Prerequisites For Creating Bc Z Pairs; Creating Bc Z Pairs - HP XP7 User Manual

Prerequisites for creating BC Z pairs

The following are prerequisites for creating BC Z pairs:
The P-VOL and S-VOL are unpaired.
If the P-VOL is already paired with other S-VOLs ("DUPLEX" status), you have determined that
the status of existing S-VOLs is the status that is required to create the new pair.
For more information about S-VOL status, see
(page 68).
If you are concerned with host I/O performance, make sure that the I/O load is light.
For more information about checking I/O performance-related information, see the HP XP7
Remote Web Console User Guide.

Creating BC Z pairs

Creating a BC Z pair copies the P-VOL to the S-VOL.
If your HP XP7 has encryption DKAs, you can copy an encrypted volume to an unencrypted volume.
There is no guard logic to enforce copying encrypted P-VOLs to only encrypted S-VOLs. Unless
there is a specific reason for the data to become unencrypted, make sure you maintain the encryption
by using only encrypted S-VOLs.
