Thanks for your tips

Try smaller steps. Can you do
# rmdev -dl rmt0
?

thanks for the reply shockneck

I remove the device but when I try to move dynamic to my lpar that I want that have now the device. I do all this from the HMC.

I got a message. That I cant remove and device. even If I want to remove dynamic the device I got the same message.

The whole picture is this.

1.-I have to remove the device from the command line
2.-I have to move from my lpar that got the device to the new lpar that I get to put, all this dynamic
3.-I have to run cfgmgr
4.-Verify that I got the device from the command line.

The step one theory I done. That´s why I put the out of the command lsslot -c slot because I still got on that partition.



Thanks again for your tips

Yes, but from the first error message you did not know which device AIX considers being busy. Now you know that it was not the rmt0 device. Run cfgmgr to get rmt0 back and then identify any device in the device tree of rmt0. Use
# lsdev -l <device> -F parent
for any device beginning from rmt0 till you end up at the slot and try to rmdev any device manually to identify the device which AIX considers being busy.

Secondly check that in the lpar's profile the slot is defined as optional (not required) to be fit for DLPARing. You need to stop and activate the LPAR to change this.
