problem in executing cp and chgrp command

[madhucertify]

Hi

NAS model : vnx 7.1

os version : Red hat Linux 4.4

we performed the NAS microcode upgrade .

after upgrading,we faced the below issue.

for example

when I copy a file name "test1.file"

---------------------------------------------------------

rw- rw- rw userA  admin  test1.file

----------------------------------------------------------

i am login to the server with my individual account , userB and I am executing

cp -ip test1.file /home/userB

after executing copy command, owner getting changed automatically.

instead of owner to be remained  as userA and admin,

 owner getting changed automatically to userB and userB.

what could be the issue ???

we tested for other mount points (for internal disk and SAN mount point),there are no issue.

problem only is with NAS mount point.

is that problem with OS or NAS ?

Hi

1.Is there any version for NAS file system ?

 example,for SAN mount point we use VXVM.

Do we have any version for NAS filesystem ??
