SYNOPSIS

1 normal boot

2 Boot without /etc/rc

3 Change password

4 Initialize all disks OR Initialize owned disks OR Assign ownership and initialize disks for root volume OR No disks assigned (use `disk assign' from Maintenance Mode)

5 Maintenance mode

DESCRIPTION

floppy boot is a mode of the Operating System which is entered after booting from a floppy disk, or after hitting Control-C at the appropriate point during a hard-disk boot.

After initiating a floppy boot, you are presented with a menu of choices, each of which allows you to select a particular type of boot.

OPTIONS

option 1: normal boot
This causes a normal full boot sequence to be done, after which the system behaves just as if a boot from hard disk had been done.

option 2: boot without etc/rc
This does a normal boot, but bypasses execution of the etc/rc file. Following this, the system is running normally, but without the configuration normally provided to it in the etc/rc file. The commands in the etc/rc file can be typed manually to bring the system fully operational. Generally, this command is used when there is something in the etc/rc file which is causing the filer to misbehave. Often, only an ifconfig command and an nfs on or a cifs restart command are done manually, allowing NFS or CIFS to become operational; then the etc/rc file is edited to remove the offending lines, and then the system is rebooted.

option 3: change password
This allows you to change the password of the filer. It is usually used when you have forgotten the current password, and so cannot use the online passwd command.

option 4: initialize all disks
This commands zeroes all the disks of the filer, and re-enters the setup menu. It is typically used only once, at system installation time. This option asks you to confirm its use; once confirmed, there is no way to retrieve data previously on the disks. Zeroing the disks may take time (sometimes hours), depending on how many disks there are, whether they need to be zeroed or not, and what capacity each has.

On systems with software-based disk ownership option 4 will initialize disks which are assigned to the Filer. When no disks are assigned on non gFiler systems, an attempt is made to assign a minimum set of disks for the root volume. After disks are assigned, they are zeroed and then the setup menu is entered.

option 5: maintenance mode
This enters a mode of the system in which a small subset of commands are available, and is usually employed to diagnose hardware (often disk-related) problems. In maintenance mode, WAFL volumes are recognised but are not used, the etc/rc file is not interpreted, and few system services are started. NFS and CIFS cannot be used. Disk reconstructions do not occur. No filesystem upgrade occurs, even if the system is newer than the OS release previously installed.

CLUSTER CONSIDERATIONS

It is generally recommended that you explicitly disable clustering or halt the other system (to the `ok' prompt, or powered off) before entering the various floppy boot menu choices on this system. Failure to do this can sometimes result in takeovers by the other node while you are in maintenance mode; this is usually undesirable.

SEE ALSO

NOTES

A floppy boot menu choice affects only a single boot of the OS. If you want, in the future, to continue to boot the same version of the OS from the hard disk, you must intall that OS on the hard disk using the untar installation process and the download command.
