Re: P7 740 E6C EXP24S mode 1, disk upgrade options

Maybe i'll remember to not read redbooks while feverish. 822 does not run
IBM i so of course it's not mentioned, but i went to the 814/824 redbook
and the following appears:
To support Easy Tier, make sure that the server is running at least the
following minimum
levels:
VIOS 2.2.3.3 with interim fix IV56366 or later
AIX 7.1 TL3 SP3 or later
AIX 6.1 TL9 SP3 or later
RHEL 6.5 or later
SLES 11 SP3 or later
IBM i supports Easy Tier only through VIOS.

So it's confirmed. EasyTier for IBM i only thru VIOS and only on select
controllers for Power8 systems.
