Solaris 10 1/06: If a system crash occurs in the GRUB based boot environment, it is possible that the SMF service svc:/system/boot-archive:default might fail when the system is rebooted. If this problem occurs, reboot the system and select the failsafe archive in the GRUB boot menu. Follow the prompts to rebuild the boot archive. After the archive is rebuilt, reboot the system. To continue the boot process, you can use the svcadm command to clear the svc:/system/boot-archive:default service. For more information on GRUB based booting, see Booting an x86 Based System by Using GRUB (Task Map) in System Administration Guide: Basic Administration.
