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. Also note 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 and DS5000 FlashCopy and VolumeCopy are supported by IBM i 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 and 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.
