Running Diagnostics
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
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
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
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
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
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:
