SMART Error
Table 6-4 describes issues related to the Self-Monitoring Analysis and Reporting Technology (SMART).
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 could indicate hardware failure, see the
Dell OpenManage Storage Management documentation.
A physical disk becomes
inaccessible during a
reconstruction process on a
redundant virtual disk that has
a hot spare.
The rebuild operation for the
inaccessible
physical disk starts automatically after
the reconstruction is completed.
A physical disk is taking longer
than expected to rebuild.
A physical disk takes longer to rebuild when under high stress. For example, there is
one rebuild input/output (I/O) operation for every five host I/O operations.

Problem Suggested Solution
A SMART error is detected on
a physical disk in a redundant
virtual disk.
Perform the following steps:
1
Force the physical disk offline.
2
Replace it with a new physical disk of equal or higher capacity.
3
Perform a rebuild.
See "Performing a Manual Rebuild of an Individual Physical Disk" on page 67 for
rebuild procedures.
A SMART error is detected
on a physical disk in a
non-redundant virtual disk.
Perform the following steps:
1
Back up your data.
2
Delete the virtual disk.
See "Deleting Virtual Disks" on page 67 for information on deleting a virtual disk.
3
Replace the affected physical disk with a new physical disk of equal or higher
capacity.
4
Recreate the virtual disk.
See "Setting Up Virtual Disks" on page 58 for information on creating virtual disks.
5
Restore the backup.
