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
Connector  0A Not present
Connector  1A Not present
Connector  2A Present <-> Switch Port 24 is up (Enabled)
Connector  3A Not present
Connector  4A Not present
Connector  5A Present <-> Switch Port 30 is up (Enabled)
Connector  6A Not present
Connector  7A Not present
Connector  8A Present <-> Switch Port 31 is up (Enabled)
Connector  9A Present <-> Switch Port 14 is up (Enabled)
Connector 10A Present <-> Switch Port 16 is up (Enabled)
Connector 11A Present <-> Switch Port 18 is up (Enabled)
Connector 12A Not present
Connector 13A Not present
Connector 14A Not present
Connector 15A Not present
Connector 16A Not present
Connector 17A Not present
Connector  0B Not present
Connector  1B Present <-> Switch Port 21 is up (Enabled)
Connector  2B Not present
Connector  3B Not present
Connector  4B Present <-> Switch Port 27 is up (Enabled)
Connector  5B Present <-> Switch Port 29 is up (Enabled)
Connector  6B Present <-> Switch Port 36 is down (AutomaticHighErrorRate)
Connector  7B Not present
Connector  8B Not present
Connector  9B Present <-> Switch Port 13 is up (Enabled)
Connector 10B Present <-> Switch Port 15 is up (Enabled)
Connector 11B Present <-> Switch Port 17 is up (Enabled)
Connector 12B Not present
Connector 13B Not present
Connector 14B Not present
Connector 15B Not present
Connector 16B Not present
Connector 17B Not present

 

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
LinkWidthEnabled:................1X or 4X
LinkWidthSupported:..............1X or 4X
LinkWidthActive:.................4X
LinkSpeedSupported:..............2.5 Gbps or 5.0 Gbps or 10.0 Gbps
LinkState:.......................Down
PhysLinkState:...................Polling
LinkSpeedActive:.................2.5 Gbps
LinkSpeedEnabled:................2.5 Gbps or 5.0 Gbps or 10.0 Gbps
NeighborMTU:.....................2048
OperVLs:.........................VL0-7

Bir müddet bekledikten sonra listlinkup komutu ile kontrol ettiğinizde ilgili port Up ve Enabled durumda olacaktır.
