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.
