Question on integration of GTM & LTM

Hello all   Please forgive the multitude of amateurish questions. Just need to clear some things up in my head.   We have two GTMs on or network across two data centres. We also have some LTMs ...

Delvin,

you need to run big3d_install and bigip_add on GTM. When you run both the commands you need to give self ip address of both LTM(if it's in HA group).

you can found the big3d version using /shared/bin/big3d -v & /usr/sbin/big3d -v and it won't have any issues if we are installing big3d.

from http://support.f5.com/kb/en-us/solutions/public/13000/700/sol13703.html big3d installation behavior

The big3d process initiates and runs as follows on BIG-IP and Enterprise Manager devices:

The default big3d process is located in the /usr/sbin directory
At start up, the BIG-IP system verifies whether the /shared/bin/big3d process exists

    If the /shared/bin/big3d process exists and has an older modification time than the /usr/sbin/big3d process, the system copies the /usr/sbin/big3d process to the /shared/bin directory and runs the /shared/bin/big3d process
    If the /shared/bin/big3d process does not exist, the system copies the /usr/sbin/big3d process to the /shared/bin directory and runs the /shared/bin/big3d process

The result should be that the BIG-IP system runs the newer version of the big3d process from the /shared/bin directory. However, under certain conditions, the big3d process in the /shared/bin directory may be a different version than the instance in the /usr/sbin directory. For example, this may occur if an Enterprise Manager device pushes an older version of the big3d process to the system. To verify that the big3d version in the /shared/bin and /usr/sbin directories is the same, perform the following procedure:

Log in to the command line.
To verify the big3d version in the /shared/bin directory, type the following command:

/shared/bin/big3d -v
To verify the big3d version in the /usr/sbin directory, type the following command:

/usr/sbin/big3d -v
If the /shared/bin/big3d process is older, copy the newer big3d process to the /shared/bin/ directory.

For example, you would type the following command:

bigstart stop big3d && cp -a $(which big3d) /shared/bin/ && bigstart start big3d
