b. Install the drives you that you removed previously in the drive drawer,
one disk drive at a time. Wait at least 90 seconds or until each drive is
recognized in the IBM DS Storage Manager Physical View before inserting
the next drive. If you do not wait until the drive is recognized by the IBM
DS Storage Manager, one or more drives will be marked as
failed/bypassed or incompatible. If this occurs, you must remove the
failed/bypassed drive, reinsert it, and wait at least 90 seconds or until it is
recognized by the IBM DS Storage Manager. See “Installing hot-swap hard
disk drives” on page 92 for the steps to install the drives.
Attention: You must add the drives to the same location in the drive
drawer that they were in before the drive drawer was replaced.
c.
Push the drive drawer all the way in until the latch fully engages.
8. Install the bezel on the front of the storage expansion enclosure. See
“Replacing the bezel” on page 106 for the steps to install the bezel.
9.
Remove the anti-static protection.
10. Is the storage expansion enclosure power turned on?
v
No - You are finished with the procedure, and you can turn on the power.
v
Yes - Go to step 11
11. The Service Action Allowed LED on the replaced drive drawer should be
turned off automatically by the controllers. If it is not turned off automatically,
open the script window for the DCS3860 storage system, and run the
following SMcli script command:
set enclosure [enclosureID] drawer [drawerID]
serviceAllowedIndicator=off;
Where:
v [enclosureID]
is the identifier of the storage expansion enclosure that
contains the replaced drive drawer. Drive enclosure ID values are 0 to 99.
v [drawerID]
is the identifier of the replaced drive drawer. Drawer ID values
are 1 to 5.
This command turns off the blue Service Action Allowed LED that is located
on the drive drawer and allows the controller to access the storage expansion
enclosure.
12. Use the IBM DS Storage Manager to verify that the new drive drawer is
operating correctly.
Replacing an enclosure chassis
The replacement chassis package includes a RID tag and a power supply module.
You can either ship this power supply module or your existing power supply
module back to IBM along with the old enclosure chassis.
Before you begin, ensure that you wear an anti-static wrist strap.
Complete the following steps to replace the enclosure chassis.
1. Schedule downtime for the storage system configuration, and:
a. Stop all applications in the servers, and either unmount or remove the
drive letters of the mapped LUNs from the storage system.
b.
Use the IBM DS Storage Manager to collect support data of the system.
Save this information in a location other than the mapped LUNs from the
storage system.
