Removing and replacing a disk drive
To assess hard drive status, observe the SAS disk drive status LEDs. For an explanation of these
LEDs, see “Front panel LEDs” (page 15).
IMPORTANT: Before removing a SAS disk drive, perform a complete data backup.
If disk drive mirroring is enabled, you do not have to power down the server blade before
removing or replacing a SAS disk drive. If mirroring is not enabled, perform an OS shutdown
before removing a disk drive to protect data.
You are not required to remove the server blade from the enclosure to remove and replace a SAS
disk drive.
Removing a disk drive
1. Press the release button.
2. Open the ejector lever.
3. Slide the disk drive out of the drive cage.
CAUTION: Populate hard drive bays with a SAS disk drive or a hard drive blank. Operating
the server blade without a SAS disk drive or disk drive blank causes improper airflow and
cooling, which can lead to thermal damage.
Replacing a disk drive
See “Installing a hot-plug SAS disk drive” (page 25).
