  • If the system is in production and under service I would recommend to open a support case.

     

    Do you see the same issue, if you try to boot the unit from another slot?

     

    I guess the whole system was migrated to the logical volume manager (LVM) already, right?

     

    If you can boot successfully from another volume you can try to delete the affected slot and re-install it.

     

  • Hi Sosabsd! I am having the same problem here with an F5 BIG IP BIGIP LTM 6400. Have you found any solution for this issue? Thanks.

     

  • i think you had better open a support case as Stephan suggested.
