6.5 SETTING THE DEFAULT PSP FOR ALUA TO ROUND ROBIN To set the default PSP for ALUA to round robin, follow these steps: 1. Connect to the CLI of an ESX or ESXi server. 2. From the console, run: esxcli nmp satp setdefaultpsp -–psp <PSP type> -–satp <SATP type> Available PSP types in vSphere are: VMW_PSP_RR VMW_PSP_FIXED VMW_PSP_MRU Available SATP types for NetApp arrays are: VMW_SATP_DEFAULT_AA VMW_SATP_ALUA Example of executing this command: esxcli nmp satp setdefaultpsp --psp VMW_PSP_RR --satp VMW_SATP_ALUA 3.To verify the results of this command, typeesxcli nmp satp list: 4. Repeat steps 1 through 3 for each ESX or ESXi server. 6.6 MANUALLY SETTING THE PSP FOR A DATASTORE 1. Open vCenter Server. 2. Select an ESX server. 3. In the right pane, select the Configuration tab. 4. In the Hardware box, select Storage. 5. In the Storage box, highlight the storage and select the Properties link. 6. In the Properties dialog box, click the Manage Paths button. 7. Set the multipathing policy to round robin. 6.7 MANUALLY SETTING THE PSP FOR A LUN An alternative method for setting the preferred path for multiple LUNs is available in vCenter Server. To set the path, follow these steps: 1. Open vCenter Server. 2. Select an ESX server. 3. In the right pane, select the Configuration tab. 4. In the Hardware box, select Storage Adapters. 5. In the Storage Adapters pane, select a host bus adapter. 6. Highlight all of the LUNs to configure.
15 CLI Configuration Processes for NetApp and VMware vSphere Storage Arrays Running Data ONTAP and ESX/ESXi Server7. Right-click the highlighted LUNs and select Manage Paths. 8. In the Manage Paths window, set the multipathing policy and preferred path for all of the highlighted LUNs. 7 MANUAL STORAGE CONFIGURATIONS FOR NFS 7.1 INCREASING THE NUMBER OF NFS DATASTORES By default, VMware ESX is configured to support up to eight Network File System (NFS) datastores; however, this limit can be increased to 64 in order to meet the needs as the virtual infrastructure grows. While the maximum number of NFS datastores (64) is less than what is available with VMFS datastores (256), this difference is offset by the density available to NetApp NFS datastores. To make sure of availability, NetApp recommends that you increase the maximum number of datastores available when deploying an ESX server. Preconfiguring this setting makes sure that NFS datastores can be added dynamically at any time without disruption or effort. To make this change, follow these steps from within the virtual infrastructure client: 1. Open vCenter Server. 2. Select an ESX host. 3. In the right pane, select the Configuration tab. 4. In the Software box, select Advanced Configuration. 5. In the pop-up window, left pane, select NFS. 6. Change the value of NFS.MaxVolumes to 64. 7. In the pop-up window, left pane, select Net.
