Configure Storage System for NFS Redhat Linux (UNIX)

Configure Storage System for NFS Redhat Linux (UNIX)

1. Create the aggregate.

 2. Create the volume.

3. Record the IP address and host name for each entry in the /etc/hosts and check

    > ping xxx.xxx.xxx.xxx
    > ping Server Name

4. NFS will automatic export when volume created, to avoid

    > options nfs.export.auto-update off

5. Check whether NFS is license if not, add license using

    > license add xxxxxxx

5. Check the qtree security is in UNIX, if not

    > qtree security  ( volume path | qtree path ) UNIX

6. export the volume or qtree using exportfs command

   Syntax: exportfs -io rw,root="Host IP addrress"  volume path

   > exportfs -io rw,root=10.10.10.10   /vol/vol1    = This entry in memory not in /etc/exports

   > exportfs 

   > exportfs -p  rw,root=10.10.10.10  /vol/vol1     = This command make the entry in /etc/exports

   > rdfile /etc/exports

   > exportfs -v /vol/vol1                                         = This command will export particular volume in  
                                                                                         /etc/exports file.




7. To check the exported volume or qtree

   > exportfs -c 10.10.10.10 /vol/vol1                     = This command will check the access

   > exportfs                                                            = This command show list from nfs memory

8. Create on directory in server

   > mkdir /mount

   Syntax:  mount filler ip address: volume or qtree path /mount point

   > mount 10.10.10.11:/vol/vol1 /mount                = vol1 is mount in the /mount directory in the server  

   > cd /mount                                                          = Get in to mount directory  

   > mkdir test_folder                                             = make directory in the mounted directory

9. Permanent mounting in server side for consistency reboot

   > service nfs restart

   > chkconfig nfs on ( consistency reboot )

   > cat  /etc/fstab (depends on UNIX Server (OS))

   Syntax for FSTAB: (linux) and entry depends on UNIX Server (OS)

     <file system>                 <dir>        <type>    <options>    <dump>   <pass>

   > 10.10.10.10:/vol/vol1    /mount          -               -                -              -

   > Press Ctrl+c                                                     = To save and exit from cat command

10. Now NFS is working properly

Snapvault

SNAPVAULT

Ø Snapvault is license product in Ontap

Ø SnapVault is a disk-based storage backup feature of Data ONTAP

Ø Snapvault enable data stored on multiple storage be backup in centrally

Ø The qtree is the basic unit of SnapVault backup and restore

Ø Data is restored from the secondary qtree to primary qtree

Ø Using Nearstore_option license we can increase the concurrent transfer

Ø In snapvault primary and secondary may be flex-volume to traditional volume.

SNAPVAULT PREREQUISITES:-

Ø License for the snapvault primary is sv_ontap_pri.

Ø License for the snapvault secondary is sv_ontap_sec.

Ø TCP port 10566 and 10000 must be open.


Snapvault snap sched

Using snapvault snap we can take snapshot primary and secondary volume

In snapvault three types of snap schedule
sv_hourly
sv_daily
sv_weekly

Example:

Pri > snapvault snap sched vol1 sv_hourly 10@10-16

This schedule takes every hour snapshot on vol1 and retain last 10 snapshot copies name called sv_hourly in the primary system.

Sec > snapvault snap sched –x vol1 sv_hourly 10@10-16

This schedule takes every hour snapshot on vol1 and retain last 10 snapshot copies name called sv_hourly in the Secondary system.

Using –x for incremental back up, that means secondary snapvault that compare the primary snapshot and if any modified data in the primary snapshot, it will copied the modified date to the secondary system.

NOTE: If you don’t use the -x option, the secondary does not contact the primary. This schedule take snapshot of vol1 without incremental

NetApp NFS

NetApp Network File System

NFS is based on client-serve architecture.
NFS have three version are Version  2, 3 and 4.
NFS Stateful mean is "The information is stored (remember ) by the server between separate of a particular user on the client.
NFS Version2 and Version3 are state-Less protocol.
NFS Version4 is State-Full protocol.
Ontap NFS be a NIS Slave.
We can specify rw and ro permission for the same host within a single export and the result will be line entry error.
The target to receive exported resources in mountPoint.

NFS - NETWORK FILE SYSTEM

Network File System

• NFS allows network systems (clients) to access shared files and directories that are stored and administered centrally from a storage system

• Platforms that support NFS
  – Solaris™
  – Linux®
  – HP-UX®

Cifs

1. In a CIFS environment, the storage system authenticates users in one of four ways:

1. Active Directory authentication
2. Microsoft® Windows NT® 4.0 domain authentication 
3. Windows workgroup authentication
4. Authentication for non-Windows workgroups

2. we can manage the cifs in Three Methods:

1. command line 
2. filer view
3. computer management port 

3. Preparing for CIFS

To prepare a storage system to support Windows client users, complete the following steps:

1. License CIFS.

> License add <license>

> license (To check the license status)

2. Perform the initial CIFS configuration by running the cifs setup & cifs terminate program.

> cifs setup (command to on cifs  services)
> cifs terminate (command to off cifs services)

4. Volume share

> cifs shares -add share_name vol1

5. Qtree share

> cifs shares -add share_name /vol/vol_name/qtree_name.

go windows server now:

start -> run
Type //netapp ipaddress or //filer name

Then you can able to views the share folder.
