Type
The type of interface where the device is attached to the SNC 4000.
Chan
The channel number of the interface
iId
For a SCSI interface only - device ID of the device
iLun
For a SCSI interface only – Logical unit number of the device.
UID
For a FC interface – Unique ID of the device. For SCSI interface, a constructed Unique
ID based on the SNC 4000's Unique ID.
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.
mapWinnowDatabase
Occasionally, you may want to eliminate inactive entries from the database. The mapWinnowDatabase
command reduces the database to only the devices presently attached. The address mapping of the current
devices will not be altered.
SNC4000 > mapWinnowDatabase
0xc0ac8340 (tShell): Wrote 4 device maps to file 'nvfs:config/device.map'
value = 4 = 0x4

Winnowing the database might cause unattached devices to change
CAUTION
addresses unpredictably if they are reattached. Use this command
only when you are sure that the devices you are interested in are
connected and available to the SNC 4000. You must reboot the SNC
4000 after executing this command for the new setting to take effect.
mapWinnowDatabaseLun [dev ID]
The mapWinnowDatabaseLun command acts like the existing function mapWinnowDatabase except that
it operates on only one specified LUN, which is input as a parameter. The mapWinnowDatabaseLun
command operates against the device list output by the mapShowDatabase command. Issue the
mapShowDatabase command before and after issuing the mapWinnowDatabaseLun command to verify
functionality.
The mapWinnowDatabaseLUN command frees the LUN for use in the device map. If the LUN is currently
assigned to an attached device, no action is taken. If the LUN refers only to historical data (device not
currently attached), the LUN is freed for reuse.

mbufShow
The mbufShow command displays statistics about the distribution of mbufs on the Ethernet network.
Interpreting these statistics requires detailed knowledge of Internet networking protocols. This information
may be useful to the LAN administrator.
