HP-UX HotPlug Disk Drive Replacement
HP-UX HotPlug Disk Drive Replacement
The internal disk drives (two) are located at the front left side of the server (behind the bezel). When proper
software and hardware procedures are followed, internal disk drives can be removed and replaced while the
server is running.
NOTE MPE/iX does not support hotplug. Do not use these procedures on HP e3000 servers.
The procedures in this section are in two parts: physically replacing the device in the server and performing
the HotPlug software procedure.
The replacement disk drive must be the same product ID as the disk drive that is being replaced.
HotPlug Hardware Procedure
Be sure that all the software procedures in the Disk Drive Removal section have been performed prior to
starting these steps.
To install a disk drive from the server, perform the following steps:
Step 1. Remove the front bezel.
Step 2. On the left side of the front of the server you will see a door with a spring-loaded latch holding it
shut. Open the door to expose the disk drive slots.
Step 3. Align the drive and carefully slide it completely into the selected slot with the extraction levers out.
Step 4. Fold the extraction levers in to engage and lock the disk drive in place.
Step 5. Close the door and engage the spring-loaded latch to keep it shut.
The following photograph shows a HotPlug disk installed in the disk housing.
