Appendix A Replacing and Upgrading FRUs
A.1 Installing or Removing Hard Disk Drives
Before you install or replace drives, plan where you will be placing the disk drives. For more
information, see Figure 2-4.
Do not mix SAS and SATA drives in the same storage system, due to timing
differences and rotational vibration issues from different drive types.
To install a drive, use the following procedure:
1.
Identify an available drive slot in the storage array.
2.
Select the right type of drive for this drive slot and assemble it into the drive carrier as
described in Section 3.5.
3.
Hold the drive carrier so the LEDs are on the right. Then slide the drive carrier into the
drive slot until the locking mechanism latches.
4.
Gently push the lever until it meets the latch on the left side of the drive slot and clicks
into place.
5.
To install additional hard drives, repeat this procedure.
To maintain proper airflow and cooling, a drive carrier (with or without a
hard drive installed) must be installed in every slot of the enclosure.
To remove a hard drive, use the following procedure:
1.
Squeeze the latching mechanism on the front of the drive carrier that you wish to
remove.
2.
Pull the drive carrier out of the DSN-4000 series enclosure.
Be careful to remove the correct drive carrier, since removing the wrong
drive may cause some volumes to fail or become reduced.
