Service manual

Chapter 4 Service 4-3
While there is no Solaris system software that provides hot-plug functionality to
shield the operating system from the physical removal and replacement of a hard
drive, there are several scenarios where a disk drive can be safely removed or added
to the media tray as long as the software framework managing the disk drives in the
media tray is taken into account.
In general, hot-plug reconfiguration operations involve three stages:
1. Preparing for hot-plug reconfiguration
2. Adding, replacing, or removing a hard drive
3. Reconfiguring the operating environment
Two specific cases where the hot-plug feature may be useful include:
■ Adding a drive to a system to increase storage capacity
■ Replacing a faulty drive while the system is running
4.2.2 Adding Hard Drives
This procedure is for adding upper and lower hard drives.
Note – For hard drives on sled assemblies, see Section 4.3.1 “Removing a Sled
Assembly” on page 4-15 to remove an existing sled assembly, and Section 4.3.2
“Replacing a Sled Assembly” on page 4-16 to install (add) a hard drive on a sled
assembly. Then proceed with the procedures in Section 4.2.2 “Adding Hard Drives”
on page 4-4, starting with step 4.
1. Remove the front bezel from the media tray.
2. Select a slot for the new drive.
The preferred loading order is the same as the SCSI address order.
3. Install the drive.
a. Attach an antistatic wrist strap to your wrist and to the media tray chassis.
b. With the bracket lever opened, insert the drive into the drive bay, aligning the
connector on the drive with the connector on the backplane.
c. Slowly and gently push the drive in until the metal drive lever contacts the
drive tray rib.
d. Press the drive bracket lever closed until it latches.
e. Remove the wrist strap.
