: VFILER
Hi ,
VFILER 0 is physichal filer so you can start with vfiler 1 to 2
- Vfiler DR fas6080b_vfiler1 from simulator node fas6080b to both fas6080a and fas3170
FAS6080B to FAS6080A DR Vfiler
• fas6080a> vfiler status -a
• fas6080a> vfiler dr configure -c secure -l root:netapp fas6080b_vfiler1@192.168.150.101
o keep the same IP address and subnet (you can change for DR)
o keep the same DNS (you can change for DR)
o use “ns1” interface on the dr vfiler
• fas6080a> vfiler dr status fas6080b_vfiler1@192.168.150.101
• fas6080a> snapmirror status
• fas6080a> vfiler status -a
FAS6080B to FAS3170 DR Vfiler (to have more than 1 DR target) – use “-s” option for snapmirror sync
(ignore “too many active transfers at once errors” from the simulator)
• fas3170> vfiler status -a • fas3170> vfiler dr configure -s -c secure -l root:netapp fas6080b_vfiler1@192.168.150.101
o enter nothing for “alternate
o keep the same IP address and subnet (you can change for DR)
o keep the same DNS (you can change for DR)
o use “ns1” interface on the dr vfiler
• fas3170> vfiler dr status fas6080b_vfiler1@192.168.150.101
• fas3170> snapmirror status
• fas3170> vfiler status -a
• Delete the DR vfiler (this was an example to create two, but for the lab we will failover locally
to the FAS6080A node.)… the volumes will still be available to vfiler0.
o fas3170> vfiler dr delete fas6080b_vfiler1@192.168.150.101
o fas3170> vfiler status -a
FAS6080B_vfiler1 will be shut down to simulate a disaster and FAS6080A_vfiler1 DR will be brought
online (STOP on node B and dr on node A) *** NOTE THE FILER NAMES TO ISSUE COMMANDS ***
• fas6080b> vfiler stop fas6080b_vfiler1
• fas6080a> vfiler dr activate fas6080b_vfiler1@192.168.150.101
• fas6080b> vfiler status -a # confirm fas6080b_vfiler1 is stopped
• fas6080a> vfiler status -a # confirm fas6080b_vfiler1 is running
• Confirm CIFS, NFS and iSCSI access is uninterrupted for fas6080b_vfiler1 (note: the point of this lab
is not to show no interruption since it is a DR event which will often be a different physical location
with different IPs, etc.).

then resync back to the DR site.
• Resync the DR site from the 6080A dr node to the 6080B prod node.

ADVANCED LAB – this step must be completed to continue on with labs 6-9
- This step will show how to create a DR vfiler if mirrors already exist before vfiler DR. vfiler dr
configure initializes mirrors from scratch which may not be desired if mirrors already exist for
- volumes. This procedure will create the dr vfiler by manually creating it on the target (all mirrors
done manually) then doing a dr resync instead of a dr configure.
• Note that the “CONFIGURE” step does a level 0 mirror initialization… but what if there are already
mirrors running…it is not feasible to baseline when already initialized. Simply mirror all remaining
volumes in the source vFiler to the DR site, then create the vFiler manually on the
destination…then do a DR resync instead of using dr configure.
• Procedure
o Using the fas6080b_vfiler1 source vfiler to the FAS3170 already has mirrors running. At
a customer this might be a 10TB usable volume and you would not want to re-init with
the “vfiler dr configure” method. So, mirror remaining volumes manually and manually
create the dr vfiler, then run “vfiler dr resync” to create the destination DR vfiler.
