This video covers the process of replacing a faulted disk drive on an Avamar Gen4S Node. Before you begin, always ensure that you follow electrostatic discharge, or ESD, protection procedures when removing node components. Next, locate the hard drive that needs to be replaced using PuTTY to establish an SSH session to the node. For more information on how to do this, refer to the product documentation.
Now, locate the defective hard drive on the physical server. On Gen4S nodes, there are 12 drives and are numbered starting at zero, organized from the bottom left to the top right. Compare the label on the front of the defective and replacement hard drives to ensure that you are replacing the defective hard drive with the same equipment. On the defective hard drive, press the release button and then open the drive handle.
Pull the disk drive assembly from the node chassis until it is free of the drive bay and then set it aside. Before continuing ensure that the adjacent hard drives are fully seated. Trying to insert and lock a hard drive carrier next to a partially installed carrier can damage the adjacent carrier and render it unusable. With the handle on the replacement hard drive carrier in a fully open position, insert it into the drive bay until the carrier contacts the back plane, then close the handle to lock the drive in place. After inserting a hard drive, the RAID system automatically begins rebuilding the data.
Typically, the sled LED begins blinking while the hard drive is rebuilding. Confirm that the rebuild was successful by using PuTTY. The RAID rebuild process can take hours to complete. If the replacement disk drive status is not rebuilding, contact support.
