How to move the CELL from superdome partition

[Mani K]

Hi All,

Lets assume this is the scenario,
config:-
SUPERDOME 64way
I have one partition (P=1) having 3 cell board (1,2,3) IO chassis ( 0/0/1)

partion No:2 having 2 cell board (5,6)and IO chassis ( 0/0/3)

Assume DB=ORACLE..
Both are working..

Now i want to move the cell board 3 from partion1 to partion 2.

The procedure i would like to use is as follows....

PARTITION 2:
1.shutdown -R -H

PARTITION 1:

1.parmodify -p1 -d3
2.parmodify -p2 -a3:base:y:ri -B
3.shutdown -R

IS this correct..
pls share your opinion.

thanks and regards,
Mani

Hi Mani,

Commands look right to me except that you will have to shutdowm p1 before removing cell 3 from it.
Also I'd caution you to verify that the I/O chassis is *not* connected to cell 3 because if it is you'll lose all I/O in p1

Hi Mani,

We cant remove a cell from a partition which is active.

Hence pls do,

in PARTITION 1

#parmodify -p1 -m 3:base:n:ri

#shutdown -R

after reboot the P1 will have only 2 cells.


in PARTITION 2

#shutdown -R -H

This will force the cell in P2 to BIB state.

NOw run the below from P1,

#parmodify -p2 -a3:base:y:ri

after the reboot, the P2 will have cell3 added to that.

Regards,

Siva.

hello siva,
How are you?


ok.. You meant to say that we have to deactivate the cell board being booting and rendezvous to the active partion. But do you think deactivating the partition , will remove the configuration from the active partion.

what will happen if i do like this.

Partition 1:

#parmodify -p1 -m3:base:n:ri
#shutdown -R
#parmodify -p1 -d3 (===>this is to delete from the partition config)

#shutdown -R

partition 2:
#shutdown -R -H

partition 1:

#parmodify -p2 -a3:base:y:ri


at last boot the partion 2.

regards,
Mani

Hi Mani,

YES ! you are right.

This is required to remove the cell3 from P1, before adding to P2. At any point of time to do any modification in cell config wrt partitions, the cell needs to be in BIB/inactive.

So..

#parmodify -p1 -d3 (===>this is to delete from the partition config

is required..

by the way, thanks for the regards. Im fine. How about you?

Best Regards,

Siva.

Hi Siva,

I am fine , thank u./

one more doupt.. do i need to reboot twice..
one after doing " -m3:base:n:ri "
and then after doing " -d3"

thanks ,

Mani

Dear Mani,

NO, Deletion of inactive cells does not require a shutdown of the partition.

So, ONE reboot is sufficent.
