Windows 7 - SAN Failover
Asked By RyanMielk
08-Jun-07 01:51 PM
I'm having an issue where any time I try to create a protection group member
(or perform a consistency check) that has more than 3-4GB of data, my active
SAN controller reboots. The SAN fails over properly to the passive
controller, but DPM fails (Recovery point creation failed, or Replica is
inconsistent).
I am working with HP to get the latest firmware (I'm one behind), but has
anyone else seen this?

Ryan,
This seems like a hardware issue on the SAN. DPM does regular file system
operations and shouldnt be causing SAN controller reboots, etc in the first
place.
Can you get some one from your hardware vendor to take a look?

Kapil,
That's where I'm at right now. I'm going to update the firmware over the
weekend, and will report back here. I figured it wasn't a DPM issue, but was
curious if anyone else was reporting the problem, so that they may point me
in the right direction.
I read in another post that the RTM version of DPM will have capibilities to
copy from LUN to LUN without using the network, so I assume it has some SAN
fuctionality, and I didn't know if that functionality could be the cause. It
just seems odd that any other massive file copy doesn't cause the SAN to
fail, but DPM does. Weird.
I'll let you know what I find, and thanks again!
Ryan
