TABLE 4-4
Hard Disk Drive Status Indicators
Indicator Color Notes
Power/Access Green This indicator lights when data is being read from or
written to the hard disk drive.
Service Required Yellow This indicator is lit when the system is running and
the hard disk drive is faulty.
OK-to-Remove Blue This indicator is lit to indicate that a hard disk drive
can be removed safely during a hot-plug operation.
Note – If a hard disk drive is faulty, the system Service Required indicator is also lit.
See “Front Panel Indicators” on page 9 for more information.
The hot-plug feature of the system’s internal hard disk drives enables you to add,
remove, or replace disks while the system continues to operate. This capability
significantly reduces system downtime associated with hard disk drive replacement.
Disk drive hot-plug procedures require software commands for preparing the
system prior to removing a hard disk drive and for reconfiguring the OS after
installing a drive. For detailed instructions, see Chapter 6 and also the Sun Fire V445
Server Service Manual.
