Win2008R2 MPIO with Powerstore 1200T

Hi All,

We have a legacy Cisco UCSC-C220-M3S server running Windows 2008R2. It hosts a smallish SQL 2008R2 instance that links to another 2008R2 virtual server that contains about 8TB (and growing) of mostly incompressible content (PDFs, JPGs, etc). This application is owned outside our IT department, so it has been very difficult to get traction to move it to a supported OS (which includes an application upgrade), but they claim (again) that it'll happen this year. It'll be rebuilt as virtual when we cross that bridge.

This Cisco server has two FC ports, each port has 4 paths through two Brocade 300 switches to an EMC vNXe3200 SAN. The 2008R2 OS correctly shows only two SAN volumes in Disk Management.

We bought a pair of Brocade 6620B switches, and a Powerstore 1200T, to replace the aforementioned hardware. We need to get the SAN volumes used by this Cisco server migrated to the new SAN.

Last night a vendor had me move one fiber cable from the old sw2 to the new sw2. He eventually got the volumes displaying in Windows Disk Management, but they showed all four paths instead of just two. After about 2 hours of fighting it, we rolled back. We are wondering if there is a compatibility issue we're missing or how else we can make progress on moving this data to the new SAN.

Thanks for your help.

The Windows 2008/R2 MPIO feature is not compatible with the PowerStore appliance.  According to the EE/Dev team, even in early versions of PowerStore OS, although we had limited support for 2008/R2, MPIO and PowerPath were never intended to be compatible or validated.

Hi,

Thanks for your question.

This may be helpful. https://dell.to/4dlSYzr It may also be a limitation of server 2008, since 2012 is the oldest validated Windows for Powerstore.

Let us know if you have any additional questions.

Hi Josh, 

I guess I don't have my notifications for this topic setup correctly to receive notifications for new posts. We worked with a Dell Senior Engineer last night and he said he'd check with the dev team.
