The following list describes the example fields:
devId The index of the device in the database
Type The type of interface where the device is attached to the SDG Router
Chan The channel number of the interface
iId
For a SCSI interface only, device ID of the device
tLun For a SCSI interface only, the LUN of the device
UID For a fibre channel interface, unique ID of the device. For SCSI
interface, a constructed unique ID based on the unique ID of SDG Router.
tId Target ID mapping for SCSI initiators
tLun Target LUN mapping for SCSI initiators
Handle An internal pointer used for some diagnostic operations
Itl
An internal pointer used for some diagnostic operations
normalBoot
Certain commands and tests are only available in diagnostic mode.
Switching to diagnostic mode saves all configuration parameters so that
they are restored before returning to normal operation. Use the
normalBoot command to restore the SDG Router to normal operating
conditions.
This command is used only to transition a SDG Router from the special
diagnostic mode to normal operations. It restores the boot parameters that
were copied by
diagBoot
. The new persistent device map is erased, and
the original map file is renamed config/device.map restoring it for use
when the SDG Router restarts. The normalBoot command then restarts the
SDG Router.
reboot
The reboot command requests that the SDG Router shut down existing
operations and then restart. This is the preferred method of restarting the
SDG Router. There are processes running within the SDG Router that
might have writes pending to files within the SDG Router’s flash file
system. Following a
reboot
command, these processes flush their data to
the flash file system, and the flash file system writes all pending data out
to the flash memory. The SDG Router starts a reset cycle only after all
pending data has been successfully written to the flash file system.
