What to Do If Rebooting Fails

Note –

Some of the information in this section pertains to systems that are running the Oracle Solaris 10 release only.

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

Cause of System Not Booting 

How to Fix the Problem 

The system can't find /platform/`uname -m`/kernel/unix.

You may need to change the boot-device setting in the PROM on a SPARC based system. For information on changing the default boot device, see How to Change the Default Boot Device by Using the Boot PROM in System Administration Guide: Basic Administration.

Oracle Solaris 10: There is no default boot device on an x86 based system. The message displayed is:

Not a UFS filesystem.

Oracle Solaris 10: Boot the system by using the Configuration Assistant/boot diskette and select the disk from which to boot.

Solaris 10 1/06: The GRUB 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.

Solaris 10 1/06: Boot the failsafe archive.

There's an invalid entry in the /etc/passwd file.

For information on recovering from an invalid passwd file, see Chapter 12, Booting an Oracle Solaris System (Tasks), in System Administration Guide: Basic Administration.

There's a hardware problem 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 this fails, 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.
