3.Reboot the system with the following command:

# /usr/sbin/shutdown -y -i0 -g0

The system displays the ok prompt.

4.Create a device alias for the new boot device by entering the following command (for example):

ok nvalias bootdevice2 <device>

Replace <device> with what you recorded in item 2. For the example shown, you would replace <device> with the following:

/sbus@3,0/SUNW,fas@3,8800000/sd@2,0

5.Test the alternate boot device name by entering the following command:

ok boot bootdevice2

6.Reboot the system as usual and verify that everything is normal. Ignore any warnings you may get about a “forceload” failing.

7.Enter the following command:

# crontab -e

The system starts the editor and loads the cron file.

8.Find the line for /olds/chkDisks and take one of the following actions:

If the line is commented out, uncomment it by deleting the pound sign at the beginning of the line.

If there is no line for /olds/chkDisks, add the following line to

the end of the file:

15 0 * * * /olds/chkDisks > /dev/null 2>&1
