Troubleshooting OpenSAF
======================
System Controller Checklist
===========================
1. If TIPC is chosen as the mds transport , did TIPC installation fail?
The following error "FATAL: Error inserting
tipc (<kernel_modules_dir>/tipc.ko): Invalid module format" indicates that
user had not compiled TIPC with proper kernel files. Compile TIPC with
appropriate kernel header files (e.g. They are different for an smp kernel
type, etc.)
2. If TIPC is chosen as the mds transport , have you checked the TIPC configuration?
The following TIPC configuration parameters should be set appropriately in nodeinit.conf:
a. TIPC network_id should be the same as ACTIVE system controller's
network_id.
b. The interface information is set with default values. This has
to be set correctly to ensure connectivity between the system
controller and payload nodes.
Also, the TIPC zone_id and cluster_id values are currently hard-coded.
These have to be checked for correctness as below if zone_id and
cluster_id are changed:
c. zone_id should be the same as ACTIVE system controller's zone_id.
d. cluster_id should be the same as ACTIVE system controller's cluster_id.
3. If TCP is chosen as the mds transport with IPv6, have you checked the system configuration?
a. The kernel should be ipv6 compiled.
The following commands should succeed :
- ls /proc/net/if_inet6
- modprobe ipv6
- lsmod |grep -w 'ipv6' && echo "IPv6 module successfully loaded"
b. For communication between ipv6 m/c's, firewall should be disabled.
c. If there is any router in between the m/c's, the router should be ipv6 enabled.
d. kernel should assign ipv6 link-local ip address automatically for the interface available.
4. If TCP is chosen as the mds transport , have you checked the TCP configuration?
The following TCP configuration parameters should be set appropriately in dtmd.conf:
a. DTM_NODE_IP should be configured same as system IP address.
5. Have you checked the slot_id?
The slot_id should be unique and different from any other node. The system
controllers.
6. Have you checked the open source packages installation?
Ensure that the following open source packages are installed
(make install or the rpm packages are installed):
The configure process should have detected the presence or absence of
those packages at runtime.
a. The libxml2 libraries are available and libxml2 include files are
available. In cases of rpm installation, make sure the devel package
is installed.
7. Have you checked the chassis_id? The chassis_id should be the same as
ACTIVE system controller.
8. Have you checked the node_name. It should contain the same name as the
value specified in the nodes.cfg file while generating the imm.xml.
"Unconfigured CLM nodes are not allowed to join the cluster if the node_names
dont match and CLMNA will not allowed to be initialized".
NOTE: Also check for /var/log/messages for any errors during the startup.
Payload Node Checklist
======================
1. If TIPC is chosen as the mds transport ,did TIPC installation fail? The following error "FATAL: Error inserting
tipc (<kernel_modules_dir>/tipc.ko): Invalid module format" indicates that
user had not compiled TIPC with proper kernel files. Compile TIPC with
appropriate kernel header files (e.g. They are different for an smp kernel
type, etc.)
2. If TIPC is chosen as the mds transport , have you checked the TIPC configuration?
The following TIPC configuration parameters should be set appropriately
in nodeinit.conf.payload:
a. TIPC Network id should be the same as system controllers's network ID.
b. The interface information is set with default values. This has to be
set correctly to ensure connectivity between the payload and system
controller nodes.
Also, the TIPC zone_id and cluster_id values are currently hardcoded.
These have to be checked for correctness as below if zone_id and
cluster_id are changed:
c. zone_id should be the same as the system controllers's zone_id.
d. cluster_id should be the same as the system controllers's cluster_id.
3. If TCP is chosen as the mds transport with IPv6, have you checked the system configuration?
a. The kernel should be ipv6 compiled.
The following commands should succeed :
- ls /proc/net/if_inet6
- modprobe ipv6
- lsmod |grep -w 'ipv6' && echo "IPv6 module successfully loaded"
b. For communication between ipv6 m/c's, firewall should be disabled.
c. If there is any router in between the m/c's, the router should be ipv6 enabled.
d. kernel should assign ipv6 link-local ip address automatically for the interface available.
4. If TCP is chosen as the mds transport , have you checked the TCP configuration?
The following TCP configuration parameters should be set appropriately in dtmd.conf:
a. DTM_NODE_IP should be configured same as system IP address.
5. Have you checked the chassis_id? The chassis_id should be the same as
ACTIVE & STANDBY system controllers.
6. Have you checked the node_name. It should contain the same name as the
value specified in the nodes.cfg file while generating the imm.xml.
"Unconfigured CLM nodes are not allowed to join the cluster if the node_names
dont match and CLMNA will not allowed to be initialized".
NOTE: Also check for /var/log/messages for any errors during the startup.
