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
After initiating a floppy boot, a menu of choices is presented that allows for the selection of the desired type of boot.
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 the filer password to be changed. It is usually used when the administrator has forgotten the current password, and so cannot use the online passwd command.
option 4: Initialize all disks
This commands zeroes all the filer's disks and re-enters the setup menu. It is typically used only once, at system installation time. This option asks for confirmation; 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 initializes disks that are assigned to the system. If no disks have been assigned on systems other than V-Series systems, the software attempts to assign a minimum set of disks for the aggregate containing the root volume. After disks are assigned, they are zeroed and the user enters the setup menu. For V-Series systems the user must use option 5 to assign at least one disk (LUN) from the storage subsystem, then use option 4 to create the root volume. After disks are assigned, they are zeroed and the setup menu is entered.
option 5: Maintenance mode boot
This enters a mode in which a small subset of commands are available, and is usually employed to diagnose hardware (often disk-related) problems. In maintenance mode, WAFL aggregates and traditional volumes are recognized 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.
