The Step by Step Guide
Leading off with the Snapsot Creation
Fist lets get logged into EMC Unisphere and get started
Snapshots
-Create snapshot
Storage Tab – select storage group
Locate the Lun – right click and select create snapshot
-Restore snapshot
Data Protection Tab
Locate Lun to restore – select snapshot – select restore
-mount points – allows you to restore the snapshot to another Host
Locate LUN – right click select snapshot mount point provide name and associated storage group
Data Protection – Locate Snapshot – select attach
select the host to attach mount point and select OK – Finish
LUN’s
Thin Provisioning vs Thick Provisioning
-Thick LUNs will allocate & reserve all the space up front and will never run out of initial allocated space (Thick LUNs has associated prerequisites to FAST VP and thick pools that allow for optimized storage tiering)
-Thin LUNS will present more storage to a HOST than is physically allocated (Thin LUNS show lower performance margins than thick LUNS) Over subscription is allowed so close monitoring and or alerting would be a best practice when choosing thin provisioned LUNs.
LUN creation
Step 1:
-Create LUN
Select Storage Pool
Storage – storage configuration – Storage pool
Select create – select pool type – create the name – select raid configuration & disk
LUN creation
Navigate to Storage – LUNS
Select create – select storage pool type – select Thin or Thick under LUN properties
Provide LUN name – apply – select cancel to close the window
*Note: You can create multiple LUN’s at the same time
Step 2:
-Add LUN to a Storage group
Select Storage – LUNS
Select LUN to add – select add to storage group
Select storage group and add to storage – select OK
Alternate method – Better Method (You can chose the HOST LUN ID)
-Add LUN to a Storage group
Select Host – Storage group
Select Storage group – Connect LUNs
Select LUN and set the LUN ID
* Note For LUNS for NAS – The Host LUN ID must be above 15
CIFS
Cifs & CIFS Server Creation
EMC VNX has two different OS FLAR (Fiber Logic Array Runtime Environment) which runs the EMC Clarion Storage System for block access & DART (Data Access in Real Time) which is a modified UNIX kernel with additional functionality added to operate as a file server for file access.
A Virtual Data Mover (VDM) is an EMC VNX software feature that enables the grouping of CIFS and/or NFS file system and servers in to virtual containers
Step 1:
Create a File System
Create LUNs and present them to the data mover
Control Station is used to manage the file storage
Step 1:
-Create a storage pool
Select Storage – Storage configuration – Storage Pool
Select storage pool type
Name the storage pool
Select performance type if you selected Auto -Teiring
*note if you only have 1 type of disk you would use raid 5 (4+1) with 10 or more disk
Select OK
Step 2:
-Create LUN
Select Storage – LUNs
Select create
Select raid pool type – Pool
Select storage Pool previously created in step 1
Select capacity
Select Thick LUN type under LUN properties
* EMC’s best practices state you should provision Thick LUN’s for file systems
Select apply – select close
Step 3:
-Allocate LUNS to File storage
Select Hosts – Storage groups
Select storage group – Connect LUNs
Select LUNs from SP section – select ADD
Select individual LUN from selected LUNs section and provide LUN ID
*NOTE select a LUN ID greater than 15 for file access
Select OK – select Yes – cancel
Step 4:
-Verify the storage pool is available
Select Storage – storage Configuration – Storage Pool for File
Rescan storage systems
Step 5:
-Create the File system
Select Storage – Storage configuration – File system
Create
Select create from storage pool
Name the file system
Select storage capacity size
Step 6:
-Create CIFs Server
Select storage – shared folders – CIFs
Select the CIFS servers tab – select Create
Select the data mover
Select Server type ex. Active Directory
Select computer name
Provide Domain credentials
Select interface
Select OK
Step 7:
-Create CIFS Share
Select Storage – Shared Folders – CIFS
Select the Shares Tab – select create
Select data mover
Provide CIFS share name
Select file system
Select path \\
*Note if you share out or export the root level 2 system files will be visible inside the share
Select CIFS server
Select OK
NFS
-Create a NFS Export
Step 1:
Select Storage – Shared Folder – NFS
Select create – select data mover
Select file system – select path
Add IP addresses individually or by subnet ranges into to correct ACL list
Select OK
Troubleshooting
Select Systems – Monitoring and Alerts – chose the appropriate task (alerts,eventlogs, background task and etc.)
