How to add a storage to ESX

Adding Local SCSI Storage
As soon as you load SCSI storage adapter drivers, ESX Server detects available SCSI storage devices. Before creating a new datastore on a SCSI device, you might need to perform a rescan.
When you create a datastore on a SCSI storage device, the Add Storage wizard guides you through the configuration steps.
To create a datastore on a local SCSI disk

• Log into the VMware VI Client and select the server from the inventory panel.
• Click the Configuration tab, and click Storage (SCSI, SAN, and NFS) under hardware.
• Click the Add Storage link.
• Select the Disk/LUN storage type, and click Next.

•  Select the SCSI device you want to use for your datastore, and click Next.
•  Look over the current disk layout, and click Next. 
•  Enter a datastore name. (The label name must be unique within the current Virtual Infrastructure instance) 
•  Click Next.

• If needed, adjust the file system and capacity values.

           By default, the entire free space available on the storage device is offered to you.

• Click Next.
• Review the datastore configuration information, and click Finish.

This process creates a datastore on the local SCSI disk on your ESX Server host.

Adding Fibre Channel Storage
Before creating a new datastore on a Fibre Channel device, rescan a Fibre Channel adapter to discover any newly added LUNs. 

When you create a datastore on a Fibre Channel storage device, the Add Storage wizard guides you through the configuration.
To create a datastore on a Fibre Channel device

• Log into the VMware VI Client, and select a server from the inventory panel.
• Click the Configuration tab, and click Storage (SCSI, SAN, and NFS) under hardware.
• Click the Add Storage link..
• Select the Disk/LUN storage type, and click Next.

• Select the Fibre Channel device you want to use for your datastore, and click Next.
• Look over the current disk layout, and click Next. 
• Enter a datastore name.
• The datastore name appears in the VI Client and must be unique within the current Virtual Infrastructure instance. 
• Click Next.

• If needed, adjust the file system values and capacity you use for the datastore.
  By default, the entire free space available on the storage device is offered to you.
• Click Next.
• Review the datastore information, and click Finish.
  This process creates the datastore on a Fibre Channel disk for the ESX Server host. 
• Perform a rescan

Creating an NFS-Based Datastore

When you create a datastore on an NFS volume, the Add Storage wizard guides you through the configuration steps.

To mount an NFS volume

• Log into the VMware VI Client, and select a server from the inventory panel.
• Click the Configuration tab, and click Storage (SCSI, SAN, and NFS) under hardware.
• Click the Add Storage link.
• Select Network File System as the storage type, and click Next.

• Enter the server name, the mount point folder, and the datastore name.
• Click Next.
• Review the configuration options and click Finish.