o Mirror any remaining volumes NOT mirrored that are in the source vfiler (make sure to
use the same volumes names on source and dest) – REPEAT for ALL volumes NOT
mirrored yet
fas3170> vol restrict fas6080b_vfiler1_root
fas3170> vol restrict fas6080b_vfiler1_nas
fas3170> vol restrict fas6080b_vfiler1_san
fas3170> snapmirror initialize -S fas6080b:fas6080b_vfiler1_root
fas6080b_vfiler1_root
fas3170> snapmirror initialize -S fas6080b:fas6080b_vfiler1_nas
fas6080b_vfiler1_nas
fas3170> snapmirror initialize -S fas6080b:fas6080b_vfiler1_san
fas6080b_vfiler1_san
o Quiese and Break all mirrors on target – REPEAT for ALL volumes
fas3170> snapmirror status # wait until mirrors are initialized
fas3170> snapmirror quiesce fas6080b_vfiler1_root
fas3170> snapmirror break fas6080b_vfiler1_root
fas3170> snapmirror quiesce fas6080b_vfiler1_nas
fas3170> snapmirror break fas6080b_vfiler1_nas
fas3170> snapmirror quiesce fas6080b_vfiler1_san
fas3170> snapmirror break fas6080b_vfiler1_san
o Manually create the vfiler on the destination on the broken mirrors (you only need the
root volume of the vfiler from the source since it will pick up member volumes
automatically from the root configuration – the network will be unconfigured)
fas3170> vfiler create fas6080b_vfiler1 -r /vol/fas6080b_vfiler1_root
o Check the Status and Stop the vfiler
fas3170> vfiler status -a fas3170> vfiler stop fas6080b_vfiler1
fas3170> vfiler status -a
o If the vFiler IP Address(es) are not correct, perform the next 3 steps to add the correct IP
and remove the wrong IP….
Add .105
• fas3170> vfiler add fas6080b_vfiler1 -i 192.168.150.105
• fas3170> vfiler status -a
Remove .104
• fas3170> vfiler remove fas6080b_vfiler1 -i 192.168.150.104
• fas3170> vfiler status -a
Bring up the .105 interface so it is configured (using an alias since ns1 is
already used for fas6080a_vfiler1 with the .103 IP).. you would also edit
/etc/rc.. see below.
fas3170> ifconfig ns1 alias 192.168.150.105
fas3170> vfiler status -a # note that the interface is now configured
• Edit /etc/rc to add the ifconfig for this interface
• Optionally – use vfiler setup FAS3170> vfiler run vfilername setup -e
ns1:ip:subnet - **** NOTE: You can ifconfig a new interface or
ifconfig alias an existing interface from vfiler0, or run “vfiler run
vfilername setup -e interface:ip:subnet”. Setup will wack several
setup files (hosts, hosts.equiv, resolv.conf, exports, nsswitch.conf)
so be careful to restore from .bak if needed. Setup -e will create an
alias if the interface is already in use.
o Backup /etc/snapmirror.conf first since the file will be modified so that the mirror
schedules for the vFiler’s volumes are replicated every 3 minutes. Save the file so you
can change back to the prior schedule.
fas3170> rdfile /etc/snapmirror.conf
o Run a DR resync from source to target
fas3170> vfiler stop fas6080b_vfiler1
fas3170> vfiler status # note vfiler is stopped
fas3170> vfiler dr resync -c secure -l root:netapp
fas6080b_vfiler1@192.168.150.101
fas3170> snapmirror status
fas3170> vfiler status # note vfiler is now a dr vfiler
o Update/Fix /etc/snapmirror.conf for 3 minute interval update that was automatically
updated by resync
• Stop the DR vfiler on FAS6080B and activate the vfiler on the FAS3170
o fas6080b> vfiler stop fas6080b_vfiler1
o fas3170> vfiler dr activate fas6080b_vfiler1@192.168.150.101
o fas6080b> vfiler status -a # confirm fas6080b_vfiler1 is running
o fas3170> vfiler status -a # confirm fas6080b_vfiler1 is stopped • Halt the cluster simulator nodes since we will do the rest of the labs on the 3170
o fas6080a> halt -f
o fas6080b> halt -f
• Add the .104 IP and remove the .105 IP to match the original setup
Add .104 (it will be unconfigured)
• fas3170> vfiler add fas6080b_vfiler1 -i 192.168.150.104
• fas3170> vfiler status -a
Remove .105 (remove the alias then the ip from the vfiler)
• fas3170> ifconfig ns1 -alias 192.168.150.105
• fas3170> vfiler remove fas6080b_vfiler1 -i 192.168.150.105
• fas3170> vfiler status -a
Bring up the .104 interface so it is configured
• fas3170> ifconfig ns1 alias 192.168.150.104
fas3170> vfiler status -a # note that the interface is now configured
• Edit /etc/rc
• Optionally – use vfiler setup FAS3170> vfiler run vfilername setup -e
ns1:ip:subnet - **** NOTE: You can ifconfig a new interface or ifconfig alias an
existing interface from vfiler0, or run “vfiler run vfilername setup -e
interface:ip:subnet”. Setup will wack several setup files (hosts, hosts.equiv,
- resolv.conf, exports, nsswitch.conf) so be careful to restore from .bak if
- Setup -e will create an alias if the interface is already in use.
