Collapse a SuperDome to a Single nPar

[Alzhy]

Currently 4 nPars. And I just would like to be sure the procedure is as follows:

1. Shutdown all nPars except one that contains cell 0 (really need to be cell 0?)
2. From that nPar - shutdown all the other 3 nPars.
3. parremove -p npar2 (npar3 and npar4)
4. parmodify npar0 to add the freed cells from nPar 2,3,4.
5. Reconfig Reboot -- "shutdown -Ry"
7. Done.

My steps correct?

Nelson!

I can answer the first one, it really does not need to be cell 0, it only need to be core capable!

Regards,

Jaime.

Just done this recently

1. Shutdwn all but one of the Npars, using -H to force them to go to BIB ready for a Reconfiguration Reset

2. From the remaining Npar, use parremove -p

3. parmodify -p -a

4. use parstatus to see if all cells are included, this can also be done from the GSP command screen using cp command

5. Shutdown for a Reconfiguration with shutdown -R -y 0

6. On the VFP, select the remaining Npar and wathc to see all cells join in

Don't have to be Cell 0 Npar. It could be any Npar which is core capable (see previous post).

once you shutdown remaining 3 Npars.
Add freed cells to Npar1.
your 5th step should do the magic for the rest.

Melvyn,

What if I simply shutdown the other nPars via "shutdown -hy"?

Thanks !

[melvyn burnard]

if you halt the partitions with just shutdown -yh then when you go to reboot the last partition you will find that the cells will not join the partition.
Also you will probably not be able to parremove the partitions

And i will have to do an RR on my MP right?

Thanks!

If you do the shutdown -Ry 0 command which will reconfigure Npar (because you modified partition profile) then don't have to do RR at MP.
