HP XP P9000 Auto LUN Software - Manual (Page 15)

In this manual, Thin Provisioning indicates both Thin Provisioning and Smart Tiers. Thin Provisioning
Z indicates Thin Provisioning Z and Smart Tiers Z.

Journal Z
When the selected source volume is a P-VOL or an S-VOL of a Continuous Access Synchronous Z
or Continuous Access Journal Z pair consisting of internal volumes and/or Thin Provisioning Z
virtual volumes, there are some target volume candidates that should not be considered. The
following table lists the possible Internal/THP V-VOL - Continuous Access Synchronous Z/Continuous
Access Journal Z pair combinations, and tells which type of volume should not be considered as
a target volume based on the Continuous Access Synchronous Z/Continuous Access Journal Z pair
combination and the selected source volume.

CAUTION:
•
If you do the Continuous Access Synchronous Z operation so that the Continuous Access
Synchronous Z pair status becomes other than Suspended when Auto LUN and Continuous
Access Synchronous Z share a volume, the Auto LUN process stops.
•
If you do the Continuous Access Journal Z operation so that the Continuous Access Journal Z
pair status becomes other than PSUS when Auto LUN and Continuous Access Journal Z share
a volume, the Auto LUN process stops.

When the selected source volume is a P-VOL or an S-VOL of a Continuous Access Synchronous or
Continuous Access Journal pair consisting of internal volumes and/or Thin Provisioning virtual
volumes, there are some target volume candidates that should not be considered. The following
table lists the possible Internal/THP V-VOL - Continuous Access Synchronous/Continuous Access
Journal pair combinations, and tells which type of volume should not be considered as a target
volume based on the Continuous Access Synchronous/Continuous Access Journal pair combination
and the selected source volume.
