CLI Guide

Shown by default, detail, fde, or perf parameter. The speed of a spinning disk, in thousands of
revolutions per minute, as specified by the disk vendor. For an SSD, 0 is shown.
SSD Life Remaining%
Shown by the detail parameter.
• 100%–0%: For an SSD, this field shows the percentage of disk life remaining. This value is polled every 5
minutes. When the value decreases to 20%, event 502 is logged with Informational severity. Event 502 is
logged again with Warning severity when the value decreases to 5%, 2% or 1%, and 0%. If a disk crosses
more than one percentage threshold during a polling period, only the lowest percentage will be reported.
• N/A: The disk is not an SSD.
Status
Shown by the encl parameter.
• Up: The disk is present and is properly communicating with the expander.
• Spun Down: The disk is present and has been spun down by the drive spin down feature.
• Warning: The disk is present but the system is having communication problems with the disk LED
processor. For disk and midplane types where this processor also controls power to the disk, power-on
failure will result in Error status.
• Error: The disk is present but is not detected by the expander.
• Unknown: Initial status when the disk is first detected or powered on.
• Not Present: The disk slot indicates that no disk is present.
• Unrecoverable: The disk is present but has unrecoverable errors.
• Unavailable: The disk is present but cannot communicate with the expander.
• Unsupported: The disk is present but is an unsupported type.
Temperature
Shown by the detail or temp parameter. The temperature of the disk.
Temperature Status
Shown by the temp parameter.
• OK: The disk sensor is present and detects no error condition.
• Warning: The disk sensor detected a non-critical error condition. The temperature is between the
warning and critical thresholds.
• Critical: The disk sensor detected a critical error condition. The temperature currently exceeds the
critical threshold.
• Unknown: The disk sensor is present but status is not available.
Tier
Shown by default or by the detail parameter.
• Performance: The disk is in the highest storage tier, which uses SSDs (high speed).
○ Standard: The disk is in the storage tier that uses enterprise-class spinning SAS disks (10k/15k
RPM, higher capacity).
○ Archive: The disk is in the lowest storage tier, which uses midline spinning SAS disks (<10k RPM,
high capacity).
○ Read Cache: The disk is an SSD providing high-speed read cache for a storage pool.
Total I/Os
Shown by the perf parameter. The total number of I/O operations (reads and writes).
Transfer Rate
Shown by the detail parameter. The data transfer rate in Gbit/s. A footnote indicates that it is normal
behavior for the rate to vary. ome 6-Gbit/s disks might not consistently support a 6-Gbit/s transfer rate. If
this happens, the controller automatically adjusts transfers to those disks to 3 Gbit/s, increasing reliability and
reducing error messages with little impact on system performance. This rate adjustment persists until the
controller is restarted or power-cycled.
