Diagnostics VRTX Chassis
update file vrtx_cmc.bin. This is the same firmware image file used for normal firmware updates.
The recovery process displays its current activity and boots to the CMC OS upon completion. When
you type recover on the recovery prompt, the recover reason and available sub-commands display.
An example of a recover sequence is given here.
recover getniccfg
recover setniccfg 192.168.0.120 255.255.255.0 192.168.0.1
recover ping 192.168.0.100
recover fwupdate -g -a 192.168.0.100
In recover mode, you cannot ping CMC normally, because there is no active network stack. The
recover ping <TFTP server IP> command allows you to ping to the TFTP server to verify the
LAN connection. You must to run the recover reset command after running setniccfg on some
systems.
Racdump
The racdump subcommand provides a single command to get comprehensive chassis status,
configuration state information, and the historic event logs. The racdump subcommand displays the
VRTX Chassis information such as General system/RAC information, CMC information, Chassis
information, Session information, Sensor information, Firmware build information, Chassis logs, and
SEL Logs.
From the racdump command, the Chassis Information can be gathered and can be used for
troubleshooting.
Power Troubleshooting
The following information helps you to troubleshoot power supply and power-related issues:
Issue: Configured the Power Redundancy Policy to AC Redundancy, and a Power Supply
Redundancy Lost event was opened.
A. Resolution: This configuration requires at least one PSU in grid A (the top two slots) and
one PSU in grid B (the bottom two slots) to be present and functional in the modular
enclosure. Additionally, the capacity of each grid must be enough to support the total
power allocations for the chassis to maintain AC redundancy. (For full AC Redundancy
operation, make sure that a full PSU configuration of four PSUs is available.)
B. Resolution: Check if all PSUs are properly connected to the two AC grids; PSUs in grid A
must be connected to one AC grid, those in grid B must be connected to the other AC grid,
and both AC grids need to be functional. AC Redundancy is lost when one of the AC grids is
not functioning.
Problem: The PSU state is displayed as Failed (No AC), even when an AC cord is connected and the
power distribution unit is producing good AC output.
A. Resolution: Check and replace the AC cord. Check and confirm that the power distribution
unit providing power to the PSU is working as expected. If the issue still persists, call your
service provider for a PSU replacement.
B. Resolution: Make sure that the PSU is connected to the same voltage as the other PSUs. If
CMC detects that a PSU operating at a different voltage, the PSU is turned off and marked
Failed.
