show disks


Description	Shows information about all disks or disk slots in the storage system. The command will show information about all installed disks by default, or you can use parameters to filter the output. NOTE:In console format, to aid reading, disks are sorted to display in order by enclosure and disk number. In API formats, output is not sorted because it is expected to be manipulated by a host application.
Minimum role	monitor

Disabled: SMART is disabled for all disks in the system and will be disabled for new disks added to the system. Speed (kr/min) 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. Usage Shown by default or by the detail parameter. AVAIL: Available. DEDICATED SP: The disk is a spare assigned to a linear disk group. FAILED: The disk is unusable and must be replaced. Reasons for this status include: excessive media errors, SMART error, disk hardware failure, or unsupported disk. GLOBAL SP: The disk is a global spare. LEFTOVR: The disk is a leftover. LINEAR POOL: The disk is a member of a linear disk group. UNUSABLE: The disk cannot be used in a disk group. Possible reasons include: The system is secured and the disk is data locked with a different passphrase. The system is secured/locked (no passphrase available) and the disk is data/locked. The system is secured and the disk is not FDE capable. UNUSABLE: The disk cannot be used in a disk group because the disk is from an unsupported vendor. VDISK: The disk is a member of a linear disk group. VDISK SP: The disk is a spare assigned to a linear disk group VIRTUAL POOL: The disk is a member of a disk group in a virtual pool. Vdisk (v2) Shown by default or by the detail parameter. The name of the disk group that contains the disk. Vendor Shown by default and by any parameter except temp. The vendor of the disk.
