Raid1+0 Configuration HP Smart Array P400

[MoXon]

Hello,

we have a HP ProLiant DL380 G5 with 8x146GB drives. Currently I have 1x146GB dics for the System with Raid0. Now, I would like to setup a mirror with 2x 146GB with Raid1.

The question...can i add the disc without losing data and change the Raid to 1?
And is mirrored all Systemdata in the new disc automatically?

thanks for anwser...sry for bad english ;)

Yes you can migrate from raid 0 to raid 1. Just boot to smartstart and use the array configuration utility from there and make the changes.

do you have the BBWC option installed or not?

I'm not sure we used the Smart Array P400.
Can I everywhere see, if BBWC install?

[Ryan Goff]

BBWC is only required for ADG (Raid 6) so you won't need to worry about it for Mirroring.

[Mauro Rusignuolo]

no, excuse me:
BBWC it's REQUIRED for the on-line-level-raid-migration.

from the specifications:

<<...
Addition of the battery backed cache upgrade enables BBWC, RAID 6 with ADG, array expansion, logical drive extension, RAID migration, and stripe size migration.
...>>

That is correct jackal...there must be a BBWC installed, at least 256 MB to perform Raid Migration, expansion and extensions...

take a look if you have SA E200 or P400

also according to this

http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&objectID=c00712808&jumpid=reg_R1002_USEN

no matter which model "entry - base -performance"

the smart array should have BBWC by default, it can be 256(P400) or 64 (E200)

you can do yuor migration

Hello,

that's right. The "old" Smart Array (before E- and P-Series)activates only the write cache after an upgrade with a BBWC, online array expansion, raid migration etc. was enabled by default.

The new E- and P-Series controller activate this features only after the installation of a BBWC. In addition to that, RAID ADG is then available on P400/600/800, and RAID 5 on E200/500.

Just take a look in the quickspecs.

For me: I don't sell any ProLiant without a BBWC, regardless of which Smart Array Controller is build in. ;)

Best regards,
Patrick
