Nexus 6K and Fabric extender 2248QT

I have Nexus 6000. I have accidentally deleted port channel as below config and I like to regain. Before I made changes config looks like below.

interface Ethernet2/1/1

interface Ethernet2/1/2

interface Ethernet2/1/3

interface Ethernet2/1/4

interface Ethernet2/2/1

interface Ethernet2/2/2

interface Ethernet2/2/3

interface Ethernet2/2/4

interface Ethernet2/3
  description vpc peerlink
  switchport
  switchport mode trunk
  spanning-tree port type network
  channel-group 1 mode active

interface Ethernet2/4
  description vpc peerlink
  switchport
  switchport mode trunk
  spanning-tree port type network
  channel-group 1 mode active

After I tried making changes related to Fabric extender , I have entered below command:

poweroff module 2
no poweroff module 2

Now config on Nexus looks like below.

interface Ethernet2/1/1

interface Ethernet2/1/2

interface Ethernet2/1/3

interface Ethernet2/1/4

interface Ethernet2/2/1

interface Ethernet2/2/2

interface Ethernet2/2/3

interface Ethernet2/2/4

interface Ethernet2/3/1

interface Ethernet2/3/2

interface Ethernet2/3/3

interface Ethernet2/3/4

interface Ethernet2/4/1

interface Ethernet2/4/2

interface Ethernet2/4/3

interface Ethernet2/4/4

I can get interface 2/3/1-4 & 2/4/1-4 not show up as above and How do I config back port channnels 2/3 and 2/4 as shown in above original config?

Thank you

I assume your vPC cdomain and whatnot is not functional at the moment.

What errors are coming up when you try to reconfigure those ports?

You may just want to scrap the config and start from step one on rebuilding the vPC domain.
