C7000 - decomm 2 C7000 Frames and creating new Domain

Good day All,

Welcome back!!! recently we had a request to decomm 2 C7000 Frames which are part of the 4 Frames Linked Frames.
Kindly note as the decomm is for the Primary frame in the domain we will need to re-create a new domain.

Pre-task to be done:

1. Backup the currect VC domain in case if we have to revert back
2. All Server Profiles complete screen shot showing which NIC is configured on the Server
3. Shared uplink set screen shot showing the ports which are configured to uplink switches.
4. All Ethernet networks information which are associated to all the Shared uplink sets and VLAN's
5. Need to determine if you want to use a old name or a new Name for the domain
6. What would be the IP for the new domain
7. Who will remove the existing cables from 4 frames and how to configure new stacking links only for 2 frames.
8. If direct attached SAN is present all the information needed to recreate should be taken
9. All blade Servers will need to shutdown and we will have to recreate all the Shareuplinks,Ethernet networks and Servers profiles so for the whole activity at-least 12-14 hrs of downtime. We may need more in case we run into issues so plan your downtime well.

Note: All our blades are using the Factory default settings for MAC address so no additional information needed to be captured. If you have to use the domain then need to determine what series will be used for it.


Stacking Links connected requested as below:

Frame 1 Interconnect Slot 1 port 1 Frame 2 Interconnect Slot 1 port 1
Frame 1  Interconnect Slot 2 port 1 Frame 2 Interconnect Slot 2 port 1


During the change Window:

1. Shutdown all the Server blades
2. Login to VC and Un-assigned all the Ethernet networks for each Servers in the profile for all profiles in all 4 frames
3. Deleted all the Ethernet networks on all the frames
4. Deleted all the Shared uplink ports on all the frames.
5. Now click on enclosure and under configuration deleted the 2 Frames which you will be reused to create new domain (Note: delete domain can be done too now )

Note: You will not be able to delete domain or delete a enclosure without blades are been shutdown and Ethernet networks been unassigned in Server profiles and shareuplink sets are deleted.

6. Now request the cabling guy to connect the stacking links and confirm he is done before you proceed

7. Now login to OA for the Primary frame , click on Enclosures IP4 and make sure all the VC IP and ILO for the blades are intact.

Note: if this new domain creation then you will need to configure you OA first with IP for all the VC Modules and ILO for Server blades.

8. Now use the IP for VC1 module and connect ,as soon as you authenticate you will notice that domain configuration wizard will start
First step is to configure domain name .Click next will ask you import the current enclosure module, give the password and hit next and module should be imported and then at the end before  you click finish you see a option to un-check  configure network just un-check it as we will do it later.

9. Now click on Configurations , go to IP Address tab and click use Virtual connect domain IP and provide the VC domain IP,

10. you will notice that current session will be logged out and will be redirect to new VC domain IP

11. Logged back and started creating the Shared uplink Sets. Note that all the uplinks will be in standby mode don't worry after you add ethernet networks and assign to Server profile the uplinks will come online.

12. Now started to create Ethernet networks

13. Created new Server profile and assigned the Ethernet networks for the NIC's as it was before

14. Powered on the blades and the Servers came back online with no issues and no need to reconfigure IP's because we used Factory default of blades so no mac-address got changed even though new Server profile was attached.

15. Completed the creation for all the frames and it was handed over for testing.

So this is how we successfully decommission 2 Frames in the 4 frame domain and recreated a new domain.

How to make sure stacking links are connect properly:

After logging to VC, when you click on Stacking links you will the connecting Status and redundancy status showing all OK.

Also i have see people finding default to understand see below, marked in yellow is the external cable links we requested engineer to connect and if you see the other connections they are just internal wired connections between 2 VC modules which are adjacent to each other in  frame.
Example : Connection from VC1 to VC 2 module

Note: Always make sure that VC modules id more than 1 frame are created as parallel, should never connect cross cabled.



















So this is how we successfully completed the request and sharing the same so that it helps someone!!!
Until next one you all have good day!!!!!!!!!!!!!!!!!!!!!!!!!!!
