| ====== Troubleshooting ====== | |
| {{indexmenu_n>2}} | |
| In case DPI did not start after the upgrade please check: | |
| - The drivers are installed: <code>ls /lib/modules/`uname -r`/extra</code> The drivers pf_ring.ko and ixgbe.ko (or igb.ko) are present in the directory. If no - please reinstall them: <code>yum reinstall dna-ixgbe</code> Alternatively, if the network card is 1G: <code>yum reinstall dna-igb</code> If the network connection was lost (the network interface for control has the same type as DPI), [[..:..:..:dpi_update_10:dpi_10_fix:errata_3|install the old drivers temporary]] and execute reinstall to replace them by new ones after getting back the network connection. | |
| - The driver is loaded: <code>lsmod|grep ixgbe (или igb)</code> If no, load it: <code>depmod -a | |
| modprobe ixgbe (or igb)</code> If the network card is 1Gb, use igb instead of ixgbe in all commands. | |
| - Interfaces are running: <code>ifconfig</code> If not, then activate them: <code>ifup dna0;ifup dna1</code>Check that configuration files of the interfaces in use have parameter ONBOOT=«yes» <code>cat /etc/sysconfig/network-scripts/ifcfg-dna0</code> | |
| - Interfaces are in working conditions: <code>cat /sys/class/net/dna?/operstate</code> This instruction has to return "up". If not, reboot the computer or the interface.<code>service network restart</code> | |
| - The process is running. If not, start it: <code>service fastdpi start</code> | |
| - For network cards with bypass support: check that the bypass driver is installed and bypass mode is switched off after start program's start: <code>bpctl_util all get_bypass</code> If not, [[en:dpi:update:errata:errata_3|repair the driver according to the manual (item 2)]] and restart the process. | |
| - If the driver can not be loaded because it is binary incompatible with the new kernel version: request loading of the last kernel version in /etc/grub.conf:<code>default=1</code> and contact tech support. | |
| | |
| Please contact tech support otherwise. | |
