This may sound like an absolute rookie question, and it is.
I have been working on Migrating our HP and Solaris servers to the new EMC SAN and know the routines backwards.
Now we've suddenly got a new IBM server and I don't even know how to check if it is connected to the switch.

Hi
I would like to ask what the benefits are of changing from RDAC to MPIO when connecting to a DS4000 on AIX 5.3? I have heard that IBM MPIO "might" support more than 1 active path to a LUN when connecting to a DS4800 through more than 1 host connection on the same AIX client. I understand that... (8 Replies)

Hi folks,
does anybody have a link to a documentation how to implement native MPIO on AIX? We are using EMC PowerPath and Datacore SanSymphony/Cambex for this so far and I wasn't able to find a good description on that topic. All I know so far is that mkpath, chpath and lspath are used to... (3 Replies)

Hi,
I was trying to uninstall the native MPIO driver on the AIX 6.1 machine we have in our lab and ran into a whole bunch dependent filesets initially. I deleted the disks, fcsX, fscsiX, fcnetX and tried again, but ran into the same error.
Subsequently, I figured out that the OS disks in... (4 Replies)

Hi All..
On to a new implementation with AIX 7.1 san boot from EMC disks (Using NPIV). Anyone played with this recently?
Wondering if we need PowerPath on the AIX clients or has native MPIO matured to replace it. Thoughts?
Thanks

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.
