Related Disks table
When you select a disk group in the Related Disk Groups table, the disks for it appear in the Related Disks table.
For selected disks, the Related Disks table shows the following information:
Table 14. Related Disks table
Field Description
Location Shows the location of the disk.
Health Shows the health of the disk: OK, Degraded, Fault, N/A, or Unknown.
Description Shows the disk type:
● SAS – Enterprise SAS spinning disk.
● SAS MDL – Midline SAS spinning disk.
● SSD SAS – SAS solid-state disk.
Size Shows the storage capacity of the disk.
Usage Shows how the disk is being used:
● LINEAR POOL – The disk is part of a linear pool.
● DEDICATED SP – The disk is a dedicated spare for a linear disk group.
● VIRTUAL POOL – The disk is part of a virtual pool.
● LEFTOVR – The disk is leftover.
● 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.
Disk Group Shows the disk group that contains the disk.
Status Shows the status of the 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 Error status.
● Unrecoverable – The disk is present but has unrecoverable errors.
To see more information about a disk in a disk group, select the pool for the disk group in the pools table, select the disk group
in the Related Disk Groups table, and then hover the cursor over the disk in the Related Disks table. The Disk Information panel
opens and displays detailed information about the disk.
