Upgrade to the Latest D7 Release

It is always recommended to upgrade to the latest D7 release.

Reboot D7 and Reinstall the Drivers

1. Stop D7:
   ebs_stop
2. Remove the drivers:
   $EBSHOME/access/install/ebs_modremove –f
3. Reboot the node:
   reboot
4. Install the drivers:
   $EBSHOME/access/install/ebs_modinstall –f
5. Reboot the node:
   reboot
6. Start D7:
   ebs_start

Replace the Card

Please try to replace the card with a working one from another node. If this does not work, please try to replace the complete module on which the card is installed.

Contact Support

If the described solutions did not help, please submit a request on the Skyvera Support portal, providing the following details:

• The output of the hat_collect script.
• Capture the details from the card by running the following commands as the root user:
  
  
  1. cd $EBSHOME/access/bin
  2. getcfg
     
     Sample output:
     

      Driver    Board Type   Slot   Instance
      ------     ----------      ----    --------
      adaxm   HDCX             0           0
      adaxm   HDCX             1           1

      

• Collect the qcxtest data. Below you will find a sample with outputs for the card 0 (the commands are highlighted in bold).
