Key rotation for encrypted storage media using a mirrored volume revive operation

1. A method of performing key rotation in a computing environment having a host coupled to a first and a second storage media, wherein the first and second storage media are in a mirrored volume configuration and wherein the first storage media is configured as a first mirror storage media and the second storage media is configured as a primary storage media, the method comprising:

utilizing a processor to execute instructions stored on a non-transitory readable media for:

initializing a target storage media with a new key;

coupling the target storage media to the host and configuring the target storage media as a second mirror storage media;

performing a mirror revive operation from the first storage media to the target storage media to perform key rotation, wherein the second storage media provides service requests to the host during the mirror revive, and wherein the mirror revive operation is optimized using one or more of a data block map optimization or a high water mark optimization;

configuring the second storage media as a new primary storage media and configuring the target storage media as a new mirror storage media to comprise the mirrored volume; and

configuring the first storage media as a new spare storage media and uncoupling the first storage media from the host, wherein the new spare storage media includes at least data stored in the first storage media.

2. The method of claim 1 wherein initializing the target storage media with the new key comprises accessing a key manager to obtain the new key.

3. Non-transitory readable media having computer executable program segments stored thereon, the computer executable program segments comprising:

a mirrored volume I/O manager for maintaining a mirrored volume on a plurality of storage media; and

a key rotation initiator module for:

initializing a target storage media of the plurality of storage media with a new key;

coupling the target storage media to a host and configuring the target storage as a second mirror storage media;

performing a mirror revive operation from a first storage media of the plurality of storage media to the target storage media to perform key rotation, wherein the first storage media is in a mirrored volume with a second storage media of the plurality of storage media and wherein the second storage media provides service requests to the host during the mirror revive, and wherein the mirror revive operation is optimized using one or more of a data block map optimization or a high water mark optimization;

configuring the second storage media as a new primary storage media and configuring the target storage media as a new mirror storage media to comprise the mirrored volume; and

configuring the first storage media as a new spare storage media and uncoupling the first storage media from the host, wherein the new spare storage media includes at least data stored in the first storage media.

4. The non-transitory readable media of claim 3 wherein the first and target storage media comprise the mirrored volume before the mirror revive operation.

5. A computing environment comprising:

a plurality storage media that includes a first storage media configured as a first mirror storage media and a second storage media configured as a primary storage media in a mirrored volume;

a storage area network coupled to storage media of the plurality of storage media;

a host coupled to the storage area network, the host including memory which includes:

a mirrored volume I/O manager that maintains a mirrored volume using storage media of the plurality of storage media; and

a key rotation initiator module, wherein the key rotation initiator module initializes a target storage media of the plurality of storage media with a new key, couples the target storage media to the host and configures the target storage media as a second mirror storage media in the mirrored volume, performs a mirror revive operation from the first storage media to the target storage media to perform key rotation while the second storage media provides service requests to the host during the mirror revive, wherein the mirror revive operation is optimized using one or more of a data block map optimization or a high water mark optimization, configures the second storage media as a new primary storage media and configures the target storage media as a new mirror storage media to comprise the mirrored volume and configures the first storage media as a new spare storage media and uncouples the first storage media from the host, wherein the new spare storage media includes at least data stored in the first storage media.

6. The computing environment of claim 5 wherein the first and target storage media comprise the mirrored volume before the mirror revive operation.

7. The computing environment of claim 5 wherein the memory of the host further includes a key policy management module for implementing a key rotation policy.

8. The computing environment of claim 5 and further comprising:

a key manager, the key manager including:

a key manager server module for providing keys used to access the first and target storage media; and

a key table that stores and associates key names with keys.
