number of errors is counted from the time shown in the Service Hours item in the SCSI Physical
Drive section.
Having a large number of retry corrected errors does not necessarily indicate that the drive
is failing. However, as a precaution, you might wish to replace a drive that has an abnormally
high amount of errors when compared to similar drives. If this count increases rapidly, you
might need to replace the drive.
•
Seek Errors—Displays the number of seek errors that a physical drive detects. A seek error is
a seek that failed. The number of errors is counted over the time shown in the Service Hours
item in the SCSI Physical Drive section.
Seek errors occasionally occur. Having a large number of seek errors does not necessarily
indicate that the drive is failing. However, as a precaution, you might wish to replace a drive
that has an abnormally high amount of errors when compared to similar drives. If this count
increases rapidly, you might need to replace the drive.
•
ECC Corr Reads—Displays the number of times the drive used the ECC algorithm to recover
data for read requests. The number of errors is counted over the time listed in the Service
Hours item in the SCSI Physical Drive section.
ECC-corrected reads occasionally occur over time. Having a large number of ECC-corrected
errors does not necessarily indicate that the drive is failing. However, if a particular drive has
an abnormally high amount of ECC-corrected reads compared to similar drives, you might
replace the drive as a precaution. If this count increases rapidly, you might replace the drive.
Statistics Preserved
Indicates if and how physical drive statistics are preserved over a power cycle. The following
values are valid:
•
Preserved In NVRAM—The statistics are saved in non-volatile memory on the computer system.
•
Preserved On Disk—The statistics are saved on the disk drive.
•
Not Preserved - No CPU Support—The statistics are not saved across power cycles because
the hardware does not support this operation.
•
Not Preserved - No Free NVRAM—The statistics are not saved across power cycles because
all of the available non-volatile memory is in use.
•
Not Preserved - No Drive Support—The statistics are not saved across power cycles because
the physical drive does not contain a unique identifier to save it.
•
Not Preserved - No Software Support—The statistics are not saved across power cycles because
software does not provide support.
•
Unknown—The Storage Agents cannot determine the status. You may need to upgrade your
driver software or Storage Agents.
SCSI logical drives
Select a SCSI logical drive from the SCSI controller submenu to display the following information.
The following values are valid:
•
Status—Shows the status of the physical drive selected.
OK—The logical drive is in normal operation mode. No user action is required. ◦
◦ Failed—There are more failed physical drives than the fault tolerance mode of the logical
drive can handle without data loss.
◦ Unconfigured—The logical drive is not configured. Run the logical drive configuration
utility to configure the logical drive.
