Hi,
There is no need to delete existing shares on SVM 'B1'. In cDOT you can use 'netbios' feature to add 'netbioses' to existing SVM.
As I understand your scenario:
7-mode vfiler = A1
cDOT vserve = B1
After migrating CIFS shares from A1 to B1, you can simply add 'A1' as netbios alias to 'B1' and stop the old CIFS service.
Steps:
Pre-requisite: enable these two options:
::> set adv [Go to advanced mode]
::*> vserver cifs options modify -vserver B1 -is-nbns-enabled true
::*> vserver cifs options modify -vserver B1 -is-netbios-over-tcp-enabled true
1) First check if there is already any existing netbios-aliases for the given vserver:
::> vserver cifs show -vserver B1 -fields netbios-aliases
2) Now, add old CIFS server as netbios to the 'B1'.
::> vserver cifs add-netbios-aliases -vserver B1 -netbios-aliases A1
3) Verify if it is added:
::> vserver cifs show -vserver B1 -fields netbios-aliases
Wait for couple of minutes...
open Windows command prompt and ping added netbios:
C:\Users\Administrator>ping A1
4) Next thing, you need to make sure 'SPN' is set correctly otherwise 'kerberos' will break and users will login via NTLM security.
Have a user, who is a member of Domain Admins, run the following from a command prompt: Set SPN for A1 (7-mode cifs) to B1 (cdot cifs):
WIndows promt:
setspn.exe -S HOST/A1.domain.com B1
setspn.exe -S HOST/A1 B1
To verify: [A1 should be seen added]
setspn -L B1
5) If you could (possible) then bounce the vserver.
::> vserver cifs stop -vserver B1
::> vserver cifs start -vserver B1
6) Access the CIFS shares via \\A1
7) check the 'auth-mechanism' it should say 'kerberos' if it is using Active Directory authentication or it will be NTLM. Anyway this is additional information I thought its worth sharing.
::> cifs session show -vserver B1 -fields auth-mechanism
Thanks!
(I did this on 9.1, but it should apply to 9.5 as well, rest you can figure it out)
