This page was deprecated on 18 August 2025. Refer to the SANsymphony WebHelp for the latest and updated documentation.

Creating the SATP Rule

Add the following SATP rule using the ESXi host’s console:

esxcli storage nmp satp rule add -V DataCore -M 'Virtual Disk' -s VMW_SATP_DEFAULT_AA -P VMW_PSP_MRU

Configuration Notes

• Hosts must not have the ALUA setting enabled in the SANsymphony console. See Changing multipath or ALUA support settings for hosts.
• When using MRU, the ‘Preferred DataCore Server’ setting is ignored. Please refer to VMware's own documentation on how to configure 'active' paths when using MRU PSP.
• If you are trying to modify an existing SATP rule, please follow the instructions on VMware Path Selection Policies.
