4 Using Snapshot XP
This chapter describes procedures for using Snapshot XP.
The first section describes the flow of Snapshot XP processes. The next section describes how the status of
a Snapshot XP pair changes while using Snapshot XP. The other sections provide information needed to
create pools and switch off the array’s power supply after you start using Snapshot XP.
Procedure for using Snapshot XP processes
Figure 3 Procedure for using Snapshot XP
To create pools and V-VOLs, use Command View XP or XP Remote Web Console. To create Snapshot XP
pairs and perform subsequent operations, use RAID Manager XP. You can also use Command View XP or
XP Remote Web Console to delete pairs. For more information, see ” Snapshot XP operations ” on
page 37.
NOTE:
•
Before creating a pool, you must create the virtual volume management area in shared memory.
Virtual volume management areas are automatically created when you install additional shared
memory. For more information about installing additional shared memory, contact your HP account
support representative.
• If you already created pools or Snapshot XP pairs for testing purposes before you actually start using
Snapshot XP for production purposes, HP recommends initializing the V-VOL management area
beforehand. For more information, see ” Initializing V-VOL management areas or pool management
blocks ” on page 48.
You do not always need to delete Snapshot XP pairs after storing snapshot data in the pool. However,
since one P-VOL can be paired with up to 64 S-VOLs, you must delete the snapshot data or unnecessary
pairs. When deleting a Snapshot XP pair, the pair’s snapshot data is also deleted from the pool.
