Replacing a drive carrier module

Procedures for the removal and installation of a drive carrier module.

A disk drive module consists of a disk in a carrier or sled. Disk Drive in Carrier (DDIC) modules are hot-swappable, which means they can be replaced without halting I/O to the disk groups, or powering off the enclosure. The new disk must be of the same type, and possess capacity equal to or greater than the one being replaced. Otherwise, the storage system cannot use the new disk to reconstruct the disk group. Remove the top lid “A” to access DDICs. See Figure 1 for enclosure lid locations and labeling. Reattach top lid “A” when the procedure is completed. If accessing DDICs in disk slots 96–105, remove top lid “B”, and reattach it when the procedure is completed. See also Figure 3 for disk slot indexing.

CAUTION:

Removing a disk drive module impacts the airflow and cooling ability of the enclosure. If the internal temperature exceeds acceptable limits, the enclosure may overheat and automatically shut down or restart. To avoid potential overheating, wait 20 seconds to allow the internal disks to stop spinning, then insert the new disk drive module.

See CAUTION bullets regarding electrostatic discharge and anti-static protection in the ESD precautions section.

Tip: The illustrations show disk module replacement within the drive slots as you view the enclosure top panel. See also Figure 3 for disk drive slot numbering.
