1.
While the destination storage subsystem is turned on, insert the migrating
drives into an empty drive bay one at a time. Wait (up to 5 minutes) until the
inserted drive is fully spun up and displayed in the Storage Subsystem
Management window before you insert the next drive. Arrays appear in
Contingent state (with an arrow icon) until all of the drives in the array are
inserted. The array appears in Exported - ready to import state.
2.
If the migrated drives are FDE drives and were configured as part of secured
array, use the saved security key to unlock the drives. Without this security key,
the controllers cannot unlock the drives to retrieve the array configuration data
and data on the drives. Therefore, you cannot import any array/logical drive
configuration from the drives or access data in the drives.
3.
Complete the following steps to migrate all of the drives, import the array:
a.
Right-click on the name of the array that you want to import in the Storage
Subsystem Management window.
b.
Select Advanced -> Import from the pull-down menu.
c.
In the confirmation window, click OK.
d.
Click Import.
e.
In the Import Array window, type
yes
and click OK.
After a successful import, the message
Array was imported successfully
is
displayed in the dialog box.
f.
Click Close.
4.
If any of the following conditions occur, contact IBM support for assistance:
v
The Empty Drive Bay icon (
) is displayed for the drive bay into which
you inserted the migrating drive.
v
The Failed Unconfigured Drive icon (
) or the Failed Configured Drive
icon (
) is displayed for the drive bay into which you inserted the
migrating drive.
v
Array configuration data on the drives that you added is incomplete.
v
You cannot import the array.
Attention:
Do not initialize a hard disk drive that you want to keep (by right-clicking its
icon and selecting Initialize from the menu) if it contains configuration or user
data. Initializing any drives in a defined array causes all hard disk drives that
are known to make up that array to return to the Unconfigured Capacity
storage pool, deleting their array definitions from the DS4000 storage
subsystem configuration. The user data on such drives is lost.
When the arrays are online, they are ready to for you to configure and map to
host servers. You might also then re-create FlashCopy images of the logical
drives.
5.
Use the DS Storage Manager program to view the storage partitioning
definitions and make any necessary corrections.
Note:
The source storage subsystem might indicate that the logical drives are
missing. To remove the missing logical drives, right-click each entry and select
Delete
from the menu.
