CAUTION These procedures should be performed only by qualified system administrator. Performing hot-plug operations on an active disk drive can result in data loss or corruption. Remove and Replace A Disk Module Remove a Disk Module CAUTION If the disk system is running and a disk module slot does not contain a disk drive or filler panel, the disk system will not cool properly and may overheat. If you are not replacing the disk module immediately, a filler panel must be installed to maintain proper cooling. Ensure that you have a replacement disk or filler panel before removing the disk module from the disk system unless you are returning a defective disk system. 1 Ensure there is no activity on the drives. If the Disk Drive LED for that disk module is flashing green, the disk drive is active. When the Disk Drive LED off, the disk module is either idle or completely off (see Table 1 on page 8). In this state, it is safe to remove the disk module.
