Replacing hot-swap hard disk drives
E-DDM problems include any malfunctions that delay, interrupt, or prevent
successful I/O activity between the hosts and the E-DDMs in the storage
expansion enclosure. This includes transmission problems between the host
controllers, the ESMs, and the E-DDMs. This section explains how to replace a
failed E-DDM.
Note: If you want to remove an E-DDM that is not in a failed or bypass state,
always use the DS Storage Manager client program either to place the
E-DDM in a failed state or to place the array that is associated with the
E-DDM (or E-DDMs) in an offline state before you remove it from the
enclosure.
Attention: Failure to replace the E-DDMs in their correct bays might result in loss
of data. If you are replacing an E-DDM that is part of a configured array and
logical drive, ensure that you install the replacement E-DDM in the correct bay.
Check the hardware and software documentation that is provided with your
DS3950 to see if there are restrictions regarding E-DDM configurations.
Before you begin, ensure that you wear an anti-static wrist strap.
Complete the following steps to replace a hot-swap E-DDM:
1. Use the DS Storage Manager client software to print a new storage system
profile.
2.
Determine the location of the E-DDM that you want to remove.
Attention: Never hot-swap an E-DDM FRU when its associated green Activity
LED is flashing. Hot-swap an E-DDM FRU only when its associated amber
Fault LED is lit and not flashing.
3. Put on anti-static protection.
4. Remove the E-DDM by completing the following steps:
a. Release the latch on the E-DDM FRU by pressing on the inside of the
bottom of the tray handle, as shown by the arrow in Figure 35 on page 71.
b.
Pull the tray handle out into the open position.
c. Pull the E-DDM FRU about 1/2 inch out of the bay and wait 70 seconds to
allow it to properly spin down and the storage subsystem controller to
properly recognize that an E-DDM is removed from the configuration.
d. Verify that there is proper identification (such as a label) on the E-DDM
FRU, and then slide it completely out of the storage expansion enclosure.
5. Unpack the new E-DDM. Save all packing material in case you need to return
it.
Attention: The DS3950 and EXP395 E-DDM options and FRUs are not
compatible with DS4000
™
and EXP810 E-DDM.
6.
Install the new E-DDM FRU by completing the following steps:
a. Gently push the E-DDM FRU into the empty bay until the hinge of the tray
handle latches beneath the storage expansion enclosure bezel.
b.
Push the tray handle down into the closed (latched) position.
7. Check the E-DDM LEDs for the following:
