How to create volume in NetApp and how to NFS export

How to create volume in NetApp and how to NFS export


NetApp Storage supports multiple protocols to access data like NFS, CIFS(SMB), FTP and WebDav etc. This article explains how to create NetApp Volume and export using NFS.

Step 1) Check Aggr Space and Ping Storage connectivity from server (where u will be mounting volume) –

# ping -c5 -M do -s 8972

netapp-filer1> df -hA
Aggregate                total       used      avail capacity
aggr2                     16TB       14TB     2320GB      86%
aggr3                     16TB       14TB     1681GB      90%
aggr0                   1490GB     1251GB      239GB      84%
aggr1                     16TB       15TB     1511GB      91%
aggr4                     12TB     5835GB     7044GB      45%

Step 2) Create Volume –

netapp-filer1> vol create myvolume_bkup  -l en_US -s volume  aggr1 500g
Creation of volume ‘myvolume_bkup’ with size 1t on containing aggregate
‘aggr1’ has completed.

Step 3) Disable or Change snapshot and Reserve –

netapp-filer1> vol options myvolume_bkup
nosnap=off, nosnapdir=off, minra=off, no_atime_update=off, nvfail=off,
ignore_inconsistent=off, snapmirrored=off, create_ucode=off,
convert_ucode=off, maxdirsize=73400, schedsnapname=ordinal,
fs_size_fixed=off, compression=off, guarantee=volume, svo_enable=off,
svo_checksum=off, svo_allow_rman=off, svo_reject_errors=off,
no_i2p=off, fractional_reserve=100, extent=off, try_first=volume_grow,
read_realloc=off, snapshot_clone_dependency=off, nbu_archival_snap=off

netapp-filer1> vol options myvolume_bkup  nosnap on
netapp-filer1> snap reserve myvolume_bkup  0

netapp-filer1> df -h  myvolume_bkup
Filesystem               total       used      avail capacity  Mounted on
/vol/myvolume_bkup/      500GB      176KB      499GB       0%  /vol/myvolume_bkup/
/vol/myvolume_bkup/.snapshot        0TB        0TB        0TB     —%  /vol/myvolume_bkup/.snapshot

Step 4) Exports NFS –

netapp-filer1> exportfs -p sec=sys,rw=,root=,nosuid  /vol/myvolume_bkup

Step 4) /etc/fstab entry on Server –     /backup nfs     defaults,hard,rw,rsize=65536,wsize=65536,proto=tcp 0 0

Introduction to NetApp storage

Introduction to NetApp storage


The NetApp Storage system is a hardware and software-based data storage and retrieval
system. It responds to network requests from clients and fulfills them by writing data to or
retrieving data from its disk array. It provides a modular hardware architecture running the
Data ONTAP operating system and WAFL (Write Anywhere File Layout) software.
Data ONTAP is the operating system for all NetApp storage systems. It provides a complete set
of storage management tools through its command-line interface, through the FilerView
interface, through the DataFabric Manager interface (which requires a license), and for
storage systems with a Remote LAN Module (RLM) or a Baseboard Management Controller (BMC)
installed through the RLM or the BMC Ethernet connection to the system console.

The NetApp storage system consists of the following components –
1) The storage system main unit, or chassis, is also known as the storage engine. It
is the hardware device that receives and sends data + gathering h/w and other
information or configuration.
2) The disk shelves are the containers, or device carriers, that hold disks and
associated hardware (such as power supplies, connectivity, and cabling) that are
connected to the main unit of the storage systems.

Internal components –

* System board – The system board is also referred to as the main board of the storage system.
It has upgradable firmware. All components are connected to the system board.
* System memory – System memory stores information temporarily.
* NVRAM (Nonvolatile RAM) – Data ONTAP uses NVRAM to log network transactions as a data
integrity measure. In case of a system or power failure, Data ONTAP uses the contents of NVRAM to
restore network data to disk. and shutdown storage system if temp is high
* Slots and ports – The storage system has slots for external connections and ports for a
console and diagnostic hardware.
* Slots – The storage system contains expansion slots for host adapters like – NIC, Disk shelf and Tape
drive adaptar
* Serial ports – The serial ports include console port, which connects the storage system to a serial
terminal that you can use as a console.
