The O/S AIX 6. is from the local disks of VIO.
Local Disks of VIO_1 Server has been assigned to LPARs
Also, does anyone know if there is load balancing option available for VIO
Two VIO servers and One Lpar
can there be a load balancing ?
Thanks

mp_setlogicalunitloadbalancetype
MP_SetLogicalUnitLoadBalanceType(3MPAPI) Common Multipath Management Library Functions MP_SetLogicalUnitLoadBalanceType(3MPAPI)
NAME
MP_SetLogicalUnitLoadBalanceType - set a load balancing policy
SYNOPSIS
cc [ flag... ] file... -lMPAPI [ library... ]
#include <mpapi.h>
MP_STATUS MP_SetLogicalUnitLoadBalanceType(MP_OID logicalUnitoid,
MP_LOAD_BALANCE_TYPE loadBalance);
PARAMETERS
logicalUnitOid The object ID of the multipath logical unit.
loadBalance The desired load balance policy for the specified logical unit.
DESCRIPTION
The MP_SetLogicalUnitLoadBalanceType() function sets the multipath logical unit's load balancing policy. The value must correspond to one
of the supported values in MP_PLUGIN_PROPERTIES.SupportedLogicalUnitLoadBalanceTypes.
RETURN VALUES
MP_STATUS_INVALID_OBJECT_TYPE
The logicalUnitOid does not specify any valid object type. This is most likely to happen if an uninitialized object ID is passed to the
API.
MP_STATUS_INVALID_PARAMETER
The loadBalance is invalid or logicalUnitOid has a type subfield other than MP_OBJECT_TYPE_MULTIPATH_LU.
MP_STATUS_OBJECT_NOT_FOUND
The logicalUnitOid owner ID or object sequence number is invalid.
MP_STATUS_SUCCESS
The operation is successful.
MP_STATUS_FAILED
The specified loadBalance type cannot be handled by the plugin. One possible reason for this is a request to set MP_LOAD_BAL-
ANCE_TYPE_PRODUCT when the specified logical unit has no corresponding MP_DEVICE_PRODUCT_PROPERTIES instance (i.e., the plugin does not
have a product-specific load balance algorithm for the LU product).
MP_STATUS_UNSUPPORTED
The implementation does not support the API.
