So, what could be the problem ?

Thanks.

Code:
rc=1
0042-001 m_mkbosi: processing error encountered on "master":
   0042-175 c_getlevel: An unexpected result was returned by the "/usr/lpp/bos.sysmgt/nim/methods/c_stat" c

While you try with eznim it tries to take mksysb in "/export/eznim/mksysb/bcoeqa_sysb" which is not present in your server.

While you are trying with command line this error should not come because you are using location=/nimfs/mksysb.bcoeqa mksysb_bcoeqa check whether /nimfs is exported to all your nim_clients.

Thanks for the prompt reply:

I am getting the same error with the CLI command line
nim -o define -t mksysb -a server=master -a source=bcoeqa -a mk_image=yes -a location=/nimfs/mksysb.bcoeqa mksysb_bcoeqa


I don't have to manually export /nimfs by NFS to all my clients ? because NIM is suppose to take care of it.

POSTSCRIPT

After re-installing, NIM it worked fine. I don't know why the errors appeared although I followed the same procedure.

Thanks

Most likely the error stems from having exported parts or even a superset of the NIM directories by hand. NIM is pretty picky about these things, for reasons unknown.

Here is an example:

Your NIM resource in question resides in "/some/where/resource". If you use it in a NIM operation this directory will become exported in "/etc/exports" automatically by NIM. Suppose you manually export "/some/where" to world now. Chances are NIM will generate an error even if the manual (and more generous) export should do no harm to the subset being exported to a specific host alone.

Bottom line: before using NIM remove all exports of the directory hierarchy NIM uses completely, then run "exportfs -va" to make sure NFS knows about that.

I hope this helps.

OK,
let me try again:

Code:
# egrep "bootpd|tftpd" /etc/inetd.conf
bootps  dgram   udp     wait    root    /usr/sbin/bootpd       bootpd /etc/bootptab
tftp     dgram  udp6    SRC     nobody  /usr/sbin/tftpd         tftpd -n
#

# lssrc -s tftpd
Subsystem         Group            PID          Status
 tftpd            tcpip            295058       active
# lssrc -l -s inetd|grep bootpd
 bootps       /usr/sbin/bootpd         bootpd /etc/bootptab     active

My objective:

1) Client "clonebco" should pull the makesysb from NIM Server

2) I went to client clonebco --> started SMS --> IPL --> IP address settings -- (Was able to ping NIM Server )

3) NIM Server Config so that the client is ready to pull the mksysb

When I check the client I get 
Bootp failed !
but when I ping from NIM Server to my client, I can see on my client's screen ICMP 8: Ping request
 
doesn't work.... someone mentioned to me that I shouldn't have any DHCP servers because NIM will be acting as one. is it true ?

Yes and no: NIM uses an older predecessor of DHCP, which is called bootp. DHCP is actually a superset of bootp and uses the same mechanisms and protocols as bootp, but the IP adresses the DHCP server gives out can be selected from a pool of available ones, while a bootp server only maintains a 1:1 relationship of hosts and IP adresses. There are other differences too, but this is the most prominent one. See for details RFC1533 and RFC1534.

So, yes, a DHCP server is able to confuse bootp clients, depending on the circumstances.

I hope this helps.

I disabled the windows DHCP server but still the client can't pull the O/S from NIM Server.

Able to ping successfully.
