Chapter 8. Maintaining Units
134
A status column on the controller, unit, and drive information pages lets you
quickly see whether everything is working (OK), performing a task (such as
initializing, verifying, or rebuilding), or has a problem (error, degraded, or
warning).
The next figure illustrates how you can drill down to get additional detail
about units and drives in your system.
Figure 68. Drilling Down to Check Status Information
For some RAID levels (RAID 6, RAID 10, and RAID 50), a single RAID unit
may have more than one status. For example, part of the unit could be
rebuilding, while another part is degraded or initializing. When this is the
case, you will see both statuses listed at the top unit level. When you drill in to
see details, you will be able to see which the specific subunits or drives to
which the status applies.
For an explanation of unit and drive status, see:
• "Unit Statuses" on page 137
• "Drive Statuses" on page 138
If you use a supported enclosure with enclosure services, the LEDs on your
enclosure may also provide some status information. For details, see
"Enclosure Drive LED Status Indicators" on page 136.
