Location
The disk location in the format disk_enclosure-ID.slot-number.
Serial Number
The serial number of the disk.
Pwr Hrs
The total number of hours that the disk has been powered on since it was manufactured. This value is stored in disk metadata and is updated in 30-minute increments.
Bps
The data transfer rate, in bytes per second, calculated over the interval since these statistics were last requested or reset. This value will be zero if it has not been requested or reset since a controller restart.
IOPS
The number of input/output operations per second, calculated over the interval since these statistics were last requested or reset. This value will be zero if it has not been requested or reset since a controller restart.
Reads
The number of read operations since these statistics were last reset or since the controller was restarted.
Writes
The number of write operations since these statistics were last reset or since the controller was restarted.
Data Read
The amount of data read since these statistics were last reset or since the controller was restarted.
Data Written
The amount of data written since these statistics were last reset or since the controller was restarted.
Lifetime Read
The amount of data read from the disk in its lifetime.
Lifetime Written
The amount of data written to the disk in its lifetime.
Reset Time
Date and time, in the format
year-month-day hour:minutes:seconds , when these statistics were last reset, either by a user or by a controller restart.
Live, error-stats
Location
The disk location in the format disk_enclosure-ID.slot-number.
Serial Number
The serial number of the disk.
SMART port#
The number of SMART events recorded.
Time port#
The number of timeouts accessing the disk.
NResp port#
The number of times the disk did not respond.
Spin port#
The number of attempts by the storage system to spin up the disk.
Med port#
The number of media errors generated by the disk, as specified by its manufacturer.
NMed port#
The number of other errors generated by the storage system, or generated by the disk and not categorized as media errors.
BAsgn port#
The number of times blocks were reassigned to alternate locations.
BBlk port#
The number of bad blocks encountered.
Historical
Durable ID
The disk ID in the format disk_enclosure-number.disk-number.
