Boot Crashdump Save to Disk Behavior

If you system is configured to write crashdumps after system failures,
and the host is configured to boot from the array, you will be able to
successfully save the crashdump only on the original available boot
device path on which the system started. This is a Windows
limitation, and installing PowerPath will not affect this behavior. At
the time a system crash is to be written to disk, Windows has already
saved the original boot path, and PowerPath cannot redirect the
crashdump file (

MEMORY.DMP

) to an alternative available device. If

you have a configuration for which you want to capture a
crashdump, you should ensure that the original primary boot path is
available at the time of the crash.

Boot-from-SAN with MSCS

The current installation, configuration and limitation information for
boot-from-SAN with Microsoft Clustering (MSCS) configurations can
be found in the latest EMC Host Connectivity Guide for Windows.
Please also refer to the EMC Support Matrix for approved
boot-from-SAN MSCS configurations.
