If you have configured recipients for SNMP traps or email alerts, they will be notified of a disk
failure. You can also use the GUI as follows:
• Go to the appropriate Hardware page to get the details for the device: Hardware — Storage
Clusters — Storage Cluster n — Drive Enclosure — Sub Enclosure (Drawer n) — Drives.
The disk fault LED (amber) will also be illuminated on the disk carrier.
Using the StoreOnce CLI
The following StoreOnce CLI commands can also be used to identify specific disk locations, to
walk through the hardware tree to identify the disk and enclosure and to flash the Beacon LED on

Replacing a hot plug disk in a disk enclosure
Important Safety information
WARNING! To reduce the risk of personal injury or damage to the equipment, ensure that only
one hard drive drawer is extended at a time.
Replacing a hard drive within the enclosure is an online activity, providing the following general
guidelines are observed:
• When the drawer is opened, the cooling fans in the enclosure will run at full-speed. This is
normal.
• Hard drives are sensitive to excessive vibration. Use care when opening and closing the
drawer.
• Never leave the drawer open for any length of time. It should be opened only for maintenance
and storage expansion.
• Verify that the drives are fully seated before closing the drawer.
• The drawer is fully closed when the fans slow down to their normal speed.
• The drawer should be closed with the handle in the released position.
NOTE: Remember to close the handle after closing the drawer
