Booting from the system boot diskette set

Reasons to boot from diskette

You might need to reboot the filer from the system boot diskette under the following circumstances:

To correct configuration problems
To recover from a lost password
To correct certain disk configuration problems

Restrictions on booting from diskette

Do not boot the filer with pre-6.1 system boot diskettes. The attempt to boot will fail because pre-6.1 software cannot recognize system data from a filer running Data ONTAP 6.1 or later.

Booting from diskette

To boot from a diskette, complete the following steps.

Step	Action
1	Insert the diskette labeled System Boot Diskette 1 into the filer's diskette drive. Note The Data ONTAP 6.4 system boot diskettes are specific to the filer model. 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	If....	Then...
	Your filer is turned on	From the system console, enter the following command: reboot Result The filer begins the boot process.
	Your filer is turned off	Turn on your filer. Result The filer begins the boot process.
3	When the filer's LCD prompts you, remove the diskette and insert the next diskettes into the filer's diskette drive when you are prompted.
4	Press Enter. Result The filer boots and, if it can, displays the following boot menu: 1) Normal Boot 2) Boot without /etc/rc 3) Change Password 4) Initialize all disks 5) Maintenance mode boot Selection (1-5)?
5	Choose one of the boot types shown in the following table by entering the corresponding number.
	Task	Boot type
	Run the filer normally, but from a diskette.	Normal Boot (1)
	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`.	Boot without /etc/rc (2)
	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.	Maintenance mode boot (5)

Configuring a system for netbooting from a filer

To netboot a system from a filer using TFTP, complete the following steps.

Step	Action
1	Place boot programs in the filer /etc/tftpboot directory. You can do this using either NFS or CIFS. Note Boot programs do not necessarily have to be in the /etc/tftpboot directory, but they must be in the directory that is set to be tftpd.rootdir.
2	At the command line of the source filer, enter the following command: options tftpd.enable on
3	Configure the rest of your netbooting environment (BOOTP, DHCP, bootparamd, rarpd, and so on, according to the specific procedure you are using) to use the filer as the TFTP source. Result Your system is now set up for netbooting.

Step

Action

Place boot programs in the filer /etc/tftpboot directory. You can do this using either NFS or CIFS.

Note
Boot programs do not necessarily have to be in the /etc/tftpboot directory, but they must be in the directory that is set to be tftpd.rootdir.

At the command line of the source filer, enter the following command:

options tftpd.enable on

Configure the rest of your netbooting environment (BOOTP, DHCP, bootparamd, rarpd, and so on, according to the specific procedure you are using) to use the filer as the TFTP source.

Result

Your system is now set up for netbooting.

Specifying the TFTP root directory

All relative accesses to files via TFTP are considered relative to the TFTP root directory. All absolute accesses via TFTP can access a file only if it lies in the file system tree rooted at this directory. The default value of this option is /etc/tftpboot.

To specify a TFTP root directory other than /etc/tftpboot, complete the following step.

Step	Action
1	At the command line of the source filer, enter the following command: options tftpd.rootdir pathname Note A valid value for pathname is a fully qualified path name to a valid, existing directory on any volume on the filer.

Enabling console logging of TFTP accessed files

To enable console logging of files accessed using TFTP, complete the following step.

Step	Action
1	At the command line of the source filer, enter the following command: options tftpd.logging on
