How to check agblksize on AIX?

Howdy listers,  

I've seen recommendations that the agblksize should be set to 512 for AIX JFS2 filesystems mounted with CIO, when being used for the Oracle redo logs. Anyone know how to verify if a filesystem has been created with agblksize=512?  

I tried the "mount" command and lsfs -q and don't see any mention of agblksize in the output. Any other ideas?  

Thanks,
Brandon
