Chapter 12 Hard Disk Drive (HDD) Replacement 12-3
12.2 Active Replacement
The procedure for active replacement is as follows.
1. Unlock and open a door of the server.
For details, see Chapter 5.
Caution – Before touching FRU or the dummy (filler) unit, see Section 1.4,
“Antistatic Precautions” on page 1-6 and be sure to wear the antistatic wrist strap.
Failure to do so might result in serious damage to operating domains.
2. Prepare for the replacement of the target HDD.
From the OS, execute the cfgadm -a command to verify Ap_Id.
Stop the use of HDD by the application and disconnect the HDD from the OS. The
procedure of disconnecting the HDD from the OS varies depending on if you are
using the disk mirroring software or other supporting software. When you are not
using such kind of software, you can use the cfgadm command to disconnect the
target from the OS. When you are using the above software, see the manual of
that software for how to disconnect the disk.
The READY LED (green) of the HDD is turned off.
3. Blink the CHECK LED of the HDD to be replaced.
From the OS, execute the cfgadm -x led=fault,mode=blink <Ap_Id>
command.
4. Connect the clip of the antistatic wrist strap and of the antistatic mat to the
server grounding port. See Section 1.4, “Antistatic Precautions” on page 1-6.
5. Ensure that the metallic underside of the wrist strap is in direct contact with
your skin. The wrist strap should be snug around the wrist so that it does not
rotate. See Section 1.4, “Antistatic Precautions” on page 1-6.
Caution – Before handling FRUs, be sure to connect the clip of the antistatic wrist
strap and of the antistatic mat to the server grounding port, and attach the band of
the wrist strap to one of your wrists. Place the FRUs on the grounded antistatic mat.
Failure to take these antistatic measures might result in serious damage.
