6.7

Generally, the NMP determines which SATP to use for a specific storage device and associates the SATP
with the physical paths for that storage device. The SATP implements the tasks that include the following:
n
Monitors the health of each physical path.
n
Reports changes in the state of each physical path.
n
Performs array-specific actions necessary for storage fail-over. For example, for active-passive
devices, it can activate passive paths.
ESXi includes several generic SATP modules for storage arrays.
VMW_SATP_LOCAL SATP for local direct-attached devices.
As of vSphere 6.5 Update 2 release, VMW_SATP_LOCAL provides
multipathing support for the local devices, except the devices in 4K native
format. To claim multiple paths to the local devices, you are no longer
required to use other SATPs as you were in the earlier vSphere releases.
VMW_SATP_LOCAL supports the VMW_PSP_MRU and
VMW_PSP_FIXED path selection plug-ins, but does not support
VMW_PSP_RR.
VMW_SATP_DEFAULT_
AA
Generic SATP for active-active arrays.
VMW_SATP_DEFAULT_
AP
Generic SATP for active-passive arrays.
VMW_SATP_ALUA SATP for ALUA-compliant arrays.
For more information, see the VMware Compatibility Guide and the vSphere Command-Line Interface
Reference documentation.
Display SATPs for the Host
Use the esxcli command to list VMware NMP SATPs loaded into the system. Display information about
the SATPs.
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
To list VMware SATPs, run the following command:
esxcli storage nmp satp list
For each SATP, the output displays information that shows the type of storage array or system the SATP
supports. The output also shows the default PSP for any LUNs that use this SATP. Placeholder
(plugin not loaded) in the Description column indicates that the SATP is not loaded.
