Where are you running this command, I am guessing on the LPAR, but just to check that you have not got any VIO in there too.
What MPIO device driver are you using, most EMC shops use POWERPATH to enable load_balance to be used allowing the bandwidth of all HBA adapters to be used, just make sure you license it as EMC do charge for this.
If you are uisng POWERPATH then the command is not correct, I think the attribute is reserve_lock=no you need to set.
If you are using EMC disks and the default MPIO then I would expect you will need the ODM filesets anyway to allow AIX to identify the disks, anybody using this mechanism that can confirm as I have only used POWERPATH before? I would suggest that you get hold of the ODM filesets if this is the case and then install, reboot and retry.
Of course it may be as simple as the other box booted first and has hold of the disk and you just need to run the command on the other node...
