7 to C Migration Methods for SnapMirrored 7-Mode Volumes: Part 5/7


Part 5) Method 2: Using 7MTT CLI Wizard to Migrate Our 7 to 7 SnapMirror Relationship

We revert the lab to the state at the end of Part 3.

Note: This part is a bit long since it contains a lot of the screen output (slightly abridged for presentation purposes.)

7MTT CLI: Session for the SnapMirror secondary - NAFAS2 - migrating to NASVM2

Step: Main menu
===============
Select one of the following menu items:
1. Show all sessions
2. Create a new session
3. Select existing session
4. Exit
Enter your selection(1-4): 2

Help to select a session type:
standalone - transitioning volumes that are not in data-protection relationship, or data-protection relationship should be ignored during transition.
primary - transitioning volumes that are the source of a data-protection relationship.
secondary - transitioning volumes that are the destination of a data-protection relationship and these volumes be transitioned before the primary volumes.
Select the type of the session {primary, secondary, standalone} [standalone]: secondary

Step: Select the 7-Mode storage system
======================================
You can type 'back', 'exit', 'help' or '?' at any time.

Enter the FQDN or IP address of the secondary 7-Mode system: NAFAS2.lab.priv
Enter the administrative user-name for the secondary 7-Mode system 'NAFAS2.lab.priv' [root]:
Enter the password for 'root@NAFAS2.lab.priv':
Enter the SnapMirror source data copy IPv4 address : 10.10.10.201

Specifying another IP address of the 7-Mode system enables data copy to proceed over more than one physical path. The copy process uses both paths at the same time, therefore, load balancing the data transfers. The primary IP address must be always available; otherwise the data copy fails and does not continue by using the alternate IP address. Enter another IP address for setting up multipath to the 7-Mode system(Press 'Enter' to skip):

INFO: This session is saved under the temporary name: 'Session_20140504_173833'.

Step: Select 7-Mode volumes
===========================
Retrieving volume information from 7-Mode system 'vfiler0@NAFAS2'
Found 4 volumes that are candidates for transition on the 7-Mode system 'vfiler0@NAFAS2':
VolumeName Size   Used(%) Snapmirror
---------- ----   ------  ----------
vol2       2.00GB     5%  secondary
vol1       2.00GB     5%  secondary
vol0       3.30GB    13%  -
vol3       2.00GB     5%  secondary

Enter the comma separated list of volumes for transition: vol1,vol2,vol3

You selected 3 volume(s):
VolumeName Size   Used(%) Snapmirror
---------- ----   ------- ----------
vol1       2.00GB     5%  secondary
vol2       2.00GB     5%  secondary
vol3       2.00GB     5%  secondary

Confirm your selection: yes

Step: Run precheck
==================
Provide a name for this session [Session_20140504_173833]:
Do you want to run precheck on the session: yes

Verify feasibility of transition - Check if all the features and functionality included in this session is supported in Cluster-Mode.

Next suggested steps:
---------------------
1. Use the 'transition job-results -j 3c560d76-df81-449d-bdd7-722b3b392392' command to see the results of this operation.
2. Carefully review the precheck operation results before proceeding with the next step.

Step: Select target cluster

In this step, you can select a Vserver from the list of existing Vservers in the cluster or provide information about a new Vserver, which will be created by the 'transition start' operation.

Retrieving Vserver information from the cluster 'NACLU2'

Vserver   Root volume   State
-------   -----------   -----
NASVM2    rootvol       running

Select an existing 'data' Vserver or enter a new Vserver name that must be created during 'transition start' operation: NASVM2

Step: Configure target volumes
==============================
Retrieving aggregate information from the Cluster 'NACLU2'

Found 1 online aggregate(s) on this cluster:

Step: Start the cutover operation
=================================
Do you want to run the complete (cut-over) operation on this session? YES

This complete operation can be run in either of the following two modes.

Test mode: If you select test mode, all the 7-Mode IP addresses and volumes added to the session are not modified in any way. All the client applications can continue to access data from the 7-Mode storage system after the complete operation. All the LIFs added to the session will be created on the Vserver in the 'down' state.

Normal mode: If you select normal mode, all the 7-Mode IP addresses added to the session will be unconfigured on the 7-Mode storage system and created on the Vserver in the 'up' state. All the 7-Mode volumes added to the session are made offline.

Select the mode in which you want to run this complete operation {normal, test}: normal

Next suggested steps:
---------------------
1. Use the 'transition job-results -j 365e97e4-2d25-4912-a293-3715b2404d1c' command to see the results of this operation.
2. Review results of the complete operation before enabling client access.

Note: One thing I noticed later on was “7/8: Establishing relations between the 7-Mode primary and Cluster-Mode secondary...” I might have missed a step since these were left in place after I’d cutover the primary. You’d have this relationship to make sure the secondary has a copy of the latest data (and the all-important ‘in-common’ snapshot so the C to C relationship can be re-synced.) Using the next method - 7MTT CLI commands - we don’t have this problem.

7MTT CLI: Cutover NAFAS1 to NASVM1

On MSADM1, disconnect CIFS shares U, V and W:

net use U: /delete
net use V: /delete
net use W: /delete

On NAFAS1, run these commands:

priv set advanced
cifs terminate -v vol1
cifs terminate -v vol2
cifs terminate -v vol3

MSDMC01: Update the CNAME for FS1 to point to NASVM1

Update the CNAME FS1 (which pointed to NANAS1.lab.priv) to point to NASVM1.lab.priv.

MSADM01: Remount the shares and test data access

ipconfig /flushdns
net use U: \\FS1\share1 /persistent:yes
net use V: \\FS1\share2 /persistent:yes
net use W: \\FS1\share3 /persistent:yes

Cutover complete!

Complete tidy up tasks as required.

Note: I might have missed a step! The snapmirror relations from primary to secondary Cluster-Mode volumes were not in place after the cutover (Part 7 details creating these.) Using the next method - 7MTT CLI commands - we don’t have this problem.
