Netapp Interview Questions and Answers For Freshers

1. What is NetApp storage?

Across physical and hybrid cloud environments, businesses and specialised cooperatives rely on NetApp's storage hardware device to store and exchange vast amounts of complex data. The object data is blocked, recorded, and stored securely thanks to the hybrid and all-glimmer storage frameworks built into the NetApp warehousing hardware.

2. As a developer, how will you improve the performance of storage in Netapp?

This may seem like something other than encouraging, but an established method for doing so currently needs to be established. However, there are many options for improving storage efficiency. These methods include-

  • A specific volume/lun is now stored on ATA/SATA hard drives but might be relocated to FC/SAS instead. The performance enhancement potential of the streak store should be considered.
  • Instead of focusing on a single interface, multi-mode vif can be set up to optimise data transfer and react to internal failure in the NFS/CIFS instance.
  • Maintaining an aggr/vol ratio of 90% or below is strongly advised.
  • Avoid alternating between different volume reinforcements in the same period.
  • For more efficient striping, it is recommended that data be redistributed using aggr/volume/lun reallocation.
  • After normal business hours, set up a cleaning and de-duplication filtering schedule.
  • Construct several concentric circles and connect them using a variety of rack types. 
  • Stay Avoid agitating the disc at numerous paces and the ring at multiple types. 
  • Keep a good supply of spare plates on hand in case of circle disappointment since remake time will add extra time and lead to erroneous performance. 
  • Maintain the well-informed firmware/programming variant recommended by Netapp.


3. What do you understand about virtualization in NetApp?

Virtualisation in the context of NetApp is the reliable simulation of hardware components. It's a method for tracking and distributing hardware and resources regardless of their form or location. Through virtualization, several physical storage devices in a system are combined into what looks like a single storage device and manages from a centralised location. Storage virtualization is typically implemented in a storage area network. Capacity device management might be a snoozefest. By disguising the true unpredictability of the SAN, capacity virtualisation allows the capacity manager to complete the tasks of reinforcement, filing, and recovery more efficiently and in less time.

4. What do you understand by HA in NetApp?

In the context of NetApp, HA means "High Availability." HA is a novel approach to achieving failover with reduced downtime. Customers nowadays expect servers to be available around the clock, every day of the year (hence the term "24x7x365"), so server farms must implement redundant systems to ensure their services are always available. This includes having a backup database and application servers ready to take over if one of the primary servers experiences an outage. When a HA arrange structure is in place, a power outage never affects the end user.

5. How to fix the issue of not being able to map Lun to Solaris server, when there is no issue on the Solaris server?

The following safeguards can be implemented to deal with this problem:

  • Ensure the capacity you need is covered by your iscsi/fcp permit. 
  • Verify the iscsi/fcp meeting is registered on the server side for the order 
  • When using Netapp> igroup, v
  • Lun checks are scheduled to be sent to the igroup being compared.
  • Verify that the correct host type is used when creating igroups and luns.
  • Inspect the igroup to see if the correct iqn/wwpn element was added.
  • If using an FCP-style zoning convention, ensure the switch side is set up correctly.


6. How can you build the LUN for running a command on the Linux server?

That's a quick and easy task. Enter lun create -s size -t Linux /vol/vol1/lunname into a command prompt.

7. List out the commands for qtree & security facilitation?

The necessary instructions are as follows:

  • Netapp>qtree create /vol/vol1/qtreename
  • Netapp>qtree security /vol/vol1/qtree unix|ntfs|mixed


8. What is the procedure that you can use if you want to copy a volume filer to a standard filer?

Executing the ndmpcopy or snapmirror command is all required to complete the operation.

9. What is the procedure to resize the aggregate of a given range?

Just run the following Command- Netapp> aggr add AggName no.of.disk

10. How can you increase the given volume of the Netapp environment?

The following command, vol add VolName no.of.disk, can expand the default Traditional Volume.

Execute vol size VolName +60g to add 60g to the Flexible Volume.

11. What do you understand by QTree?

There are many ways in which a qtree differs from the standard UNIX framework catalogue:

  • Qtrees can be distributed securely. A qtree can be created using UNIX, NT, or a hybrid security model.
  • The qtree supports enabling CIFS oplocks. Customers are aided in buffering data locally via CIFS oplocks, encouraging reading ahead from an already open document. The concept of oplocks allowed is crucial to the idea of buffering.
  • Circle space and record restrictions can be established at the qtree level, giving us command over-allocating resources to different projects. 


Let's pretend there are three departments—fund, human resources, and deals—all using their qtrees. Then we may give 20 GB to sales, 100 GB to human resources (including recording staff and archiving old ones), and 75 GB to finance.

12. What is the limit of the snap reserve that is available by default for aggregate in NetApp?

In NetApp, 5% is used as the default amount for the aggregate snaps reserve.

13. What do you understand by snapshot?

Snapshot duplication, available in the NetApp environment, is a read-only snapshot of a custom or FlexVol volume or total that freezes the state of the document framework at a specific instant in time.

14. What different kinds of protocol are there for usage in NetApp?

NFS, CIFS, iSCSI, and FCP are the only protocols that can be used.

14. Illustrate the differences between Iscsi And Fcp?

Throughput is impeded by iSCSI transmission. iSCSI can coexist with preexisting infrastructures and doesn't require a dedicated one. The TCP/IP protocol is used, and it functions properly.

Fibre optic fcp transmission. It calls for a committed FC setup. In contrast to the iSCSI, the execution is extreme.

15. Illustrate the differences between Ndmp Copy And Vol Copy?

  • Ndmp copy: The protocol for managing data networks (also known as tape reinforcement).
  • Vol duplicate: This procedure is used to copy the volume to the same or a different total.


