(4) Notes for encryption

• A disk array can consist of mix of encrypted hard drives (SED) and unencrypted hard drives
(non-SED).
• A pool cannot consist of mix which includes encrypted hard drives and unencrypted hard
drives. Bind hot spare disks for both encrypted hard drives and unencrypted hard drives.
• When data stored in SED is replicated to non-SED , the data replicated to non-SED HDD will
not be encrypted.
• When creating snapshot of data in SED, create SRA (Snapshot Reserved Area) in SED. If
SRA is created in non-SED, SV (Snapshot Volume) will not be encrypted.
• Do not apply SSD secondary cache for the logical disk by SED. The data in SSD secondary
cache is not be encrypted.
• A pool cannot be bound Immediately after unbinding a pool with SED HDDs. Wait a few
minutes, and then bind a pool. If it fails, wait another few minutes, then bind a pool. A logical
disk can be bound immediately after unbinding a logical disk.
