Migrating MCSG to a new server platform

[Mike Bruner]

If migrating MCSG to a new server platform D-Class to rp5470, do the Pseudo names need to be changed. How do you change the Pseudo name?

[melvyn burnard]

Would youy care to explain a bit more?
What Psuedo name are you referring to?

[Mike Bruner]

I am refering to the network address Pseudo names.

hi,

are you referring to package names? Can you pls give an example from the cmviewcl output or a a cluster config file on what term/value you are referring to.

thanks

Hi:

I don't think we understand you yet. Are you referring to the package hostnames? If so, they are simply entries in /etc/hosts, NIS, or DNS - whatever you use for normal hostname resolution. MC/SG only cares about IP addresses. The IP Addresses that don't move - the stationary address and the package IP addresses that can move.

Hello,

Like stated already, if what you are referring to are the virtual hosts that are associated with the package ip addresses, then you needn't concern yourself with that as MCSG only manages the ip address itself. If you are using the /etc/hosts file just be sure the virtual hosts are in there and then just add the node(s) to the cluster using cmquerycl, run your cmcheckonf and cmaplyconf and bring the node(s) into the cluster, which may be done online. when you are satisfied that your new configuration will work, just delete the old nodes out of the cluster, if that is your plan (also online). Make sure you save your old cluster config first with cmgetconf in case things go awry.

Good luck
Chris

I think he may be referring to the host alias' created for the heartbeat IPs - required when configuring the NICs thru SAM.

As long as these are direct connect & not physically in the network the IPs & host alias' can be whatever you want & should be placed in the hosts file.

These are not "created" by any cmxxxx command you have to set these up via SAM, ifconfig or brought over with the netconf file.

Rgds,
Jeff
