Customizing Round Robin Setup
You can use the esxcli storage nmp psp roundrobin commands to set round robin path options on a device
controlled by the VMW_PSP_RR PSP.
Specifying and Customizing Round Robin Path Policies
You can use esxcli storage nmp commands to set path policies. Specify one of the options listed in
“Connection Options for vCLI Host Management Commands,” on page 19 in place of <conn_options>.
1 Set the path policy to round robin.
esxcli <conn_options> storage nmp device set --device naa.xxx --psp VMW_PSP_RR
2 Specify when to switch paths.
You can choose the number of I/O operations, number of bytes, and so on. The following example sets
the device specied by --device to switch to the next path each time 12345 bytes have been sent along
the current path.
esxcli <conn_options> storage nmp psp roundrobin deviceconfig set --type "bytes" -B 12345 --
device naa.xxx
The following example sets the device specied by --device to switch after 4200 I/O operations have
been performed on a path.
esxcli <conn_options> storage nmp psp roundrobin deviceconfig set --type=iops --iops 4200 --
device naa.xxx
Retrieving Path Selection Settings
The esxcli storage nmp psp roundrobin deviceconfig get command retrieves path selection seings for a
device that is using the roundrobin PSP. You can specify the device to retrieve the information for.
Options Description
-d <device>
--device <device>
Device to get round robin properties for.
Specifying Conditions for Path Changes
The esxcli storage nmp psp roundrobin deviceconfig set command species under which conditions a
device that is using the VMW_PSP_RR PSP changes to a dierent path. You can use --bytes or --iops to specify
when the path should change.
Options Description
--bytes
-B
Number of bytes to send along one path for this device before the PSP switches to the next path. You can use
this option only when --type is set to bytes.
--device
-d
Device to set round robin properties for. This device must be controlled by the round robin (VMW_PSP_RR)
PSP.
--iops
-I
Number of I/O operations to send along one path for this device before the PSP switches to the next path.
You can use this option only when --type is set to iops.
