Most Recently Used (MRU) PSP

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.