16. What is the port number for iSCSI?

The default ISCSI port is 3260.

17. What do you understand by SAN?

The abbreviation "SAN" refers to a network for storing data. The term "storage area network" (SAN) is used to describe a specific type of fast-reasoning arrangement (or subnetwork) that links together multiple information storage devices and related information servers for a larger client system. Registering a company's assets typically includes a capacity territory organise. Storage area networks are frequently near other registering assets like IBM Power5 systems. Still, they can extend to remote locations for reinforcement and recorded storage using wide area network bearer improvements like ATM or SONET.

Some SAN framework integrators liken it to the typical stockpiling transport (a data stream) in a PC shared by different types of capacity gadgets, such as a hard circle or a CD-ROM player. This allows NetApp engineers to use correspondence innovations like IBM's optical fibre ESCON or the more recent Fibre Channel technology.

18. What do you understand by NAS?

Network-attached storage is often abbreviated as NAS. Storage space on a hard disc array that is not directly connected to the server PC in an office but has its unique IP address is known as network-attached storage (NAS). When storage access and management are removed from the division server, applications and documents can be provided more quickly since they no longer compete for the same processing resources. The system-attached storage device is wired into the local area network (often an Ethernet setup) and given its unique Internet Protocol address. The primary server coordinates with the NAS document server to fulfil document requests.

Hard disc storage, such as RAID arrays with many drives per array, and record-management software are all part of a system's tethered capacities. A capacity territory organises (SAN) is an increasingly sophisticated capacity framework, and the system-added position might be a step towards and part of it.

Microsoft's Internetwork Packet Exchange and NetBEUI, Novell's Netware Internet Packet Exchange, and Sun Microsystems' Network File System are just a few of the many system conventions that can usually be handled by NAS programming. In most cases, a Web-based application can make the necessary arrangements, including configuring client access requirements.

NetApp Interview Questions For Experienced

19. What is LIF?

For "Logical interface," the abbreviation "LIF" is commonly used. As the name suggests, a consistent interface is built from the physical interface of NetApp controllers.

20. Explain how the de-duplication process works.

De-duplication, in the context of disc storage, refers to any calculation that looks for and gets rid of redundant copies of data objects (such as squares, lumps, or documents). Information that is a copy is not stored when it is discovered; instead, an "information pointer" is updated such that the storage framework points to a precise replica of the information item previously stored on the ring. This De-duplication component works wonderfully with copious amounts of duplicated data (like entire reinforcements).

21. What Command would you use to view the total space that you have saved by the process of De-duplication?

The following Command must be entered:

df -s

22. What command would you use to see how far along the de-duplication process is?

The sis status command must be executed.

23. Explain how to create a Snapvault snapshot schedule in detail.

pri> snapvault snap sched vol1 sv_hourly 22@0-22
  • This strategy is intended for use with the Home Registries Volume 1
  • Except for 11:00 p.m., it makes a copy of the most recent Snapshot every hour. 
  • Hourly duplicates are stored for nearly a full day.

24. To what extent are you familiar with the concept of Metadata?

Metadata is data about data, or at least the information about information.

  • Inode document
  • Used square bitmap document
  • Free square bitmap document.

25. List out the steps required to configure SnapMirror successfully.

The four steps of the SnapMirror design process are as follows:

Step 1: Allow SnapMirror on both the source and target frameworks.

authorise covering

Step 2: Locate their hostnames or IP addresses on the source to approve SnapMirror frameworks for recreating this source framework.

alternatives snapmirror.access host=dst_hostname1,dst_hostname2

Step 3: Execute an underlying gauge move to cause a recreation of each source volume or qtree. Using SnapMirror in bulk

Confining the target volume (vol confine dst_vol) comes first.

Then, using the following punctuation after the gauge's name, you should introduce the volume SnapMirror:

snapmirror introduce - S src_hostname:src_v

Step 4: Use the following language framework as a guide while performing a qtree SnapMirror benchmark operation:

snapmirror instate – S src_hostname:/vol/src_vol/src_qtree

26. How to troubleshoot the baseline transfer error?

The following are some possible approaches:

  • Use the command "ping" to ensure that packets can reach hosts of both types.
  • Check the firewall to see if TCP ports 10566 and 10565 are open.
  • Check to see if both filers have submitted the snapmirror permit.

27. What are the different replication modes?

SnapMirror's asynchronous mode replicates snapshots from a source volume or qtree to a target. It can support distances greater than 800 km. Size or q-tree. Calendar-based or manual execution of the snapmirror update order ensures consistency in update frequency. Both the amount SnapMirror and the qtree SnapMirror support the async mode.

The content of one volume is replicated onto another while staying in sync with the original using SnapMirror Sync mode. SnapMirror Sync is employed when there is zero tolerance for data loss. The entire more than 300-kilometer length won't be bolstered. 
SnapMirror Semi-Sync provides a compromise approach, keeping the source and target frameworks in sync more reliably than in Async mode but with less impact on performance.

28. How to troubleshoot the CIFS share response in a slow situation?

Here are some ways to accomplish that:

  • Use "cifs detail" and "sysstat - x 1" to double-check the r/w.
  • The problem lies on the filer's side if disc and CPU consumption is high.
  • If more plate r/w time is taken, such as during tape reinforcement and similarly during clean exercises, CPU consumption will be significant.


29. What exactly do you mean when you say "Junction Path?"

Volume intersections merge many volumes into a unified namespace to improve data accessibility for NAS users. Bunch mode is another name for this type of configuration.
