I received two replies, one from Bob Vance and one from Angelo Collazo.
Bob Vance said that this happens when encountering an automounter directory.
I killed automounter before starting copy, I'm not sure if it matters or
not.
Angelo Collazo suggested using the any of the following which worked for
him.
# find /old_directory -depth | cpio -pdmv /new_directory
% cd <source-directory>
% find . -depth -print | cpio -pudm <dest-directory>
cd /path/to/src/dir
find . | cpio -pdumv /path/to/dest/dir
cd SOURCE_DIRECTORY.
find . -depth -xdev -print | cpio -padmv
{TARGET_DIRECTORY_NAME_HERE}
The command I used is very similar, just a few switch changes, not sure why
they'd work on one box and not another. I will try to do all of them (until
I get a winner) when I get approved downtime again.
Thanks to Bob Vance and Angelo Collazo

Subject: [HPADM]: Command hangs while performing "find" into "cpio"
Hello HP Admins:
SYSTEM: C240+, HP-UX 10.20
While manually refreshing the data on a duplicate of the root disks Logical
Volumes, I ran into a problem where the "find piped into cpio" command
froze/hung, and no further copying of data occurs. I'm trying to get some
ideas as to why this happened...
Here's some info in more detail:
ROOT DISK LV's Mount Point EXTERNAL DISK LV's
/dev/vg00/lvol3 / /dev/vgroot/root
/dev/vg00/lvol1 /stand /dev/vgroot/boot
/dev/vg00/lvol9 /var /dev/vgroot/lvol9
/dev/vg00/lvol7 /usr /dev/vgroot/lvol7
/dev/vg00/lvol8 /usr/local /dev/vgroot/lvol8
/dev/vg00/lvol6 /tmp /dev/vgroot/lvol6
/dev/vg00/lvol5 /opt /dev/vgroot/lvol5
/dev/vg00/lvol4 /genesis /dev/vgroot/lvol4
Here's the process I was performing in more detail:
I manually mount an individual partition: "mount dev/vgroot/lvol9
/mnt";
Verify that I'm seeing what I'm supposed to be seeing: "bdf -l | grep /mnt"
Then "cd /mnt" to the mount point and then "pwd" to verify location;
Then I wipe out the data with "rm -r * ", and then "ls -al" to verify it's
all gone;
Then "cd /var", verify with a "pwd";
Then "find . -xdev -depth -print | cpio -pxdmv /mnt".
BTW, this only happened when copying the "/var" directory trees. When the
copy gets to /var/tmp it hangs at certain files. So I went and deleted these
files (zero length) and I still have the hanging issues. I can "Ctrl C" out
of the copy, but if I don't it just hangs there indefinitely. It does copy
about 90% of the data in /var to my external disks logical volume but not
the total source data like the other LV's.
Any ideas out there on what might be wrong here??? I will summarize!
Thanks in advance,
