Re: PowerHA Full System Flashcopy

Holger, Gerald,

What IBM was probably wanting to explain was that the FSFC (if it is part
of the Toolkit from LabServices like I think it is) does the following
without human intervention:
1. Create a Flashcopy of the LPAR
2. Create an LPAR with a set of defined resources (for example, the cards
or vFCs required for tape access)
3. IPL that LPAR and make the backup
4. Shutdown the LPAR and delete everything

If they aren't talking about the Toolkit (which, IIRC becomes expensive if
you don't use PowerHA since it requires it) then I am not sure what product
they refer to, but the idea remains the same.
You can also do it manually if you want. Just have an LPAR created and
mapped to the flashcopy target, just make sure to halt the flashcopy before
IPL, backup and finally shutdown the LPAR.

SAN Storage makes your life a lot easier.

sounds some weird.

The „system ASP“ can be on an external SAN since years (if not decades)
- depending on the SAN.
Also a FlashCopy of the System ASP can be done IIRC even with Power5
systems connected to a V7000;
it will get complicated when you have additional iASP.

Betreff: PowerHA Full System Flashcopy

I got a email from IBM about a utility to perform a Flash copy to a new
LPAR, then you can do a restricted save.

a statement in the note says: The Full System Copy Services Manager (FSFC)
for IBM i is unique as it does not require an IASP, but instead Flashes

the

system ASP.

System ASP, vs. IASP. So on current models, the System ASP can exist

on

External Disk?
I think of "System ASP" as "disks formatted and owned by a IBM i server",
and a IASP as "a SAN that presents disk to IBM i". But we can now have
the IBMi point to a san and say "put my System ASP here"?
