Unblocking LDEVs at the parity-group level
Unblock LDEVs at the parity-group level to protect the data after you format an LDEV at the
parity-group level. Unblocked LDEVs in the parity group have a status of “Unblocked”.
1.
From the RWC main window, click Explorer > Storage System > volume (resource).
2. On the LDEVs tab, complete the following and then click Unblock LDEVs:
•
For Parity Group, select the parity group to which the LDEV is associated.
•
For Logical Device, select the LDEV you want to unblock.
3. In the confirmation message that appears, click Apply.
The LDEV is unblocked.
Moving unencrypted data to an encrypted environment workflow
Migrate existing data to the new LDEVs in the encrypted parity group.
If you are migrating existing unencrypted data to an environment with encryption, the process
includes the following additional steps:
1. Move the unencrypted data from the P9500 storage system to another storage system.
For more information about moving unencrypted data, contact HP Technical Support.
2. Create a new parity group.
For more information about creating parity groups, see HP XP P9000 Provisioning for
Mainframe Systems User Guide.
3. Enable data encryption on the parity group.
For more information about enabling data encryption on parity groups, see “Enabling data
encryption at the parity-group level” (page 19) .
4. Format the LDEVs in the encrypted parity group.
For more information about formatting LDEVs, see “LDEV encryption formatting at the
parity-group level” (page 21) .
5. Migrate the existing data to the new LDEVs in the encrypted parity group.
For more information about migration practices with encryption, see “Migration practices with
encryption” (page 8) .
For more information about data migration services, contact HP Technical Support.
Data encryption license key restoration workflow
Restore a data encryption license key from the primary or secondary backup copy when all the
LDEVs belonging to an encrypted parity group are blocked or if an existing data encryption license
key becomes unavailable or you cannot use it. For example, a system failure occurred.
The system automatically restores data encryption license keys from the primary backup. You must
have Security Administrator (View & Modify) role to restore the data encryption license key from
a secondary backup data encryption license key.
Use the following process to restore a data encryption license key:
