ESX/ESXi 4.0 GA - 4.0 Ux

NOTE:

• Though ESX 4.0 GA - 4.0 Ux supports custom SATP rules, the -P options for setting PSP (path

policy) within the custom rule are not supported. PSP must be defined within the default SATP

rules.

• ESX 4.0 GA - 4.0 Ux has a known issue wherein no attempt should be made to change iops

from its default value of 1000 (iops = 1000). If the iops value is changed, upon the next

host reboot, an invalid value for iops is picked up and iops are then unpredictable.

• If the custom rule is not created for ALUA, 3PARdata VV’s are claimed by the

VMW_SATP_DEFAULT_AA SATP rule even though the array persona is 11/VMware (ALUA

compliant array port presentation).

HP 3PAR SATP rules for use with persona 6/Generic-legacy (Active-Active array port presentation)

A “custom” SATP rule is not used. The PSP (path policy) is changed on the default active-active

SATP rule. The default multipath policy for VMW_SATP_DEFAULT_AA is VMW_PSP_FIXED (Fixed

path). The default is changed to the preferred PSP (path policy) of round-robin.

# esxcli nmp satp setdefaultpsp -s VMW_SATP_DEFAULT_AA -P VMW_PSP_RR
