Inside a Virtual Machine Is Not Supported
UPDATED: Windows Server

Virtual machine
enters a paused state or a CSV volume goes offline when you try to create a
backup of the virtual machine on a Windows Server 2012-based failover cluster
“… recommend to
disable this functionality when storage behind CSV does not support ODX …”
Deploy Windows
Offloaded Data Transfers
“… (even better) recommend
making the upgrade to Hyper-V 2012 R2 … because it has a lot of polish specifically
around backup logic …”

## NetApp Brief Notes ##
SnapMirror: There must be at least one common snapshot for SnapMirror resync
to be possible, otherwise SnapMirror initialize must be done again.
The CMode equivalent of the 7Mode -
lun show -m
- command is -
lun mapped
This command helps register the node as being online on

autosupport invoke -node name

## NetApp Tips 1 ##
Tip for Creating Lots
of CIFS Shares in CDOT using Excel
Note: Remember to
place spaces as required!
Row 1 is for column titles.
Column A = vserver
cifs share create -vserver
Column B = {Populate with vserver names}
Column C = -share-name
Column D = “
Column E = {Populate with share names}
Column F = “
Column G = -path
Column H = “
Column I = {Populate with base path like ‘/NAME/’ }
Column J = {Populate with next level path like ‘SHARE’ }
Column K = {Populate with subsequent levels like ‘/folder’ }
Column L = “
Column M = -share-properties
Column N = {Populate with share properties such as ‘oplocks,browsable,changenotify’}
Column O = CONCATENATE(A2,B2,C2,D2,E2,F2,G2,H2,I2,J2,K2,L2,M2,N2)
And fill down for
as many shares as need to be created!
And some other commands to check you’re looking in the
right area:
1) To get IP address of fileserver from Windows:
C:\Users\Winuser>
ping FILESERVERNAME
2) To find which LIF owns that address (X.X.X.X is
obtained above):
CDOT::> net int show
-address X.X.X.X
3) To verify existing paths:
CDOT::> cifs share show
-vserver VSERVERNAME -fields path *PATH_STRING*
## NetApp Tips 2 ##
CDOT: Creating CIFS
Volume Quotas - Tracking Only Quotas
quota policy create -vserver vs1 -policy-name volumePolicy
vserver modify -vserver vs1 -quota-policy volumePolicy
quota policy rule create
-vserver vs1 -policy-name volumePolicy -volume testshare -type user -target "" -qtree ""
-soft-disk-limit 1g
quota modify -vserver vs1 -volume testshare -state on
quota report -vserver vs1 -volume testshare

## NetApp - Troubleshooting 2: fru_led
##
OEM: Fault LEDs
constantly lit on 62xx, 32xx, and 22xx systems
For Data ONTAP
versions 8.1.3 or later:
From the SP CLI:
SP node> priv set diag
SP node*> system fru led show 0
From the Data ONTAP
7-mode shell or clustered Data ONTAP nodeshell:
node> priv set diag
node*> fru_led status
node*> show_faults
To turn off all
LEDs:
node*> fru_led off all
That is really nice and easy! My son would enjoy this!
