Reverting from DCB to non-DCB configuration (optional)

One method to revert from a DCB-configured switch to a non-DCB-configured switch is to delete the
current configuration (startup-config) and follow the steps in section 2. If deleting the current
configuration is not an option, use the following procedure to unconfigure DCB and enable standard flow
control.
Note: This is a disruptive operation that requires down time. The arrays will temporarily lose
communication with each other. Power off all arrays and hosts connected to the SAN before proceeding
with these steps.
4.1

Disable DCB

Dell#configure
Dell(conf)#no dcb enable
Dell(conf)#exit
4.2

Remove DCB policies and apply standard flow control

Dell#configure
Dell(conf)#interface range tengigabitethernet 1/1-48
Dell(conf-if-range-te-1/1-1/48)#no dcb-map profile-name
Dell(conf-if-range-te-1/1-48)#flowcontrol rx on tx off
Dell(conf-if-range-te-1/1-48)#exit
Dell(conf)#interface range fortyGigE 1/49 , fortyGigE 1/50
Dell(conf-if-range-fo-1/49,fo-1/50)#no dcb-map profile-name
Dell(conf-if-range-fo-1/49,fo-1/50)#flowcontrol rx on tx off
Dell(conf-if-range-fo-1/49,fo-1/50)#exit
Dell(conf)#exit
4.3

Revert to default VLAN ID on switch and arrays

Once DCB is disabled on the switch, the PS Series arrays will no longer use the VLAN ID that was
configured when DCB was enabled. The arrays will revert to the default or native VLAN. Therefore, a valid
VLAN must be configured for all host servers, switches, and PS Series array members. A valid VLAN can use
the default or native VLAN ID (typically 0 or 1), or a specific VLAN can be configured (for example, VLAN
100). If a non-default VLAN is configured, then any ports connected to the arrays must be configured as
"untagged".
Note: Host NICS must also be updated with matching VLAN information.
