Troubleshooting
You are using a
PowerVault MD3000
or PowerVault
MD3000i storage
array and one of the
following occurs:
• Unable to assign
the drive letter to
the snapshot virtual
disk.
• Unable to access
the snapshot virtual
disk.
• System Error Log
displays a warning
with event 59 from
partmgr stating
that the snapshot
virtual disk is a
redundant path of a
cluster disk.
The snapshot virtual
disk has been
erroneously mapped
to the node that does
not own the source
disk. Unmap the snapshot virtual disk
from the node not owning the source
disk, then assign it to the node that
owns the source disk. For more
information, see "Using Advanced
(Premium) PowerVault Modular Disk
Storage Manager Features" section of
the Dell Failover Cluster Hardware
Installation and Troubleshooting
Guide for the specific storage array
on the Dell Support website at
support.dell.com .
You are using a
PowerVault MD3000
or PowerVault
MD3000i storage
array in a
non-redundant
configuration. The
Recovery Guru in the
Modular Disk Storage
Manager Client
reports that the
virtual disks are not
on the preferred
controller, and the
enclosure status LED
is blinking amber. The NVSRAM for the
non-redundant
configuration has not
been loaded. For PowerVault MD3000 storage
array, load the correct NVSRAM for
the non-redundant configuration.
