Attention:
v Do not replace a drive unless the drive fault LED is on or you are instructed to
do so by a fix procedure.
v If the drive is a member of an array, go to the management GUI and follow the
fix procedures. The fix procedures mitigate loss of data and loss of access to data
and manage the system's use of the drive.
v Do not leave a drive slot empty for extended periods. Do not remove a drive
assembly or a blank filler without having a replacement drive or a blank filler
with which to replace it.
Procedure
To prepare to replace a drive assembly, complete the following steps.
1. Read the safety information in "Preparing to remove and replace parts" on
page 295.
2. Locate the slot that contains the drive assembly that you want to replace.
a. Refer to "Procedure: Identifying which Storwize V7000 Gen2 enclosure or
canister to service" on page 252 to ensure correct identification of the
correct system or enclosure.
b. The drive slots on the front are numbered 1 - 12. For example, the
numbering is from left to right and top to bottom:
1 2 3 4
5 6 7 8
9 10 11 12
c. If the drive in the slot is faulty, the lit, amber fault LED on the drive helps
identify it.
3. To further help identify the drive assembly, go to the management GUI to
Pools > Internal Storage, select the drive to replace, and click Actions >
Identify. Verify that the correct drive fault LED begins to flash.
Attention: Never hot-swap a hard disk drive when its green activity LED is
flashing. Hot-swap a drive only when its amber fault LED is lit (not flashing)
or when the drive activity LED is off.
To remove a drive assembly, complete the following steps.
4. Press the latch on the right end of the tray handle to release it.
5. Pull out the tray handle to the open position (see Figure 94 on page 322).
6. Grasp the handle and pull the drive partially out of the bay.
7. Wait at least 20 seconds before you remove the drive assembly from the
enclosure to enable the drive to spin down. This avoids possible damage to
the drive.
8. Make sure that there is proper identification (such as a label) on the hard disk
drive.
9. Gently slide it completely out of the enclosure.
10. If the drive failed, record that information on its label.
To install a drive assembly, complete the following steps.
11. Touch the static-protective package that contains the drive assembly to any
unpainted surface on the outside of the enclosure.
12. Remove the drive assembly from its package.
13. Make sure that its drive-tray handle is in the open (unlocked) position.
14. Align the drive assembly with the guide rails in the bay (see Figure 95 on
page 322).
