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
