Cause
This is due to auto-load functionality in Solaris, when any script/code tries to access the device file, the OS will load the corresponding module in the kernel. For a one-node VCS cluster, LLT and GAB are not required and hence disabled in VCS default configuration files (/etc/default/llt and /etc/default/gab).
Resolution
We should remove the LGF drivers so that modules will not get auto-loaded during bootup. This is typically applicable for single node clusters.
Remove the driver using following command:
# rem_drv
If some more nodes are to be added in this cluster, then we will have to add the LGF drivers back and enable LGF services so that LGF services can start after reboot.
To add the driver back, use this command:
# add_drv
Currently removal/addition of drivers will have to be done manually. This is planned to be fixed in the next major release of VCS.
Note:
Additional steps may be needed to convert this cluster from single node cluster to multi-node cluster.

Solaris 10
