Starting LLT, GAB, and VCS after manual configuration
After you have configured LLT, GAB, and VCS, use the following procedures to start LLT, GAB, and VCS.
- On each node, run the following command to start LLT:
# /etc/init.d/llt.rc start
If LLT is configured correctly on each node, the console output resembles:
Loading LLT Driver... Starting LLT: LLT: loading module... Loaded kernel_version on kernel kernel_version LLT: configuring module where, kernel_version is the kernel version of the Linux operating system
- On each node, run the following command to verify that LLT is running:
# /sbin/lltconfig LLT is running
- On each node, run the following command to start GAB:
# /etc/init.d/gab.rc start
If GAB is configured correctly on each node, the console output resembles:
GAB: Starting GAB: Starting Done
- On each node, run the following command to verify that GAB is running:
# /sbin/gabconfig -a GAB Port Memberships =================================== Port a gen a36e0003 membership 01
