sddQuarantine
sddQuarantine
Clears or displays the quarantined ports.
Synopsis sddquarantine --clear [[slot/]port | all] [-force]
sddquarantine --show
sddquarantine --help
Description Use this command to clear or display ports that are quarantined by the MAPS action "SDDQ".
The slow drain device quarantine (SDDQ) feature is used to automatically detect the slow-drain devices and move
the slow-drain flows to a low priority virtual channel (VC) from the existing VC (medium or high) thus freeing up the
resources for the regular flows in the existing VC. Due to this automatic isolation from the regular flows, the effects
of the slow-drain flows on the fabric are reduced. Once the traffic flowing through an F_Port is isolated, the F_Port
is marked as Slow Drain Quarantined. You can use the --clear option to clear the Slow Drain Quarantined state on
the port.
If the quarantined ports go offline or disabled, the ports remain in Slow Drain Quarantined state. Once the ports
come online, the flows destined to the port are quarantined.
Notes The execution of this command is subject to Virtual Fabric restrictions that may be in place. Refer to "Using Fabric
OS Commands" and "Command Availability" for details.
Operands This command has the following operands:
--clear
Clears the specified port or all ports from the Slow Drain Quarantined state. This option is
not allowed if the latency or frame loss condition persists on the ports. The -force option
overrides the default behavior. Valid options include the following:
slot
For bladed systems only, specifies the slot number for which to set or display the cost,
followed by a slash (/).
port
Specifies the port number for which to set or display the cost, relative to its slot for bladed
systems. Use switchShow to list of valid ports.
all
Clears all the ports currently quarantined in the local switch.
-force
Clears the quarantined ports even when the latency or frame loss condition persists. This
operand is optional.
--show
Displays all the local quarantined ports, ports on which VC translation is not enforced due to
zoning count restriction, and the fabric-wide quarantined device information.
--help
Displays the command usage.
