10.1.2. FlashCopy and VolumeCopy support statements
The use of DS4000 or DS5000 FlashCopy and VolumeCopy with IBM i as a client of VIOS is
supported as outlined below.
Please note
that to implement and use this solution,
multiple
manual steps on the DS4000 or DS5000 storage subsystem, in VIOS and in IBM i are
required
. Currently, no toolkit exists that automates this solution and it is not part of IBM
PowerHA for IBM i. The components of the solution – DS4000 or DS5000
FlashCopy/VolumeCopy, VIOS and IBM i – must be managed separately and require the
corresponding skill set. Note also that support for this solution will be provided by multiple IBM
support organizations and not solely by the IBM i Support Center.
Support statements:
•
DS4000 or DS5000 FlashCopy and VolumeCopy are supported by IBM as a client of
VIOS on both IBM Power servers and IBM Power blades
•
Full-system FlashCopy and VolumeCopy when the production IBM i logical partition
(LPAR) is powered off are supported
•
Full-system FlashCopy and VolumeCopy when the production IBM i LPAR is in restricted
state are supported
•
The DS4000 or DS5000 'disable' and 're-create' functions with full-system FlashCopy and
VolumeCopy when the production IBM i LPAR is powered off or is in restricted state are
supported
•
Full-system FlashCopy and VolumeCopy of the production IBM i logical partition (LPAR)
after only using the IBM i 6.1 memory flush to disk (quiesce) function are
not supported
•
Full-system FlashCopy and VolumeCopy when the production IBM i LPAR is running are
not supported
•
FlashCopy and VolumeCopy of Independent Auxiliary Storage Pools (IASPs) are
not
supported
•
Having the production and backup IBM i LPAR under the same VIOS is
not supported
