Table 9. Table view information
Field Description
Health Shows the health of the component: OK, Degraded, Fault, N/A, or Unknown.
Type Shows the component type: enclosure, disk, power supply, controller module, network port, host
port, expansion port, CompactFlash card, or I/O module (expansion module).
Enclosure Shows the enclosure ID.
Location Shows the location of the component.
● For an enclosure, the location is shown in the format Rack rack-ID.shelf-ID. You can set the
location through the CLI set enclosure command.
● For a disk, the location is shown in the format enclosure-ID.disk-slot.
● For a power supply or I/O module, the locations Left, Left-Middle, Middle, Right-Middle, and
Right are as viewed from the rear of the enclosure.
● For a host port, the location is shown as controller ID and port number.
Information Shows additional, component-specific information:
● For an enclosure, its FRU description and current disk count.
● For a disk, its description, capacity, and usage.
● Type is shown as either:
○ SAS – Enterprise SAS spinning disk.
○ SAS MDL – Midline SAS spinning disk.
○ SSD SAS – SAS solid-state disk.
● Usage is shown as either:
○ AVAIL – The disk is available.
○ GLOBAL SP – The disk is configured as a spare.
○
DEDICATED SP – The disk is configured as a dedicated spare.
○ pool-ID:tier name for disk groups that are part of a virtual pool or pool-ID: Linear for
disk groups that are part of linear pools. The disk is part of a 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.
○ LEFTOVR – The disk is part of a disk group that is not found in the system.
○ 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.
● For a power supply: its FRU description.
● For a fan: its rotational speed in r/min (revolutions per minute).
● For a controller module: its ID.
● For a network port: its IP address.
● For a host port:, one of the following values:
○ FC(L) – Fibre Channel-Arbitrated Loop (public or private)
○ FC(P) – Fibre Channel Point-to-Point
○ FC(-) – Fibre Channel disconnected
○ SAS – Serial Attached SCSI
○ iSCSI – Internet SCSI
● For an expansion port, either Out Port or In Port.
● For an I/O module, its ID.
Status
Shows the component status:
● For an enclosure: Up.
● For a disk:
○ 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 DSD 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 the Error status.
