Display Disk Reliability Details
Disk reliability information details the hardware state of each disk. The information is generally for
the use of Data Domain support staff when troubleshooting.
Disk
is the disk ID number, from 1 (one) to 15.
The
ATA Bus Soft Err
column shows uncorrected raw UDMA CRC errors.
The
Command Timeouts
counts times that the operating system SCSI midlayer registers that a
command timed out.
Command Faults
columns shows counts of commands that the operating system SCSI midlayer
registers as leading to read failures, write failures, and other command failures.
The
Drive Soft Err
columns show the number of errors corrected by the disk’s software error
correction control. The
Soft
column is the number of off track errors. The
Err
column is the number
of soft ECC errors.
Awaiting Realloc
shows the number of sectors on a drive that have returned at least one error, but
that are not yet confirmed as bad.
Already Realloc
indicates the end of the useful disk lifetime when the number of reallocated sectors
approaches the vendor-specific limit. The limit is 2000 for Western digital disks and 2000 for
Hitachi disks. Use the
disk show config
command to display the disk vendor.
Temp
shows the current temperature of each disk in degrees centigrade. The allowable temperature
range for disks is from 5 degrees centigrade to 58 degrees centigrade.
Display
Use the
disk show reliability data
operation or click
Disks
in the left panel of the DDR
Manager to see the reliability statistics.
