can't mount the cdrom in AIX 5.2

[21sam]

Hi,
can anyone help to overcome this problem?
i am running LPAR'S in p650. the cdrom drive is working properly in other lpar's except one lpar.
in lsdev- it shows device is defined but not available.
how can i make it to available?
during this process i am getting a error message says

method error: /etc/methods/cfgsccd
0514-028 -cannot perform the reguested function because the parent of the specified device is not in correct state.

please help me to overcome this problem..
advance thanks for replies

in a lpared env, any specific device is only 'available' in one lpar at a time. You have to use dlpar procedures to move around the parent adapter from one lpar to the other.

You need to undefine the device and its parents up to the pciXX device on the lpar that has the cdrom.

First you have to find out which pci slot/adapter is the parent for your device.
To find the slot/adapter, use the command lscfg:

example:

lscfg|more
...
* pci24       U1.9-P1                                       PCI Bus
+ scsi0       U1.9-P1-I10/Z1                                Wide/Ultra-3 SCSI I/O Controller
+ cd0         U1.9-P1-I10/Z1-A1                             16 Bit LVD SCSI DVD-ROM Drive (4700 MB)
...

Here the adapter which has cd0 as child device is in slot "U1.9-P1-I10"

Once you know this, you can unconfigure all devices on this slot on the LPAR that has the device(s)

rmdev -Rdl pciXX

In my example it would be pci24. Yours will be different!

Then on the HMC, move the named slot/adapter to the other LPAR and run a cfgmgr on the destination LPAR. Then you can access the device on that LPAR.
