MultiStore

1. MultiStore is a software product you can use optionally.
2. MultiStore enables you to partition the storage and network resources of a single storage system so that it appears as multiple storage systems on the network.
3. Each "storage system" created as a result of the partitioning is called a vFiler unit.
4. A vFiler unit, using the resources assigned, delivers file services to its clients as a storage system does.The storage resource assigned to a vFiler unit can be one or more qtrees or volumes. The network resource assigned can be one or more base IP addresses or IP aliases associated with network interfaces.
5. You can add or remove resources at any time.
6. we don't need additional license for the vfiler unit, we can use physical filer license to vfiler unit.

Reasons for using MultiStore

MultiStore has many features that you can use for your provisioning needs.

1. To consolidate multiple servers to one storage system.
2. To use the storage system to host data for multiple customers, such as clients of a service provider or different organizations within an enterprise.
3. To use the SnapMirror technology for migrating data from one storage system to another
   transparently.

Some limitations of MultiStore

1. You can have a maximum of 65 vFiler units on a storage system. You can create 64 vFiler units on a storage system. The 65th vFiler unit is vfiler0, which is created automatically when MultiStore is licensed on the storage system.
2. In an active/active configuration, you can create up to 64 vFiler units on each node of the active/active configuration, for a maximum of 130 vFilers in the active/active configuration.
3. Only Ethernet interfaces are supported for vFiler units
4. Only the NFS, CIFS, iSCSI, HTTP, and FTP protocols are supported for the vFiler units. However, protocols not supported on vFiler units are supported on vfiler0, the default vFiler unit.

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
