The hardware watchdog mechanism can automatically reboot the system in case the system hangs. This can be done with or without first generating an automated crash dump file. As superuser, do one of the following:


•To reboot without generating an automated crash dump file, type:


# eeprom error-reset-recovery=boot



•To reboot and generate an automated crash dump file, type:


# eeprom error-reset-recovery=sync

# swap -l (To verify old swap is deleted)
# zfs set volsize=4G rpool/swap
# swap -a /dev/zvol/dsk/rpool/swap
# swap -l
