vSphere Storage 9 On the Properties page, type a datastore name and click Next. 10 If the space specified for storage is excessive for your purposes, you can adjust the capacity values. By default, the entire free space on the storage device is available. 11 Click Next. 12 In the Ready to Complete page, review the datastore configuration information and click Finish. A datastore on the SCSI-based storage device is created. If you use the vCenter Server system to manage your hosts, the newly created datastore is added to all hosts. Create a VMFS Datastore in the vSphere Web Client VMFS datastores serve as repositories for virtual machines. You can set up VMFS datastores on any SCSI-based storage devices that the host discovers, including Fibre Channel, iSCSI, and local storage devices. Prerequisites n Install and configure any adapters that your storage requires. Rescan the adapters to discover newly added storage devices. n Browse to Datastores in the vSphere Web Client navigator. See “Display Datastore Information in the vSphere Web Client,” on page 23. Procedure 1 Click the Create a New Datastore icon. 2 Type the datastore name and if required, select the placement location for the datastore. The vSphere Web Client enforces a 42 character limit for the datastore name. 3 Select VMFS as the datastore type. 4 Select the device to use for your datastore. IMPORTANT The device you select must not have any values displayed in the Snapshot Volume column. If a value is present, the device contains a copy of an existing VMFS datastore. For information on managing datastore copies, see “Managing Duplicate VMFS Datastores,” on page 162. 5 Select the VMFS version. Option Description VMFS 5 Enables more than 2TB LUN support. VMFS 3 Allows ESX/ESXi hosts version lower than 5.0 to access the datastore. 6 Specify partition configuration. Option Description Use all available partitions Dedicates the entire disk to a single VMFS datastore. If you select this option, all file systems and data currently stored on this device are destroyed. Use free space Deploys a VMFS datastore in the remaining free space of the disk. 7 (Optional) If the space allocated for the datastore is excessive for your purposes, adjust the capacity values in the Datastore Size field. By default, the entire free space on the storage device is allocated. 8 For the VMFS3 version, select the maximum file size. 9 In the Ready to Complete page, review the datastore configuration information and click Finish. 160 VMware, Inc.
The datastore on the SCSI-based storage device is created. It is available to all hosts that have access to the device. Create NFS Datastore in the vSphere Client You can use the Add Storage wizard to mount an NFS volume and use it as if it were a VMFS datastore. Prerequisites Because NFS requires network connectivity to access data stored on remote servers, before configuring NFS, you must first configure VMkernel networking. Procedure 1 Log in to the vSphere Client and select the host from the Inventory panel. 2 Click the Configuration tab and click Storage in the Hardware panel. 3 Click Datastores and click Add Storage. 4 Select Network File System as the storage type and click Next. 5 Enter the server name, the mount point folder name, and the datastore name. For the server name, you can enter an IP address, a DNS name, or an NFS UUID. NOTE When you mount the same NFS volume on different hosts, make sure that the server and folder names are identical across the hosts. If the names do not match exactly, the hosts see the same NFS volume as two different datastores. This might result in a failure of such features as vMotion. An example of such discrepancy could be if you enter filer as the server name on one host and filer.domain.com on the other. 6 (Optional) Select Mount NFS read only if the volume is exported as read only by the NFS server. 7 Click Next. 8 In the Network File System Summary page, review the configuration options and click Finish. Create NFS Datastore in the vSphere Web Client You can use the New Datastore wizard to mount an NFS volume. Prerequisites n Configure VMkernel networking. NFS requires network connectivity to access data stored on remote servers. See the vSphere Networking documentation. n Browse to Datastores in the vSphere Web Client navigator. See “Display Datastore Information in the vSphere Web Client,” on page 23. Procedure 1 Click the Create a New Datastore icon. 2 Type the datastore name and if required, select the placement location for the datastore. The vSphere Web Client enforces a 42 character limit for the datastore name. 3 Select NFS as the datastore type. Chapter 17 Working with Datastores VMware, Inc. 161
