HP 3PAR VMware ESX Implementation Guide
ESXi 5.x example
For persona 11:
For persona 6:
ESX/ESXi 4.x example
# esxcli nmp satp listrules | grep -i 3par
VMW_SATP_ALUA 3PARdata VV

Show Device Information
To show device information, use the commands in the following examples:
ESXi 5.x example
# esxcli storage nmp device list
naa.50002ac0000a0124
Device Display Name: 3PARdata iSCSI Disk (naa.50002ac0000a0124)
Storage Array Type: VMW_SATP_ALUA
Storage Array Type Device Config: {implicit_support=on;explicit_support=on;
explicit_allow=on;alua_followover=on;{TPG_id=256,TPG_state=AO}}
Path Selection Policy: VMW_PSP_RR
Path Selection Policy Device Config: {policy=rr,iops=1,bytes=10485760,useANO=0;lastPathIndex=1:
NumIOsPending=0,numBytesPending=0}
Path Selection Policy Device Custom Config:
Working Paths: vmhba3:C0:T1:L73, vmhba2:C0:T0:L73, vmhba2:C0:T1:L73, vmhba3:C0:T0:L73
ESX/ESXi 4.x example
The command is the same for ESX/ESXi 4.x. The output shown is for ESX 4.0:
# esxcli nmp device list
naa.50002ac000b40125
Device Display Name: 3PARdata Fibre Channel Disk (naa.50002ac000b40125)
Storage Array Type: VMW_SATP_DEFAULT_AA
Storage Array Type Device Config:
Path Selection Policy: VMW_PSP_RR
Path Selection Policy Device Config: {policy=rr,iops=1000,bytes=10485760,useANO=0;lastPathIndex=3:
NumIOsPending=0,numBytesPending=0}
Working Paths: vmhba5:C0:T0:L25, vmhba5:C0:T1:L25, vmhba4:C0:T0:L25, vmhba4:C0:T1:L25
For ESX 4.1, the iops will be 1 for the device list output shown above.
Script Alternative for Path Policy Changes on Storage Devices without a Host Reboot
If a reboot of the ESX/ESXi host to affect path policy changes through SATP on a large number of
existing, previously presented storage devices is not desirable, the path policy changes on a batch
of LUNs can be made by scripting esxcli commands.
Create a script that uses the following commands:
1. List all the HP 3PAR devices present on the host:
