Caution

Winnowing the database might cause unattached devices to change
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 5100. You must reboot the SNC
5100 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.
