SNC 5100
Boot Mode Commands
diagBoot
This command is used only to transition an SNC 5100 from normal operations
to the special diagnostic mode.
Caution
All SCSI and FC cables must be disconnected before entering the
diagBoot command.
• The diagBoot command first ensures that the /nvfs:mt directory
exists.
• It copies the existing bootline to a file in the
/nvfs:mt directory on the
SNC 5100.
• It installs a new bootline directing the SNC 5100 to boot using a special
diagnostic startup script /ffs:mt/diagnstk.rc.
• It renames the persistent map file
config/device.map as
config/device.bak (a new file will be generated after rebooting).
• It issues a
reboot command to put the changes into effect.
normalBoot
The normalBoot command is used only to transition the SNC 5100 from the
special diagnostic mode to resume normal operation.
• It restores the bootline that was copied by
diagBoot.
• It erases the new persistent device map and renames the original map file
config/device.map – restoring it for use when the SNC 5100 reboots.
• It reboots the SNC 5100.
Diagnostic Commands
This section is a reference for the commands that are available when the SNC
5100 is booted in diagmode.
The command set is limited while in
diagmode. You will need to use the
showBox command and three commands (with the suffix Test) when testing
the Ethernet, Fibre Channel, and SCSI interfaces.
