-MaxSessionsPerEntireVolume=1-12
-DefaultLoadBalancing=LQD|RR|FO
-UseMPIOForSnapshots=yes|no
-UseIPv4 | -UseIPv6
-ClearDeviceLBPolicy
-MinAdapterSpeed=100|1000|10000 (as Mbps)
The following table describes the command parameters.
Table 8. List or Modify MPIO Settings Command Options
Parameter Argument Description
MaxSessionsPerVolumeSlice= 1- 4 Designates the maximum number of connections that MPIO
should use per volume per member.
MaxSessionsPerEntireVolume= 1- 12 Designates the maximum number of connections that MPIO
should use per volume for all members.
DefaultLoadBalancing= LQD|RR|FO Specifies the default load-balancing policy for MPIO as Least
Queue Depth (LQD), Round Robin (RR), or Failover Only (FO).
This change does not affect existing device load balancing
policy, unless the ClearDeviceLBPolicy parameter is also
specified.
MinAdapterSpeed= 100|1000|10000 Specifies that MPIO will only use NICs that meet the minimum
speed specified in Mbps, if at least two NICs meet the speed.
UseMPIOForSnapshot= yes | no Specifies whether MPIO should be used for snapshots.
UseIPv4 Specifies that MPIO will use IPv4 IP addresses only. This
parameter is mutually exclusive with the UseIPv6 parameter.
UseIPv6 Specifies that MPIO will use IPv6 IP addresses only. This
parameter is mutually exclusive with the UseIPv4 parameter.
ClearDeviceLBPolicy Specifies that if the default load-balancing policy is changed,
then the load-balancing policies for individual devices should be
cleared if they are not set to use the default.
List Included and Excluded Subnets for MPIO
Use the rswcli ListMPIO command to list subnets that are included or excluded for MPIO.
The default output for this command lists the adapters available. The state of each adapter is shown following the adapter
name, either included or excluded. Optionally, the rules used to generate the include and exclude lists can also be displayed.
The command syntax is as follows:
rswcli ListMPIO [IncludeOnly | ExcludeOnly] [-Detail]
The following table describes the command parameters.
NOTE: These parameters apply to the adapter list only. They do not apply to the rules list.
