If the migrated drives from the storage subsystem operate in external license
key management mode, ensure that the new storage subsystem also operates
in external license key management mode and uses the same external key
server.

Preparing to export and import drives
Complete the following steps on the source storage subsystem to prepare to export
drives:
1.
Save the storage subsystem configuration so that a copy of the array
configuration is available, if the export fails.
2.
Stop all I/O and unmount or disconnect the file system.
3.
Back up the array data.
4.
Use the Locate Array function in the Storage Subsystem Manager window to
identify the physical disks that are associated with the array. Then, label each
drive with source and target storage subsystem names, array name, and total
number of drives in the array. After the drives are exported or offline, you
might not be able to use the array locate function to locate the drives that are
part of an array, depending on the version of installed controller firmware.
5.
Ensure that you have enough blank drive canisters or new drives to cover the
drive bays from which the drives are removed to maintain airflow in the
storage enclosure.
6.
If the source storage subsystem contains secured full data encryption (FDE)
arrays, save a copy of the security key in the target storage subsystem.
Verify the following on the target (destination) storage subsystem to prepare to
export drives:
v
You have enough drive bays for the drives.
v
The storage subsystem supports the drives. You cannot exceed the maximum
number of drives that the storage subsystem supports.
v
The storage subsystem supports the RAID level that you are importing. You
cannot exceed the maximum number of logical drives that the storage subsystem
supports.
v
The target storage subsystem supports RAID level 6, if you are importing RAID
level 6.
v
The controllers in the storage subsystem have the latest version of controller
firmware.
v
The latest DS Storage Manager software is installed.
v
You have purchased and enabled any premium feature keys.
v
If the source storage subsystem operates in external key management mode, the
target storage subsystem also operates in external key management mode and is
managed by the same external key manager. That way, you do not have to
supply the security key to unlock the secured FDE drives when importing them.
Otherwise, save the security key in the source storage subsystem.
