Booting from system boot diskette

Boot from diskette to correct some types of problems

You might need to reboot the filer from the system boot diskette to correct configuration problems, recover from a lost password, or correct certain disk configuration problems.

Restrictions on booting from diskette

Do not boot the filer with a pre-5.0 system boot diskette. The attempt to boot will fail because pre-5.0 software cannot recognize system data from a filer running Data ONTAP 5.0 or later software.

If your file is using clustering, do not boot with a pre-5.2 system boot diskette. Releases earlier than 5.2 do not support clustering.

If you need to run an earlier release of Data ONTAP on the filer, contact Network Appliance Technical Support, as described in "Getting technical assistance", for instructions about how to downgrade your filer.

Procedure for booting from diskette

Complete the steps in the following table to display the boot menu from a diskette. Booting from the diskette takes longer than booting from the hard disk.

Step Action
1 Insert the diskette labeled System Boot Disk 1 into the filer's diskette drive.

Note: The Data ONTAP 5.2 system boot diskettes are specific to the model of filer that you are updating. You received diskettes appropriate to the model you are updating. If you have different models, be sure to check the diskette labels to make sure you're using the correct diskettes for the filer.

2 From the system console, enter the reboot command or, if the system is powered off, power it on.
Result
The filer begins the boot process.
3 When the filer's LCD prompts you to, remove the diskette and insert the diskette labeled System Boot Disk 2 into the filer's diskette drive.
4 Press the Enter key on your console.
Result

The filer boots and, if it can, displays the boot menu, shown below:

1) Normal Boot

2) Boot without /etc/rc

3) Change Password

4) Initialize all disks

5) Maintenance mode boot


 

Selection (1-5)?

Choose one of the boot types shown in the following table by entering the corresponding number.




 
Boot type

 
Description




 
Normal Boot (1)

 

Use Normal Boot to run the filer normally, but from a diskette.





 
Boot without /etc/rc (2)

 

Use Boot without /etc/rc to troubleshoot and repair configuration problems.

 



Note: Booting without /etc/rc causes the filer to use only default options settings, disregard all options settings you put in /etc/rc, and disable some services, such as syslog.
 






 
Maintenance mode boot (5)

 

Use Maintenance mode boot to go into Maintenance mode and perform some volume and disk operations and get detailed volume and disk information. Maintenance mode is special for the following reasons:


     

  • Most normal functions, including file-system operations, are disabled.
 

  • A limited set of commands is available for diagnosing and repairing disk and volume problems.
 

  • You exit Maintenance mode with the halt command.
