Setting Up The Virtual Volume (V-Vol) (Manual Method) - Hitachi AMS2100 User Manual

Setting up the Virtual Volume (V-VOL) (manual method)

5-4
Hitachi AMS 2000 Family Copy-on-Write SnapShot User Guide
SnapShot creates a volume pair from a primary volume (P-VOL),
which contains the original data, and a SnapShot Image (V-VOL),
which contains the snapshot data. SnapShot uses the V-VOL as the
secondary volume (S-VOL) of the volume pair. Since each P-VOL is
paired with its V-VOL independently, each volume can be maintained
as an independent copy set.
You must set up the V-VOL manually when using the Create Pair
procedure. If you will use the Backup Wizard in the GUI to create an
initial pair, the V-VOL is created and set up automatically during the
pair creation operation. When using the Create Pair procedure, you
must set up the V-VOL manually. However, the prerequisites apply to
both methods.
Prerequisites
• The V-VOL LU must be the same size as the P-VOL.
