Only running DSS. We are too far down the rabbit hole to ever switch to
ESS now.
Mixing DSS and ESS in the same cluster is not a supported configuration.
I know, it means you can never ever migrate your storage from DSS to ESS
without a full backup and restore. Who with any significant amount of
storage is going to want to do that? The logic behind this escapes me,
or perhaps in that scenario IBM might relax the rules for the migration
period.
You really need to talk with Lenovo as is your vendor. The fact that in
your region your support is being given by an IBMer or not is not a
relevant point. High enough in the chain always will end at IBM on any
region as GNR is IBM tech for 17 years (yes 17) so if weird enough even
on regions where Lenovo might do even third level it might end on
development and/or research. But that is a Lenovo/IBM agreement not you
and IBM.
So please get the support statement from Lenovo about this and pls share
it if you want/can so we all learn their position.
Will attempt that, though I do think it should be a supported config out
the box :-)
