By default, an ESXi host automatically performs a rescan every five minutes. A volume might appear between
the time you create it and assign it to a host, before you perform a manual rescan. Regardless, you can
perform a manual rescan to ensure all volumes are configured properly.
Step 1. Create one or more volumes and assign them to the ESXi host.
Step 2. If using a vCenter Server, add the host to the server's inventory.
Step 3. Use the vSphere Client or the vSphere Web Client to connect directly to the vCenter Server or to
the ESXi host.
Step 4. For instructions on how to perform a rescan of the storage on an ESXi host, search for the VMware
Knowledge Base article on this topic.
Configure storage on the host
You can use the storage assigned to an ESXi host as either a Virtual Machine File System (VMFS) datastore
or a raw device mapping (RDM).
Before you begin
The volumes mapped to the ESXi host must have been discovered properly.
All 5. x versions of ESXi support VMFS versions 5 and 3. You must use VMFS version 5 unless the datastore
also must be used by an ESX/ESXi 4.x host, which supports only VMFS version 3. All 6. x versions of ESXi
support VMFS versions 5 and 3, although a new VMFS-3 cannot be created.
For instructions on creating VMFS datastores using either the vSphere Client or the vSphere Web Client, see
the VMware pubs webpage (https://www.vmware.com/support/pubs/) for documentation on this topic.
For instructions on using volumes as RDMs using either the vSphere Client or the vSphere Web Client, see
the VMware pubs webpage (https://www.vmware.com/support/pubs/) for documentation on this topic.
Verify storage access on the host
Before you use a volume, you verify that the host can write data to the volume and read it back.
Step 1. Verify that the volume has been used as a Virtual Machine File System (VMFS) datastore or has
been mapped directly to a VM for use as a raw device mapping (RDM).
Linux express configuration
This chapter describes how to configure a Linux-based host using the express configuration method.
Decide whether to use this Express method
The express method for installing your storage array and accessing ThinkSystem System Manager is
appropriate for setting up a standalone Linux host to a DE Series storage system. It is designed to get the
storage system up and running as quickly as possible with minimal decision points.
1. Setting up one of the following communication environments:
• Fibre Channel (FC)
• iSCSI
• SAS
2. Creating logical volumes on the storage array and assigning a logical unit number (LUN) to each volume.
3. Making the volume LUNs available to the data host.
