Deployment Guide

of the base device logout causing all NPIV devices to log out, the base device logout affects only the
base device; the NPIV devices stay logged in.
Difference in the device logout behaviors
A base device is a device on an F_Port that has the base PID. The base device logs in with a FLOGI.
An NPIV device is a device on an F_Port which has an NPIV PID. An NPIV device logs in with an
FDISC.
The following table summarizes the difference in the base and NPIV device logout behaviors with and
without the base device logout feature enabled.
Base and NPIV logout behavrioursTABLE 82
Scenario Without base device logout enabled With base device logout enabled
• No device is logged in. • Requires a device with a base PID to
log in to the F_Port before any NPIV
device can log in.
• Requires a device with a base PID
to log in to the F_Port before any
NPIV device can log in.
• Base device is logged in. • Allows NPIV devices to log in and log
out.
• Permanent Port Name (PPN) is
assigned with PWWN of the base
device for all the devices logged-in on
that port (for both base and NPIV
devices).
• Allows NPIV devices to log in and
log out.
• Permanent Port Name (PPN) is
assigned according to FC-GS-6
(5.2.3.13) standard.
• Base device is logged in.
• At least one NPIV device is
logged in.
• If the base device is logged out, then
all the NPIV devices are also logged
out.
• Removes routing information when
the base device logs out.
• Allows base device to log out while
NPIV devices are still logged in.
Indicates that the base device is
logged out in the switchShow
command output.
• Does not remove the routing
information.
• Base device is logged out.
• At least one NPIV device is
logged in.
N/A • Allows base device to log back in as
a base or NPIV device.
• Allows NPIV devices to log in and
log out.
• Does not remove the routing
information.
• Base device is logged out.
• All NPIV devices are also
logged out.
• Requires a device with a base PID to
log in to the F_Port before any NPIV
device can log in.
• Removes all the routing information.
• Requires a device with a base PID
to log in to the F_Port before any
NPIV device can log in.
Enabling base device logout
Both the active and the standby switches/AGs should be upgraded to Fabric OS 7.3.0 or later.
