Figure 7-8 shows the fastboot command which is a warm reboot that bypasses power-on self-test (POST).
Figure 7-8. fastboot Command Example
flashDefault
Figure 7-9 shows the flashDefault command, which resets the switch to the factory default configuration
values.
This command may not be executed on an operational switch. You must first disable the switch using the
switchDisable command.
Figure 7-9. flashDefault Command Example
flashDefault also configures the switch to boot from its flash proms (removes any network boot parameters),
erases the SNMP database, and erases the Zoning database. If any changes have been made to the SNMP
configuration or Zoning configuration from the default values, then the factory default does not take effect
until the next reboot because the values are stored in cache.
For this reason it is recommended to always reboot the switch immediately after flashDefault.
flashDefault does not change the switches identity: Worldwide Name, Ethernet IP address and subnetmask,
gateway address, symbolic name, or license keys.
This command should be used with care; flashDefault restores the configurable parameters to factory
default values, as follows:
Switch modes: tachyon, isolated, notypes, nomcast, nopost
FC parameters: domain, BB_credit, RA_TOV, ED_TOV
FL_Port parameters: collection method, credit, FAN frames
Virtual channel parameters
syslogd IP address
Fibre channel IP address and subnetmask
Display error level
Original equipment manufacturer (OEM) customizing
Static paths
Usernames and passwords
flashDownload
Figure 7-10 shows the flashDownload command which is used to download firmware into flash memory.
This command can be executed on an operational switch. A reboot is required to initiate the new firmware
after the download has completed.
Firmware can be downloaded from either a UNIX
®
host, Windows
®
95, or Windows NT host. For a UNIX
host, no special software is needed. For Windows 95 or NT, the Dell PowerVault™ Utilities Diskette provides
