B Switch port 36
Adminstate:......................Enabled
