Hi,
i have a Nexus 7009 with two SUP2E running NX-OS 6.2(22); the Switch has 2 M1 Linecards which have to be raplaced by M3 Linecards N7K-M348XP-25L=

Any suggestions howto replace M1 Linecards with M3 Linecards, without loosing the
port-configuration.
Thanks in advance

Suggest to look at the comparability matrix :
Once it is satisfy the requirement, and you do not have empty slot for new M3 card, you need eject the old and one and insert and test.
in this stage all the connection connected to slot that port will be loss of connectivity.
if Nexus have Pair configured, you can replace one at a time in each chasis, you need to copy the port configuration, since new module may need to put the configraiton back again once newly install moduled installed and configured.
Other note : if this is vDC environment you need allocate new resources to correct vDC.

Hi
Did you end up getting and answer to this question as well as going thru and replacing the m1 with m3 cards and what was the outcome ? I am looking at similar process but going from M2 and F2 to F3 cards on same vdc ?
Thanks

We did not do the replacement yet but I did confirm with TAC that the configuration is lost when changing cards. As long as the slots remain the same, you should be able to cut & paste the config word for word. The only caveat to that would be if the port time was changing. For example, if you're going form GigabitEthernet ports to TenGigabitEthernet ports.

Thanks for that so config will be lost once new card goes in and restore from back up then. I ad this plan below for trying to preserve the config but by sounds of it its a mute point anyway Also should we suspend the vdc at some point in the process when replacing the card ?
First step
F2 swap out to F3
1) Logical shut down of all interfaces on line card 5 N7K-F248XP-25E i.e. shutdown interfaces xx
2) Power down line card 5 module N7K-F248XP-25E
3) Remove line card 5 and cables
4) Insert F3 N7K-F348XP-25 line card into slots
5) Patch cables to F3 card
6) On the admin vdc change resource allocation to limit-resource module-type m2xl F3
7) Power up line card 5
8) Un shut interfaces and confirm are working and showing up in PROD-B vdc
9) Copy config to startup
Second steps
M2 swap out to F3
1) Logical shut down of all interfaces on lines cards 3 and 4 N7K-M224XP-23L i.e. shutdown interfaces xx
2) Power down line card 3 and 4 module N7K-M224XP-23L
3) Remove line card 3 and 4 and cables
4) Insert F3 N7K-F348XP-25 line card into slots
5) Patch cables to F3 cards
6) On the admin vdc change resource allocation to limit-resource module-type F3
7) Power up line card 3 and 4
8) Unshut interfaces and confirm are working

Hi Manfred
Thanks for sharing your process for the M1 to M3 cards that is much appreciated. based upon what you were doing I have created my process to migrate from M2 and f2 to F3 does this seem logical from your experience ?. As M2 F2 and F3 cannot co exist same time in the VDC mine may be easier just to go straight to F3
Thanks again
PROCESS FOR CARD LINE CARD REPLACEMENT
Step 1
Log into admin vdc
vdc admin-vdc
copy running-config startup-config vdc-all
copy all vdc configs off the box
Step 2
Shut down interfaces on all line cards in production vdc prd-cs-a
conf t
interface xxxxx
shut
Step 3
Shutdown all of the I/O module line cards from admin VDC:
poweroff module 3
poweroff module 4
poweroff module 5
confirm they are down
show module 3
show module 4
show module 5
Step 4
Purge Modules 3,4 and 5 from admin vdc
purge module 3 running-config
purge module 4 running-config
purge module 5 running-config
Step 5
save config from admin vdc
copy running-config startup-config vdc-all
Step 6
Remove F2 and M2 line card from switch and insert F3 cards
Physically remove modules from switch
Insert new F3 lines cards into modules
Patch cables to F3
Step 7
no poweroff module 3
no poweroff module 4
no poweroff module 5
no poweroff module 6
confirm they are up
show module 3
show module 4
show module 5
show module 6
step 8
unallocate interfaces from prod vdc prd-cs-a
no allocate interface Ethernet3/1-24
no allocate interface Ethernet4/1-24
no allocate interface Ethernet5/1-48
Step 9
Log In admin VDC and allocate F3 resource to prod vdc prd-cs-a vdc
limit-resource module-type f3
allocate interface Ethernet 3/1-48
allocate interface Ethernet 4/1-48
allocate interface Ethernet 5/1-48
Step 10
Restore line card configuration to new line cards from backup text file back up – copy and paste

Hi Manfred
Thanks for the feedback. Yes we are going to allocate line card 5 and 6 actually to another vdc later on so updated step 9 to only allocate line card 3 and 4 back to the prd-cs-a vdc and we will add just move the config from line card 5 to line card 4 manually. Line card 5 only has 3 or 4 ports configured so easy to move manually. We are happy to do manual copy and paste of all the prd-cs-a config back in for everything as it is not a huge config file
Cheers
Thank again for your advise/help
step 8
unallocate interfaces from vdc prd-cs-a
no allocate interface Ethernet3/1-24
no allocate interface Ethernet4/1-24
no allocate interface Ethernet5/1-48
Step 9
In admin VDC allocate F3 resource to prod vdc prd-cs-a vdc
limit-resource module-type f3
allocate interface Ethernet 3/1-32
allocate interface Ethernet 4/1-32
Step 10
Restore line card configuration to new line cards from backup text file back up – copy and paste
