Differences in load-balancing technologies There are two primary types of load-balancing technologies referred to within Windows. This policy setting uses a single active path, and the rest of the paths are standby paths. The DSM chooses the least-weighted path from among the available paths. The DSM uses a standby path only when all of the active paths fail. have a peek here
Run application like diskmgmt.msc on the first host. 3. Steps to reproduce the issue: 1. Event ID 23 mpio - All paths have failed. \Device\MPIODisk5 will be removed. James I have been getting flat out iScsiPrt errors Event ID 27 (error) and 29 (error) -> Initiator could not find a match for the initiator task tag in the received http://www.eventid.net/display-eventid-17-source-mpio-eventno-9614-phase-1.htm
An example of English, please! If the DSM does support the device, it then indicates whether the device is a new installation, or is the same device previously installed but is now visible through a new Ashutosh, you mentioned this was something Microsoft was working on a fix for - is there any internal reference ID I can pass along to the Microsoft Support Engineer to point Is there anythine else that can be done to fix this?
Event ID 27 iScsiPrt - Initiator could not find a match for the initiator task tag in the received PDU. These redundant hardware paths are made up of components such as cabling, host bus adapters (HBAs), switches, storage controllers, and possibly even power. Thanks in advance. What Is Mpio Port drivers Port drivers manage different types of transport, depending on the type of adapter (for example, USB, iSCSI, or Fibre Channel) in use.
When the path that failed is reactivated or reconnected, the standby path can optionally return to standby if failback is turned on. Mpio Event Id 32 However, hotfixes on the Hotfix Request page are listed under both operating systems. The process of detecting failed paths and recovering from the failure is automatic, usually fast, and completely transparent to the IT organization. On Path 2, it is 0.
Hope this is of some use to you. - Liam Tuesday, May 24, 2011 10:29 PM Reply | Quote 0 Sign in to vote Have it solved the problem?

There is no particular order in which the DSMs are contacted, although the Microsoft DSM is always contacted last. Additionally, you can pre-configure MPIO so that when it detects a certain hardware ID, it defaults to a specific load-balancing policy setting. Mpio Windows 2012 R2
Some errors are temporary and can be recovered by using a recovery routine in the DSM; if recovery is successful, MPIO is notified and path validity is checked to verify that Event ID 34 iScsiPrt - A connection to the target was lost, but Initiator successfully reconnected to the target. CD Update the HP Onboard Administrator Update th HP Virtual Connect Modules Since following this ‘action plan' from HP the issue wasresolved - no re-occurance in 7 weeks. Check This Out Creating your account only takes a few minutes.
This method can be combined with MPIO-based fault tolerant failover and MPIO-based load balancing to further mitigate the risk of exposure to different types of hardware failures. How To Check Multipathing In Windows Are you an IT Pro? The following logs entries may be seen repeatedly in system32\sdd.log 05/24 21:03:03 Entering GmInterpretErrorEx(2225) MPD-005-600507680180870100000000000001AA @ 9de31780, Path-0 @ 9de31be0 05/24 21:03:03 GmInterpretError(2381) MPD-005-600507680180870100000000000001AA, Path-0, DsmId 9de31be0, NTSTATUS c0000185, Srb

Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to. Multipath bus drivers (mpio.sys) Bus drivers are responsible for managing the connection between the device and the host computer. The cluster works well, but one day we found that every 20-30 minute in the system event log on each node start to display error, warning and information events from MPIO this contact form Once or more paths have failed, thoughthe process is now complete.
Most multipath solutions for Windows today use the MPIO architecture and a DSM provided by the storage array manufacturer.
