After the BIOS, for the N2200-ON and N3200-ON/E3200-ON Series, POST runs to verify the devices that are required to boot
to ONIE GRUB.
POST
POST diagnostics verify the system DRAM, DIMM, SPD, memory, RTC/NVRAM, and PCI devices. Test configuration
parameters and test results are saved in NVRAM.
Capture support data from ONIE
1.
Capture support data to the screen.
ONIE:/ # dmesg
2.
Capture support data to the
onie-support.tar.bz2 gzip
file.
ONIE-support creates the support file. To store the file, enter the location; for example,
