Info

vSphere Storage If the device does not support T10 SCSI or provides partial support, ESXi reverts to using the VAAI plug-ins, installed on your host, or uses a combination of the T10 SCSI commands and plug-ins. The VAAI plug-ins are vendor-specific and can be either VMware or partner developed. To manage the VAAI capable device, your host attaches the VAAI filter and vendor-specific VAAI plug-in to the device. For information about whether your storage requires VAAI plug-ins or supports hardware acceleration through T10 SCSI commands, see the vSphere Compatibility Guide or check with your storage vendor. You can use several esxcli commands to query storage devices for the hardware acceleration support information. For the devices that require the VAAI plug-ins, the claim rule commands are also available. For information about esxcli commands, see Getting Started with vSphere Command-Line Interfaces. Display Hardware Acceleration Plug-Ins and Filter To communicate with the devices that do not support the T10 SCSI standard, your host uses a combination of a single VAAI filter and a vendor-specific VAAI plug-in. Use the esxcli command to view the hardware acceleration filter and plug-ins currently loaded into your system. In the procedure, --server=server_name specifies the target server. The specified target server prompts you for a user name and password. Other connection options, such as a configuration file or session file, are supported. For a list of connection options, see Getting Started with vSphere Command-Line Interfaces. Prerequisites Install vCLI or deploy the vSphere Management Assistant (vMA) virtual machine. See Getting Started with vSphere Command-Line Interfaces. For troubleshooting , run esxcli commands in the ESXi Shell. Procedure u Run the esxcli --server=server_name storage core plugin list --plugin-class=value command. For value, enter one of the following options: n Type VAAI to display plug-ins. The output of this command is similar to the following example: #esxcli --server=server_name storage core plugin list --plugin-class=VAAI Plugin name Plugin class VMW_VAAIP_EQL VAAI VMW_VAAIP_NETAPP VAAI VMW_VAAIP_CX VAAI n Type Filter to display the Filter. The output of this command is similar to the following example: esxcli --server=server_name storage core plugin list --plugin-class=Filter Plugin name Plugin class VAAI_FILTER Filter Verify Hardware Acceleration Support Status Use the esxcli command to verify the hardware acceleration support status of a particular storage device. In the procedure, --server=server_name specifies the target server. The specified target server prompts you for a user name and password. Other connection options, such as a configuration file or session file, are supported. For a list of connection options, see Getting Started with vSphere Command-Line Interfaces. Prerequisites Install vCLI or deploy the vSphere Management Assistant (vMA) virtual machine. See Getting Started with vSphere Command-Line Interfaces. For troubleshooting , run esxcli commands in the ESXi Shell. 218 VMware, Inc.
Procedure u Run the esxcli --server=server_name storage core device list -d=device_ID command. The output shows the hardware acceleration, or VAAI, status that can be unknown, supported, or unsupported. # esxcli --server=server_name storage core device list -d naa.XXXXXXXXXXXX4c naa.XXXXXXXXXXXX4c Display Name: XXXX Fibre Channel Disk(naa.XXXXXXXXXXXX4c) Size: 20480 Device Type: Direct-Access Multipath Plugin: NMP XXXXXXXXXXXXXXXX Attached Filters: VAAI_FILTER VAAI Status: supported XXXXXXXXXXXXXXXX Verify Hardware Acceleration Support Details Use the esxcli command to query the block storage device about the hardware acceleration support the device provides. In the procedure, --server=server_name specifies the target server. The specified target server prompts you for a user name and password. Other connection options, such as a configuration file or session file, are supported. For a list of connection options, see Getting Started with vSphere Command-Line Interfaces. Prerequisites Install vCLI or deploy the vSphere Management Assistant (vMA) virtual machine. See Getting Started with vSphere Command-Line Interfaces. For troubleshooting , run esxcli commands in the ESXi Shell. Procedure u Run the esxcli --server=server_name storage core device vaai status get -d=device_ID command. If the device is managed by a VAAI plug-in, the output shows the name of the plug-in attached to the device. The output also shows the support status for each T10 SCSI based primitive, if available. Output appears in the following example: # esxcli --server=server_name storage core device vaai status get -d naa.XXXXXXXXXXXX4c naa.XXXXXXXXXXXX4c VAAI Plugin Name: VMW_VAAIP_SYMM ATS Status: supported Clone Status: supported Zero Status: supported Delete Status: unsupported Chapter 21 Storage Hardware Acceleration VMware, Inc. 219
