Moving Vfiler from one filer to another

Pre-requisite:

                 Required checklist info to implement changes

                                     To move vfiler  

·         Filer name

·         Aggregate name

·         Make sure to setup DR replications after moving vfiler to new filer?

 Start replicating volumes:

 (Example: we are moving labvfilerfrom lafiler1 to labfiler3. Here labfiler1 DR is labdrfiler1 and labfiler3 DR is labdrfiler3)

1.       ssh to labfiler1 to get volume info for labvfiler

labfiler1>  vfiler status -r labvfiler

labvfiler                       running

   ipspace: vfilers1

   IP address: 10.10.1.2 [vif1-110]

   Path: /vol/labvfiler [/etc]

   Path: /vol/labvfiler_vol1

   Path: /vol/labvfiler_vol2

   Path: /vol/labvfiler_vol3

   Path: /vol/labvfiler_vol4

   UUID: 2a0000d6-4594-1ew1-9e2f-007891w2fc3

labfiler1> vol size labvfiler

Warning: Volume 'labvfiler' has fs_size_fixed option set.  The file system

size may differ from the volume size.

See 'vol status -b' for more detail.

vol size: Flexible volume 'labvfiler' has size 5g.

labfiler1> vol size labvfiler_vol1

vol size: Flexible volume 'labvfiler_vol1' has size 2202g.

labfiler1> vol size labvfiler_vol2

vol size: Flexible volume 'labvfiler_vol2' has size 1975g.

labfiler1> vol size labvfiler_vol3

vol size: Flexible volume 'labvfiler_vol3' has size 1714g.

labfiler1> vol size labvfiler_vol4

vol size: Flexible volume 'labvfiler_vol4' has size 3319g. 

2.       Once you collect volume info, ssh to labfiler3 and check on which aggregate has enough space

3.       Create NEW volumes on labfiler3 and start replicating

Ø  vol create volumename –s none aggrname XXXg

Ø  vol restrict volumename

Ø  snapmirror initialize –S source:volumename destination:volumename

labfiler3> vol create labvfiler -s none aggr0 5g

Creation of volume 'labvfiler' with size 5g on containing aggregate

'aggr0' has completed.

labfiler3> vol create labvfiler_vol1 -s none aggr0 2202g

Creation of volume 'labvfiler_vol1' with size 2202g on containing aggregate

'aggr0' has completed.

labfiler3> vol create labvfiler_vol2 -s none aggr0 1975g

Creation of volume 'labvfiler_vol2' with size 1975g on containing aggregate

'aggr0' has completed.

labfiler3> vol create labvfiler_vol3 -s none aggr0 1714g

Creation of volume 'labvfiler_vol3' with size 1714g on containing aggregate

'aggr0' has completed.

labfiler3> vol create labvfiler_vol4 -s none aggr0 3319g

Creation of volume 'labvfiler_vol4' with size 3319g on containing aggregate

labfiler3> vol restrict labvfiler

Volume 'labvfiler' is now restricted.

labfiler3> vol restrict labvfiler_vol1

Volume 'labvfiler_vol1' is now restricted.

labfiler3> vol restrict labvfiler_vol2

Volume 'labvfiler_vol2' is now restricted.

labfiler3> vol restrict labvfiler_vol3

Volume 'labvfiler_vol3' is now restricted.

labfiler3> vol restrict labvfiler_vol4

Volume 'labvfiler_vol4' is now restricted.

labfiler3> snapmirror initialize -S labfiler1.rr.snd.com:labvfiler labfiler3:labvfiler

Transfer started.

Monitor progress with 'snapmirror status' or the snapmirror log.

labfiler3> snapmirror initialize -S labfiler1.rr.snd.com:labvfiler_vol1 labfiler3:labvfiler_vol1

Transfer started.

Monitor progress with 'snapmirror status' or the snapmirror log.

labfiler3> snapmirror initialize -S labfiler1.rr.snd.com:labvfiler_vol2 labfiler3:labvfiler_vol2

Transfer started.

Monitor progress with 'snapmirror status' or the snapmirror log.

labfiler3> snapmirror initialize -S labfiler1.rr.snd.com:labvfiler_vol3 labfiler3:labvfiler_vol3

Transfer started.

Monitor progress with 'snapmirror status' or the snapmirror log.

labfiler3> snapmirror initialize -S labfiler1.rr.snd.com:labvfiler_vol4 labfiler3:labvfiler_vol4

Transfer started.

Monitor progress with 'snapmirror status' or the snapmirror log. 

4.       Update snapmirror.conf with scheduling depends on cutover/move date

5.       As labfiler3 d2d is labdrfiler3, we have to replicate all volume from labfiler3 to labdrfiler3.

Create same volumes on labdrfiler3 and start snapmirror initialize once labfiler1 to labfiler3 base transfer completes. Here we can also start copying from labdrfiler1 to labdrfiler3
