Figure 25. Device List Command Output Adding an SATP Claim Rule to Enable ALUA and Change the Multipath Policy to Round Robin To create the new claim rule, use the following command: #esxcli storage nmp satp rule add -s VMW_SATP_ALUA -V DELL -M array_model -c tpgs_on -P VMW_PSP_RR -e "Dell ALUA Claim Rule" Valid values for array_model are MD32xx, MD32xxi, MD36xxi or MD36xxf. This command creates a new entry for the VMW_SATP_ALUA rule for any LUN matching the vendor ID (-V) and model ID (-M) you specify. It also assigns the default path selection policy to round robin (-P VMW_PSP_RR). NOTE: There are different methods to manage SATP claim rules. Your environment may require different parameters to enable ALUA support. Refer to the VMware Knowledge Base for additional information. To verify that the new claim rule was created successfully, repeat the esxcli storage nmp device list command: Figure 26. Device List Command Output Following New Rule Creation Networking Configuration for Fibre Channel and iSCSI Storage (ESX/ESXi 4.x only) The Dell MD3600i-series and MD3600f-series storage arrays are not listed in the ESX/ESXi 4.x SATP (Storage Array Type Plug-in) driver. Therefore, both storage array product IDs must be manually added to the SATP to properly configure failover. Configuring the network manually creates a VMkernel port and maps it to a physical network interface card (NIC) capable of handling the specific data traffic. Depending on the number of physical NICs that you use, the networking setup can be different. NOTE: These steps are not required if you are using ESX/ESXi 5.0. Connecting a Dell MD3600i-Series or MD Dense iSCSI Storage Array If using a Dell MD3600i-series or MD Dense iSCSI storage array with ESX/ESXi 4.x, run the following commands before mapping any virtual disks from the iSCSI storage array to the host.

Device List Command Output
Adding an SATP Claim Rule to Enable ALUA and Change the Multipath Policy to Round Robin
To create the new claim rule, use the following command:
#esxcli storage nmp satp rule add -s VMW_SATP_ALUA -V DELL -M
array_model
-c
tpgs_on -P VMW_PSP_RR -e “Dell ALUA Claim Rule”
Valid values for
array_model
are
MD32xx, MD32xxi, MD36xxi
or
MD36xxf.
This command creates a new entry for the VMW_SATP_ALUA rule for any LUN matching the vendor ID (
-V
)
and model ID (
-M
) you specify. It also assigns the default path selection policy to round robin
(
-P VMW_PSP_RR
).
NOTE:
There are different methods to manage SATP claim rules. Your environment may require different
parameters to enable ALUA support. Refer to the VMware Knowledge Base for additional information.
To verify that the new claim rule was created successfully, repeat the
esxcli storage nmp device list
command:
