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 192.168.0.10
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=192.168.0.25,root=192.168.0.25,nosuid /vol/myvolume_bkup
Step 4) /etc/fstab entry on Server –
192.168.0.10:/vol/myvolume_bkup /backup nfs defaults,hard,rw,rsize=65536,wsize=65536,proto=tcp 0 0
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
* Serial ports – The serial ports include console port, which connects the storage system to a serial
terminal that you can use as a console.
