Removal and replacement procedures 27
CAUTION: Remove or replace a hard drive only when the drive failure LED is amber. Data loss can occur if a
drive is removed when the drive online LED is green. See “Hot-plug SCSI hard drive LEDs” in Chapter 4,
“Server component identification,” for more information.
CAUTION: Remove or replace only one hard drive at a time. The controller relies on other drives to reconstruct
data on the replaced drive. Drive reconstruction is active when the drive online LED is flashing green.
To remove a hot-plug SCSI hard drive:
1. Press the release button to unlock the ejector lever on the hard drive.
2. Open the ejector lever to release the drive.
3. Slide the drive out of the cage.
