Thanks to Mark Olson, mark_olson@adc.com, who gives me the right answer.
"Add the vers=2 to the cachefs mount entry".

I also found on SunSolve that this is a known issue.
FAQ ID 2217:Empty "dir" when mounting huge filesystems from 2.6 NFS servers.
The solution is the same.

My original question and Mark's email are followed.

Add the vers=2 parameter to the mount entry, here is the line
from my 2.5.1 system's /etc/auto_direct file, the server nfs5900
is running Solaris 2.6

/usr/local -intr,fstype=cachefs,vers=2,backfstype=nfs,cachedir=/files/cache
nfs5900:/vol01/tools/local.sol2.sparc

HTH,
Mark
