NFSv4 on Netapp and Redhat 5.3 as Client
Hi Folks!
I'm new in using NFSv4 and do have a little trouble. I had a partition working with NFSv3, at the beginning i couldn't see on the client the German umlauts letters {ö,ä,ü} a manipulation of the LANG environment variable helped and the filenames with this letters were shown normally (before the letter was replaced by an "?"). That all worked fine until we wanted to use NFSv4. The problem with the umlauts is back again. But this time it is not a "?" by that they are replaced. Every umlaut is replaced by "~#seq.Nr" and the rest of the word is cut of.
I have read that the Server and the Client hve to use the same charset, so we changed the charset on the NetApp to de_DE.UTF-8 and the Redhat to LANG=de.UTF-8. Unfortunately it didn't changed anything.
I am very thanfull for all your helps, that i can read my regular filenames again without this replacements und cut-off.
I tried several hours to find a good solution, e.g. I'm not really interessted in renaming the whole system tree. Because it would be a lot of lines to manipulate.
Kind Regards and Thank you for your help

I have this problem when i integrate a new san switch in DFM 3.01 R1 :

switchname2 is a similar san switch but in another fabric, switchname2 is already integrated in DFM database.

nfs4mapid
NFS4MAPID(8) BSD System Manager's Manual NFS4MAPID(8)
NAME
nfs4mapid -- shows NFSv4 mappings from uids or gids to over the wire string names and string names to uids or gids.
SYNOPSIS
nfs4mapid [-G] string name
nfs4mapid [-G] GUID
nfs4mapid -u uid
nfs4mapid -g gid
DESCRIPTION
In the first form, nfs4mapid shows translations from NFSv4 string representations of users, and with the -G option, groups, to the corre-
sponding local uids and gids. In the second form shows the translations from opendirectoy GUIDS to NFSv4 strings. The well known strings
names (which are distinguished by a trailing '@' ), such as "OWNER@" and "GROUP@" are represented locally by GUIDs and may not map to uids or
gids. To map those GUIDS to NFSv4 strings use this form. The first form can be used to map the well known ids to GUIDs. nfs4mapid does this
by looking at the trailing '@' sign. Note that NFSv4 well known names are always groups and are used in ACEs. In the third form, it shows
the mapping from uids to the NFSv4 user@domain form. Similarly, in the last form it shows the mapping from gids to the NFSv4 group@domain.
nfs4mapid will also show the intermediate GUID translation if used. The NFSv4 domain name should be set with dscl(1). See opendirectory(8)
for instructions.
-G Map an NFSv4 string to a gid.
-u Map a uid to an NFSv4 user@domain string.
-g Map a gid to an NFSv4 group@domain string.
NOTES
nfs4mapid uses a privileged nfs client system call to pass the translation request down to the kernel, so results will be the same as a
request coming from an NFSv4 server. Because of this, nfs4mapid must be run with root privileges.
