DCX Switch blades in inhibited state.

  • 1.  DCX Switch blades in inhibited state.

    Posted 10-15-2014 05:49 AM

    Hi all!

     

    I have a Brocade DCX Backbone Director that have 4 Logical switchs, witch 4 Blades Switch (slot 3,4,9 and 10).

    In the 9 and 10 blades, have a conection between an Oracle Rac running on 4 blades Hitachi Symphony2000 with Linux RHEL 5.3, and a Oracle Database 10G in a USVP Hitachi Storage. 

    Suddenly, the database became inaccessible. We find that both Switch blades in Slots 9 and 10, wich are the ones that connect the DB witch the Hitachi Blades, were in state "inhibited". ( The switch yellow lights were lit sequentially from the bottom up)

    The solution was to do a dummy (remove and reinsert switches).

    The question is: what is the reason why the switches were inhibited? We find no record in the logs that indicate any error that causes this condition. Someone has had this experience and  can give me an idea of what can cause this condition?

    Thank you very much!

    Alexey, 

     

    I try to send two Supportsaves, but there is an error on the Page.

    I send you a Link to a google Drive, where there are 3 supportsave files. One ( supportsaveSDP7.tar[1].bz2) , extracted before the Dummy of the Switch blade on Slot 9, and two files ( floswfbocs1-postDummy.tar[1].bz2, supportsaveSDP7.tar[1].bz2)  extracted after de Dummy of the Switch blade of Slot 9.

    This Dummy was the solution of that issue.

    Hi,

     

    Once you've found the cause for this behavior, please, share it with the rest of the community 'cause I personally had never seen that error.

    Cesar,

     

    --->>>The question is: what is the reason why the switches were inhibited?

     

    I think, this error is caused due a Frame Collision caused by send/data transport from Hitachi Blade Switch to DCX, beetwen the same blade.

     

    i would suggest if the error persist, to open a call with Brocade or Hitachi.

     

    additional I would check if yboth DCX and Hitachi Blade Switch, have compatible FOS release.
