1. Run the following command: # esxcli storage nmp satp rule add –s VMW_SATP_ALUA –V DELL –M array_PID -c
tpgs_on
Where, array_PID is your storage array model/product ID. To select the appropriate array_PID for your storage array, see the
following table.
Table 17. Array pids of different storage arrays
Storage Array array_PID
MD3400 MD34xx
MD3420 MD34xx
MD3800i MD38xxi
MD3820i MD38xxi
MD3800f MD38xxf
MD3820f MD38xxf
MD3460 MD34xx
MD3860i MD38xxi
MD3860f MD38xxf
2. Reboot your ESX-based host server.
Verifying ALUA on VMware ESXi
To verify that the SATP claim rule you set is added in VMware ESXi, run the following command for ESXi 5.x:
# esxcli storage nmp satp rule list –s VMW_SATP_ALUA
Verify that the claim rule for VMW_SATP_ALUA with the VID/PID = Dell/array_PID shows the tpgs_on flag specified.
Verifying if host server is using ALUA for MD
storage array
To confirm that the host server is using the ALUA plug-in, for ESXi 5.5, run the following command:
#esxcli storage nmp device list
The value for Storage Array Type must be VMW_SATP_ALUA on each MD Series storage array.
Setting round-robin load balancing policy on ESXi-
based storage arrays
NOTE:
Perform this procedure after you have enabled ALUA on VMware ESXi and verified if the host server is using
ALUA for the MD storage array. For more information, see Enabling ALUA On VMware ESX/ESXi and Verifying If Host
Server Is Using ALUA For MD Storage Array.
To set a round-robin load balancing policy on your ESXi-based host server:
1. For ESXi 5.x, run the following command:
# esxcli storage nmp satp set --default-psp VMW_PSP_RR --satp VMW_SATP_ALUA/VMW_SATP_LSI
2. Reboot your ESX-based host server.
