Table 26 drives properties (continued) Name Type Description index rpm size size-numeric transfer-rate transfer-ratenumeric attributes attributesnumeric virtual-diskserial enclosure-wwn status usage uint32 For internal use only. uint32 The speed of a spinning disk, in thousands of revolutions per minute, as specified by the disk vendor. string Disk capacity, formatted to use the current base, precision, and units. string Unformatted size value in 512-byte blocks. string Disk data transfer rate in Gbit/s. It is normal behavior for the rate to vary. • 1.5 • 3.0 • 6.0 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. string For internal use only. string string Shows which controller a single-ported disk is connected to. • A: Controller A. • B: Controller B. For internal use only. string Serial number of the disk's vdisk, if any. string string string Enclosure WWN. Disk status. • 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. Shows the disk's usage. • AVAIL: The disk is 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: The disk is a global spare. • LEFTOVR: The disk is a leftover and can be reused after its metadata is cleared. • VDISK: The disk is used in a vdisk. • VDISK SP: The disk is a spare assigned to a vdisk. drives 391
