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 :
dfm fcswitch add switchname1
Error: Host switchname2 (11197) already exists.
switchname2 is a similar san switch but in another fabric, switchname2 is already integrated in DFM database.

rpc.idmapd
RPC.IDMAPD(8) BSD System Manager's Manual RPC.IDMAPD(8)
NAME
rpc.idmapd -- NFSv4 ID <-> Name Mapper
SYNOPSIS
rpc.idmapd [-v] [-f] [-d domain] [-p path] [-U username] [-G groupname] [-c path]
DESCRIPTION
rpc.idmapd is the NFSv4 ID <-> name mapping daemon. It provides functionality to the NFSv4 kernel client and server, to which it communi-
cates via upcalls, by translating user and group IDs to names, and vice versa.
The options are as follows:
-v Increases the verbosity level (can be specified multiple times).
-f Runs rpc.idmapd in the foreground and prints all output to the terminal.
-d domain Set domain to domain. This is used internally by NFSv4 and is typically assigned by the system administrator. By default,
domain is set to be the FQDN of the host, minus the hostname.
-p path Specifies the location of the RPC pipefs to be path. The default value is "/var/lib/nfs/rpc_pipefs".
-U username Specifies the NFSv4 nobody user to be username. The default value is "nobody".
-G groupname
Specifies the NFSv4 nobody group to be groupname. The default value is "nobody".
-c path Use configuration file path.
-C Client-only: perform no idmapping for any NFS server, even if one is detected.
-S Server-only: perform no idmapping for any NFS client, even if one is detected.
EXAMPLES
rpc.idmapd -d "citi.umich.edu" -f -vvv
Runs rpc.idmapd with the domain "citi.umich.edu" in the foreground, printing all messages to console, and with a verbosity level of 3.
