the drives are powered up after the storage subsystem. For instructions on
powering up the storage subsystem, see the storage subsystem
documentation.
c. Turn on the power to the DS4000 storage subsystem; then restart or turn
on the power to the host.
10. Turn on the power to each device, based on the power-on sequence in step 9
on page 80. To turn on power to the DS4000 storage subsystem and the
EXP100s, turn on the power-supply switches on the back of the storage
subsystem. You must turn on both power-supply switches to take advantage of
the redundant power supplies.
11. Check the green Drive activity LEDs and the amber Drive fault LEDs above the
new drive CRUs.
Make sure that the Drive activity LEDs are on and the Drive fault LEDs are off.
Note: The Drive fault LEDs might flash intermittently while the drives spin up.
v If the Drive activity LED is off, the drive CRU might not be installed correctly.
Remove the drive CRU, wait at least 70 seconds, and then reinstall it.
v
If the Drive fault LED stays on or the Drive activity LED stays off, the new
drive might be faulty. See the DS4000 Storage Manager software for
problem determination.
12. Use the DS4000 Storage Manager software to configure the new drives. See
the DS4000 Storage Manager software online Help for detailed instructions.
13. Restore the data from backup to all the drives.
Replacing the drives one at a time
Use this procedure to replace all the drives one at a time. You cannot use this
procedure on RAID 0 logical drives (use the procedure in “Replacing all drives at
the same time” on page 79).
Note: If your storage subsystem has hot spares assigned, you might want to
unassign the hot spares while you perform this procedure. If you do not,
reconstruction might start on the hot spare before you insert the new drive.
The data on the new drive is still rebuilt, but the process takes longer for
each drive. Remember to reassign the hot spares when you are finished with
this procedure.
Attention:
v After you remove a drive CRU, wait at least 70 seconds before replacing or
reseating the drive CRU to allow the drive to properly spin down. Failure to do so
may cause undesired events.
v Before you insert the new SATA drive option or drive CRU/FRU into the DS4000
configuration, you must ensure that the installed DS4000 controller and EXP100
ESM have the minimum controller and ESM firmware versions that are required
for the new SATA drive. Always check the documentation that is included with the
new drive to find out the minimum controller and ESM firmware versions, or any
prerequisite tasks, for DS4000 controller and EXP100 ESM.
To replace the drives one at a time, perform the following steps:
1. Read the following information:
v “Replacing multiple drives” on page 78, particularly the paragraphs that
discuss the differences between the two possible upgrade procedures
v Your software documentation regarding drive upgrades and installation
v
The documentation that comes with the new drives
