VNX CIFS migration issues
Hi.
I am trying to migrate a CIFS server from a VNX5600 to Unity 300.
Created new vdm for test.
VNX VDM Name: vdm02
New CIFS server, file system and shares
After creating a connection on the Unity this VDM shows up in the session list as vdm02. Migration works fine and completes. This also worked for another vdm named vdmtest.
When it comes to migrating the production CIFS server I get the following issues.
VNX VDM Name: vdm01
After creating a connection on the Unity this VDM shows up in the session list as vdm01_1 (nfs)
Created another vdm.
VNX VDM Name: vdm01_1
After creating a connection on the Unity this VDM shows up in the session list as vdm01_1_1 (nfs)
I cannot get vdm01 to show up as a CIFS source or even get the name correct.
I have followed the requirements from the documentation.
I've checked the differing vdms and CIFS servers and can see no differences.
Ideas?

I would suggest to open a service request
In my experience this needs log file to be looked at
Unity OE 4.2.2 just got released - It might be worth to try it or at least look at the release notes if something related is fixed there

Thanks. I already did that. I'm awaiting assignment as it's low severity. Read the Release notes.

yes - that would be a common mistake since on VNX you didnt have to attach the interface to a VDM unless you were doing NFS export via VDM

That was the problem.
[nasadmin@v340cs01 ~]$ nas_server -info -v vdm01
id = 1
name = vdm01
acl = 0
type = vdm
server = server_2
rootfs = root_fs_vdm_vdm01_1
I18N mode = UNICODE
Thank you.
Hello,
Hello,
I have almost the same problem.
Unisphere shows the VDM as "NFS" instead of "CIFS"
here are the parameters of the VDM
id = 1
name = VDM01
acl = 0
type = vdm
server = server_2
rootfs = root_fs_vdm_VDM01
I18N mode = UNICODE
defined = enabled
actual = loaded, active
Interfaces to services mapping:
interface=nas_migration_VDM01 :cifs
interface=int_vdm02 :vdmThank you very much for your help.
Best regards
hi clignel,
how to add nas_migration port to VDM
id = 1
name = VDM01
acl = 0
type = vdm
server = server_2
rootfs = root_fs_vdm_VDM01
I18N mode = UNICODE
defined = enabled
actual = loaded, active
Interfaces to services mapping:
interface=nas_migration_VDM01 :cifs
interface=int_vdm02 :vdm <---------------this port.and how to add this interface to sub domain?is it required to create subdomain in domain controller?
hi all,
am also facing issue with vnx to unity migration.
i want know one thing.this below interface should be physical or virtual?
nas_migration_xx interface
below steps i followed but failed
below steps i followed.
requireed cifs perameters also changed in vnx
01.DNS and NTP sync between vnx to unity xt
02.enabled local admin in vnx
server_cifs -add compname= ,domain= ,local_users
03.Create nas migration port
[nasadmin@VNX5400 ~]$ server_ifconfig server_2 -create -Device cge-1-1 -name nas_migration_vnx5400 -protocol IP 10.10.10.10 255.255.255.0 10.10.10.1
04.Interface attached to the VDM
[nasadmin@VNX5400 ~]$ nas_server -vdm vdm11 –attach nas_migration_vnx5400
05.Create subdomain entry for nas_migration interface
[nasadmin@VNX5400 ~]$ server_cifs vdm-1 -add compname=test,domain=test.lk,interface=nas_migration_vnx5400,dns=vnx.migration.test.lk
from unity
01 crated import interfaces with two ips(spa and spb)
02 created import connection

Please check the below KB:
Dell EMC Unity : VDM Import failing to create, Reporting CIFS VDM incorrectly as NFS VDM (User Correctable) https://support.emc.com/kb/514379
If even after re-naming the VDM, in Unity while importing if it gives any error like "nas_migration_XX interface isn't attached", please check if the CIFS server's interface on the VDM is attached to VDM along with nas_migration_XX interface:
$ nas_server -info -vdm
Interfaces to services mapping:
interface=FSN1_102 :cifs <<<<<
interface=nas_migration_002 :nfs <<<<<<
Hope it helps.
