Running Diagnostics
Before running HyperFabric diagnostics:
1. Confirm HyperFabric adapters are installed on each node. Use the following
command to display a list of HyperFabric adapters installed each node:
ioscan -funC clic
2. Check to see if HyperFabric software is installed. Use the following command to
display the HyperFabric software version installed on each node:
swlist | grep -i hyperfabric
3. Check the patch level. Use the following command to display the list of patches
installed on each node:
swlist
Refer to the HyperFabric Release Note to determine which patches need to be
installed.
4. Make sure the HyperFabric subsytem is started. Use the following command to
determine if the HyperFabric subsystem is running on the node:
• ps -ef | grep clic
If the HyperFabric daemon (clic_mgmtd) is not running, start the HyperFabric
subsystem by executing the following command:
/opt/clic/bin/clic_start
5. Make sure the correct IP addresses are assigned to the HyperFabric adapters. Use
the following command to display all of the network interfaces and the IP addresses
assigned to them:
netstat -in
If an IP address is not assigned to a HyperFabric adapter, execute the following
commands in the order listed:
clic_shutdown
clic_init
clic_start
All of these commands reside in the /opt/clic/bin directory.
6. Check cabling to make sure all of the HyperFabric adapters are connected to the
fabric.
7. Run the following command:
/opt/clic/bin/clic_stat -dALL
If a TCP/UDP/IP application is running:
Check the firmware file field to make sure the same version of firmware is
downloaded on all of the HyperFabric adapters in the cluster. If this is not
the case, run the following commands in the order listed below:
