Drive Hot-Plugging Guidelines
To safely remove a drive, you must:
■ Prevent any applications from accessing the drive.
■ Remove the logical software links.
Drives cannot be hot-plugged if:
■ The drive provides the operating system, and the operating system is not mirrored
on another drive.
■ The drive cannot be logically isolated from the online operations of the server
module.
If your drive falls into these conditions, you must shut down the Oracle Solaris OS
before you replace the drive. See “Shut Down the OS and Host (Commands)” on
page 57.

▼ Locate a Faulty Drive
This procedure describes how to identify a faulty drive using the fault LEDs on the
drive.
You can also use the diskinfo(1M) command to identify the slot in which a
particular drive is installed. Refer to the Administration Guide and to the Product Notes
for more information.
● View the drive LEDs to determine the status of the drive.
When the amber drive Service Required LED on the front of a drive is lit, a fault
has occurred on that drive.
See “Drive LEDs” on page 67.
