out of band access for vCMP guest

im working with some vCMP guests on a vCMP host now. everything is working fine, but i was wondering how i would access a vCMP guest out of band when it gets in a reboot loop or doesnt want to boot or such. the serial access only seems to work for the vCMP host, am i missing something or ...?

 

  • Hi Boneyard,

     

     

    You can use a virtual console (vconsole) for this:

     

     

     

    Manual Chapter: Working with vCMP Guests

     

    https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/vcmp-admin-11-2-0/7.html

     

     

    Accessing a vCMP guest using the vconsole utility

     

    Before accessing a vCMP guest, verify that you have configured at least one self IP address on the guest.

     

    You can access an individual VM of a guest after you have created the guest. Console access is available only for guests whose network mode is Isolated.

     

    Note: When you reboot the guest from within the vconsole utility, the BIG-IP system terminates your connection to the guest. You can access the guest again when the reboot operation is finished.

     

     

    From a system on the external network, open a serial console utility.

     

    In the utility, type the management IP address of the vCMP host. This displays a console window for logging in to the BIG-IP system.

     

    Using your user name and password credentials, log in to the BIG-IP system.

     

    From the command line prompt, use the telnet-based vconsole utility and specify a guest name (and for all-slot guests only, a slot number) to log in to a guest VM. You can do this at the system prompt or from within tmsh.

     

    Option Command sequence

     

    From the system prompt Type run util vconsole guest_name slot_number

     

    From the tmsh prompt Type vconsole guest_name slot_number

     

    Valid slot numbers are 1, 2, 3, and 4.

     

     

    You are now logged in to a guest VM.

  • hmmm, read that guide a couple of times the last few weeks, must have missed that part.

     

     

    works as a charm, thank you Aaron. I now also understand what all those 127.x.x.x address are for :)
