Mainframe Enablers TimeFinder SnapVX and zDP 8.5 Product Guide

zDP supports secure snapsets. Secure snapsets are created with the Secure snaps feature of SnapVX.

zDP supports snapsets initially created as secure and also lets you make an existing snapset secure.

zDP support of secure snapsets requires PowerMaxOS 5978 or HYPERMAX OS 5977.1028 and later. If all systems in a VDG are not running PowerMaxOS 5978 or HYPERMAX OS 5977.1028 or later, a warning message is issued and the Secure setting is ignored.

To create secure snapsets, use the CYCLE_TIME[,SECURE] or SAVED_SNAPSETS[,SECURE] options of the DEFINE VDG and MODIFY VDG OPTIONS commands. Follow the guidelines for setting the snapset limit with secure snapsets.

To convert an existing snapset to secure, issue the SECURE VDG command. To reset the secure attribute, specify SECURE,NO for the CYCLE_TIME or the SAVED_SNAPSETS parameter on the MODIFY VDG OPTIONS command.

Secure snapsets are indicated with “-I” in the QUERY VDG SNAPSET command output.

• A secure snapset is created with “-I” in its snapset ID and state, for example:

  EIP0039I VDG1...........170971440I00001 ACT-I 05/07/2017 14:40:15

• An existing snapset is not renamed upon conversion to secure; however, it is displayed with “-I” due to the secure attribute:

  EIP0039I VDG1...........171311014C00002 ACT-I 05/11/2017 10:14:39

To view the current secure settings for a VDG, issue the QUERY VDG STATUS command and look for the SECURE values:

...
EIP0021I     Cycle_Time(5,0,SECURE,1),Cycle_Overflow(IMMED),Consistent(YES),Timeout(15,CONT) 
...
...
EIP0021I     Max_Snapsets(256),Saved_Snapsets(1,2,SECURE),
Persistent_Copy_Limit(32)
...
