Sun Microsystems T6320 service manual Rules for Hot-Plugging, Removing a Hard Drive

3.2.1Rules for Hot-Plugging

To safely remove a hard drive, you must:

■Prevent any applications from accessing the hard drive.

■Remove the logical software links.

Hard drives cannot be hot-plugged if:

■The hard drive provides the operating system, and the operating system is not mirrored on another drive.

■The hard drive cannot be logically isolated from the online operations of the server module.

If your drive falls into these conditions, you must shut the system down before you replace the hard drive. See Section 4.2.2, “Shutting Down the System” on page 4-3.

3.2.2Removing a Hard Drive

1.Identify the physical location of the hard drive that you want to replace (FIGURE 3-2).

2.Type the Solaris OS commands required to stop using the hard drive.

The exact commands required depend on the configuration of your hard drives. You might need to unmount file systems or perform RAID commands.

One command that you may use to take the drive offline is cfgadm. For more information see the Solaris cfgadm man page.

3.Verify that the blue Drive Ready to Remove LED is illuminated on the front of the hard drive.
