Moving CDROM between LPARS

MOVE A CDROM FROM ONE LPAR TO ANOTHER LPAR

MOVE A CDROM FROM ONE LPAR TO ANOTHER LPAR

CHECK THE CDROM ON THE PARENT LPAR

this document will give you detail idea about step by step moving a cdrom from one lpar to another dynamically  in a P5 box

We need to know first what is the physical location of cdrom , or we should be knowing what type of adapter cdrom is connected to for example other "mass storage adapter"
If we go to the properties of the box in hmc we can see all the adapters that the box have and to which lpar that adapter is currently assigned  , hence we can know currently which lpar is holding the cdrom



 Check the cdrom and I/O adaper providing the cdrom . Check the physical location of I/O

adapter providing the cdrom

# lsdev -l cd0 -F parent

scsi1

# lsdev -l scsi1 -F parent

sisscsia0

# lsdev -l sisscsia0 -F physloc

U789D.001.DQD07P3-P1-C4

# lsdev -l scsi1 -F physloc

U789D.001.DQD07P3-P1-C4-T2

REMOVE THE CDROM FROM THE LPAR

Note the physical address of adapter in the above command

# rmdev -dl cd0

cd0 deleted

MOVING THE ADAPTER

Goto Properties of the magaged machine to view all the adapters

Select I/O adapters and see the physical address of the adapter This should match with the physical location of the adapter which we deleted in the previous step

The physical location marked in the above figure shows which lpar is using that adapter currently


Go to lpar  >> select the link besides the lpar  >> select Dynamic lpar >>Physical Adapters >> Move or remove

Select the adapter and click on to remove or select the partition from "Move to partition option" to move directly to the destination partition

With the help of physical address determined above go to the properties of the managed

system and veryfy the I/O adapter

If you are facing the same error as I faced below go to the parent lpar and delete the

parent adapter of the cdrom (the adapter you want to move has to be deleted from the

parent lpar )

DELETE THE ADAPTER

# rmdev -Rdl sisscsia0

rmt0 deleted

scsi0 deleted

scsi1 deleted

sisscsia0 deleted

VERIFY ON THE TARGET LPAR

Go to the terminal console of the target lpar and verify that the cdrom is now moved

Verify the adapter by physical location
