kah00na, Does the live dump function still work OK on the JFS2 FS, or was this something you did for a laugh that will come back and haunt you in the future?
As for hd11admin:
http://www.redbooks.ibm.com/redpieces/pdfs/sg247559.pdf
Beginning with AIX V6.1 the operating system provides a dedicated system
directory /admin/tmp where privileged processes can securely create temporary
files. The /admin/tmp directory resides within the /admin file system which in turn
is defined on the newly implemented /dev/hd11admin system logical volume. You
can use the standard ls, lsfs, and lslv AIX commands to list the properties of
the directory, mount point, file system, and logical volume respectively
