safety, safe mode levels 2 and 3 can only be executed from a console with a
local, direct RS232 connection to the V-Switch.

This is the same as resetting the V-Switch. No change is made to the V-Switch
configuration.
Level 1: Last Good Configuration
Each time the V-Switch successfully boots up, it saves the database as the last
good configuration. If the last time the V-Switch booted was also the first time,
the database will be empty. Use this level to erase all configurations executed
since the last reboot and return to the previous V-Switch configuration.
For example, if you are modifying or making temporary changes to the V-
Switch configuration, first ensure that the current configuration is stored in the
V-Switch by resetting the V-Switch then execute the changes. If the changes are
no longer desirable, reboot in this level.
Level 2: Default Factory Database
A direct RS232
connection is
necessary.
This clears the database of all configurations expect user login profiles.
Use this level to erase all virtual configurations expect the user profiles.
For example, if you want to transfer the V-Switch to a different physical
storage pool within a campus, this level will prepare the V-Switch for its
new configuration while maintaining the same user profiles of the same
system administrators.
