What to Do If Rebooting Fails

Language:

If the system does not reboot completely, or if the system reboots and then crashes again, a software or hardware problem might be preventing the system from booting successfully.

Cause of System Not Booting	How to Fix the Problem
The system cannot find /platform/`uname -m`/kernel/sparcv9/unix.	You may need to change the `boot-device` setting in the PROM on a SPARC based system. For information about changing the default boot device, see Displaying and Setting Boot Attributes in Booting and Shutting Down Oracle Solaris 11.3 Systems.
The Oracle Solaris boot archive has become corrupted or the SMF boot archive service has failed. An error message is displayed if you run the `svcs` `–x` command.	Create a second boot environment that is a backup of the primary boot environment. If the primary boot environment is not bootable, boot the backup boot environment. Alternatively, you can boot from the Live CD or USB media.
An invalid entry is in the `/etc/passwd` file.	For information about recovering from an invalid `passwd` file, see How to Boot From Media to Resolve an Unknown root Password in Booting and Shutting Down Oracle Solaris 11.3 Systems.
The x86 boot loader (GRUB) is damaged or the GRUB menu is missing or has become corrupt.	For information about recovering from a damaged x86 boot loader or a missing or corrupt GRUB menu, see How to Boot From Media to Resolve a Problem With the GRUB Configuration That Prevents the System From Booting in Booting and Shutting Down Oracle Solaris 11.3 Systems.
A hardware problem exists with a disk or another device.	Check the hardware connections: Make sure the equipment is plugged in. Make sure all the switches are set properly. Look at all the connectors and cables, including the Ethernet cables. If all these steps fail, turn off the power to the system, wait 10 to 20 seconds, and then turn on the power again.

If none of the above suggestions solve the problem, contact your local service provider.
