Enabling LLT, GAB, and I/O fencing
Complete the following procedures to enable the kernel modules.
To enable LLT:
- In the
/etc/default/llt file, ensure LLT_START=1.
- Create
llt.odm in any directory with the following text:Config_Rules:
phase = 2
seq = 21
rule = "/etc/methods/loadllt"
- Run the following commands with the file path.
# odmadd $DIR/llt.odm
# /etc/methods/loadllt
To enable GAB:
- In the
/etc/default/gab file, ensure GAB_START=1.
- Run the following commands:
# /usr/sbin/slibclean
# /usr/bin/odmadd /usr/lib/methods/gab.odm
# /etc/methods/gabkext -start
To enable I/O fencing:
- In the
/etc/default/vxfen file, ensure VXFEN_START=1.
- Run the following commands:
# /usr/sbin/slibclean
# /usr/bin/odmadd /usr/lib/methods/vxfen.odm
# /usr/bin/odmadd /usr/lib/methods/vxfend.odm
# /etc/methods/vxfenext -start -dvxfen
# /etc/methods/vxfenext -start -dvxfend
- Reboot the nodes.
After enabling kernel modules, you can run the init scripts for each kernel module to start LLT, GAB, and I/O fencing
