Description

This article describes the steps to be taken when the device fails to boot up during boot-up process (reboot or power-cycle) / format install.

Symptoms

The below error logs would be seen during the boot-up process on console :

 

t='/dev/ram0'

rootfs=''

fstype='ramfs'

initdebug=''

NEWROOT='/sysroot'

ata5: COMRESET failed (errno=-16)

ata5: COMRESET failed (errno=-16)

Power down.

Solution

As per the above logs, the error message ata5: COMRESET failed (errno=-16) indicates that the system is unable to reset the SATA disk 1. This error message is usually caused by a disk failure or a loose connection between the disk and the motherboard.

The switch attempted to reset ATA channel 5 but ultimately failed and decided to give up and since not finding the expected SATA disks, the system decides to halt.

There are number of reasons for SSD to fail and few of the reason could be due to Controller failure [SSD controller manages data storage and retrieval. If it fails, the SSD may become inaccessible] and other possible could be due to corrupted firmware on SSD itself.

 

The device ends up in RMA, as it doesn't complete the boot process.
