2 In the Paths panel, right-click the path to disable, and select Disable.<br />
3 Click OK to save your settings and exit the dialog box.<br />
You can also disable a path from the adapter’s Paths view by right-clicking the path in the list and selecting<br />
Disable.<br />
Disable Paths in the <strong>vSphere</strong> Web Client<br />
You can temporarily disable paths for maintenance or other reasons.<br />
You disable a path using the Paths panel. You have several ways to access the Paths panel, from a datastore,<br />
a storage device, or an adapter view. This task explains how to disable a path using a storage device view.<br />
Procedure<br />
1 Browse to the host in the <strong>vSphere</strong> Web Client navigator.<br />
2 Click the Manage tab, and click <strong>Storage</strong>.<br />
3 Click <strong>Storage</strong> Devices.<br />
4 Select the storage device whose paths you want to disable and click the Paths tab.<br />
5 Select the path to disable and click Disable.<br />
Managing <strong>Storage</strong> Paths and Multipathing Plug-Ins<br />
Use the esxcli commands to manage the PSA multipathing plug-ins and storage paths assigned to them.<br />
You can display all multipathing plug-ins available on your host. You can list any third-party MPPs, as well<br />
as your host's NMP and SATPs and review the paths they claim. You can also define new paths and specify<br />
which multipathing plug-in should claim the paths.<br />
For more information about commands available to manage PSA, see the Getting Started with <strong>vSphere</strong> Command-<br />
Line Interfaces.<br />
Multipathing Considerations<br />
Specific considerations apply when you manage storage multipathing plug-ins and claim rules.<br />
The following considerations help you with multipathing:<br />
Chapter 20 Understanding Multipathing and Failover<br />
n If no SATP is assigned to the device by the claim rules, the default SATP for iSCSI or FC devices is<br />
VMW_SATP_DEFAULT_AA. The default PSP is VMW_PSP_FIXED.<br />
n When the system searches the SATP rules to locate a SATP for a given device, it searches the driver rules<br />
first. If there is no match, the vendor/model rules are searched, and finally the transport rules are searched.<br />
If no match occurs, NMP selects a default SATP for the device.<br />
n If VMW_SATP_ALUA is assigned to a specific storage device, but the device is not ALUA-aware, no claim<br />
rule match occurs for this device. The device is claimed by the default SATP based on the device's transport<br />
type.<br />
n The default PSP for all devices claimed by VMW_SATP_ALUA is VMW_PSP_MRU. The VMW_PSP_MRU<br />
selects an active/optimized path as reported by the VMW_SATP_ALUA, or an active/unoptimized path<br />
if there is no active/optimized path. This path is used until a better path is available (MRU). For example,<br />
if the VMW_PSP_MRU is currently using an active/unoptimized path and an active/optimized path<br />
becomes available, the VMW_PSP_MRU will switch the current path to the active/optimized one.<br />
