Conditions Actions
NOTE: Unresolved pinned cache can occur if
a virtual drive goes offline for any reason while
there is uncommitted cache data in memory.
NOTE: Clearing pinned cache means that the
pinned data is lost.
During a Shared PERC firmware flash, virtual drive
transitions to write-through until chassis is
recycled.
Allow the chassis reset to complete after the
firmware flash.
Virtual drives permanently transition to write-
through when Hardware failure occurs.
If hardware failure occurs, contact Dell technical
support. For more information, see the Getting
help.
In the event of a firmware mismatch, in the dual
fault tolerant Shared PERC 8 configurations, if one
controller has write-through capability and the
other does not, virtual drives on the controller with
write-through capability reverts to write-through.
Update the firmware such that both cards are
running the latest supported versions available.
NOTE: Ensure that you download the updated
firmware and driver version available at
dell.com/support/home.
NOTE: Virtual drives configured with forced write-back caching will not transition to write-through
in the above conditions.
SMART Errors
Self Monitoring and Reporting Technology (SMART) monitors the internal performance of all motors,
heads, and physical disk electronics and detects predictable physical disk failures.
NOTE: For information about where to find reports of SMART errors that can indicate hardware
failure, see the Dell Chassis Management Controller for Dell PowerEdge VRTX User’s Guide at
dell.com/esmmanuals.
SMART Error Detected On A Physical Disk In A Redundant Virtual Disk
Issue: A SMART error is detected on a physical disk in a redundant virtual disk.
Corrective
Action:
Perform the following steps:
1. Back up your data.
2. Physically remove the physical disk that detected the SMART error.
NOTE: If a hot spare is present, the rebuild starts with the hot spare after
the disk is removed.
3. Replace the disk with a new physical disk of equal or higher capacity.
4. Perform the Auto Replacement of a Virtual Disk operation.
NOTE: The Auto Replacement of Virtual Disk operation allows you to
copy data from a source physical disk of a virtual disk to a target physical
disk that is not a part of the virtual disk. For more information about the
Auto Replacement feature, see Auto Replacement Of A Virtual Disk
Member And Revertible Hot Spares.
