Welcome to the Unity 3.5-inch disk drive replacement demonstration. To begin, we’re going to log in to Unisphere using the admin account. As we can see on the Unity dashboard, in the system health window there are no hardware issues reported. Since we don’t have an actual faulted drive, let’s navigate to the System View page to pick one. Click on the “System View” link, select the “Enclosures” tab, and then click on the DAE.
Let’s look at the front view. In this case, the DAE, or disk-array enclosure, contains 15 3.5-inch disk drives. Let’s choose drive number 14. Identify the faulted drive by the amber fault LED, pull the latch on the drive up and partially remove it from its slot and wait 30 seconds for it to stop spinning, then pull the drive completely out of the slot.
Align the replacement drive with the guides in the slot. With the drive carrier latch fully opened, gently push it into the slot. The latch begins to rotate downward when its tabs meet the enclosure. Push the handle down to engage the latch. The drive’s activity light flashes to reflect the spin-up sequence.
To check the replacement drive status, log back in to Unisphere. Begin by navigating to the System View. Click on the “Enclosures” tab and then select the DAE. Now select the front view. Here we can see that disk 14 is operating normally. This completes the Unity 3.5-inch disk drive replacement demonstration.
