vSphere Storage Prerequisites Make sure to power off the virtual machine if you want to edit the existing WWNs. Before you begin, ensure that your SAN administrator has provisioned the storage LUN ACL to allow the virtual machine’s ESXi host to access it. Procedure 1 Open the Virtual Machine Properties dialog box by clicking the Edit Settings link for the selected virtual machine. 2 Click the Options tab and select Fibre Channel NPIV. The Virtual Machine Properties dialog box opens. 3 Edit the WWN assignments by selecting one of the following options: Option Description Temporarily disable NPIV for this virtual machine Disable the WWN assignments for the virtual machine. Leave unchanged The existing WWN assignments are retained. The read-only WWN Assignments section of this dialog box displays the node and port values of any existing WWN assignments. Generate new WWNs New WWNs are generated and assigned to the virtual machine, overwriting any existing WWNs (those of the HBA itself are unaffected). Remove WWN assignment The WWNs assigned to the virtual machine are removed and it uses the HBA WWNs to access the storage LUN. This option is not available if you are creating a new virtual machine. 4 Click OK to save your changes. 42 VMware, Inc.
Modifying Fibre Channel Storage for 5 ESXi This section discusses many of the storage devices supported in conjunction with VMware ESXi. For each device, it lists the major known potential issues, points to vendor-specific information (if available), and includes information from VMware knowledge base articles. NOTE Information related to specific storage devices is updated only with each release. New information might already be available. Consult the most recent Storage/SAN Compatibility, check with your storage array vendor, and explore the VMware knowledge base articles. This chapter includes the following topics: n “Testing ESXi SAN Configurations,” on page 43 n “General Setup Considerations for Fibre Channel SAN Arrays,” on page 44 n “EMC CLARiiON Storage Systems,” on page 44 n “EMC Symmetrix Storage Systems,” on page 45 n “IBM System Storage DS4800 Storage Systems,” on page 46 n “IBM Systems Storage 8000 and IBM ESS800,” on page 47 n “HP StorageWorks Storage Systems,” on page 47 n “Hitachi Data Systems Storage,” on page 48 n “Network Appliance Storage,” on page 48 n “LSI-Based Storage Systems,” on page 49 Testing ESXi SAN Configurations ESXi supports a variety of SAN storage systems in different configurations. Generally, VMware tests ESXi with supported storage systems for basic connectivity, HBA failover, and so on. Not all storage devices are certified for all features and capabilities of ESXi, and vendors might have specific positions of support with regard to ESXi. Basic connectivity Tests whether ESXi can recognize and operate with the storage array. This configuration does not allow for multipathing or any type of failover. HBA failover The server is equipped with multiple HBAs connecting to one or more SAN switches. The server is robust to HBA and switch failure only. Storage port failover The server is attached to multiple storage ports and is robust to storage port failures and switch failures. VMware, Inc. 43
