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.
