MSA 2040 SMU Reference Guide

Viewing information about an enclosure 115
• How Used.
• AVAIL: Available.
• FAILED: The disk is unusable and must be replaced. Reasons for this status include: excessive media errors;
SMART error; disk hardware failure; unsupported disk.
• GLOBAL SP: Global spare.
•LEFTOVR: Leftover.
• UNUSABLE: The disk cannot be used in a vdisk because the system is secured and the disk is not
FDE-capable, or because the disk is locked to data access.
• VDISK: Used in a vdisk.
• VDISK SP: Spare assigned to a vdisk.
• Type.
• SAS: Enterprise SAS.
•SAS MDL: Midline SAS.
• sSAS: SAS SSD.
• Vendor.
• Model.
• Size.
• Speed (kr/min).
• Transfer Rate. The data transfer rate in Gbit/s. Some 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.
• Revision. Disk firmware revision number.
• Serial Number.
• Current Job.
• DRSC: Disks in the vdisk are being scrubbed.
• EXPD: The vdisk is being expanded.
• INIT: The vdisk is being initialized.
• RCON: The vdisk is being reconstructed.
• VRFY: The vdisk is being verified.
• VRSC: The vdisk is being scrubbed.
• SMART. Shows whether Self-Monitoring Analysis and Reporting Technology is enabled. For more information, see
"Configuring SMART" (page 49).
• Current Owner. For the disk’s vdisk, either the preferred owner during normal operation or the partner controller
when the preferred owner is offline.
• Drive Spin Down Count. How many times the disk has been spun down.
• SSD Life Remaining.
• For an SSD this property shows the percentage of disk life remaining, represented by a color-coded bar
graph:
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%, and 0%.
• For a non-SSD this property shows N/A.
