I am able to perform DLPAR operations to move cdrom drive from one lpar to another lpar, but in some cases, when I run cfgmgr on the destination lpar, the cdrom drive does not show up. I can see the slot and the ide0 device, but cd0 does not show up unless I reboot the lpar. This is not always possible.

Any ideas anyone?

Any help is very much appreciated.

There was a similar question in the virtualization forum. You might check out that thread to see if it has any info that helps.

Not sure what steps you are taking but here are the steps I go through to move around a shared CD-rom and have never run into any problems.

Make sure the CDROM is in the desired state for all LPARs.
Log into the LPAR that has the CDROM allocated.
Remove the CDROM using the following AIX commands:
lsdev CF name type parent location | grep cd0
lsdev CF name type parent location | grep ide0
#Remove the parent pci# that is assign to cd0
rmdev dl pci# -R
Log into HMC and right click on the LPAR that has the cdrom.
Select Dynamic Logical Partitioning -> Physical Adapter Resources -> Move
Select CDROM Device
Select LPAR to move CDROM and press Enter.

thanks for the responses...my problem wound up being on machines where the ide1 device was already defined. for any machines with an ide1 device, i had to first remove the ide1 device, then do the cfgmgr and it would detect ide0 and then ide1, and then the cdrom would show up fine.
