Re: HSG80 acs 7.8f

It's not really clear what you are trying to ask and what you mean by "addition".

There is a controller limit of 30 storage sets of type (RAID-1, RAID-5). If you already have 24 RAID-1 and 6 RAID-5, then you can't create any more RAID-1 or RAID-5 sets.

But perhaps you are asking for mirroring an existing mirror or striped mirror, something like this:

> add mirrorset m1 disk10000 disk20000
> add mirrorset m2 disk30000 disk40000
> add mirrorset m3 m1 m2

or

> add mirrorset m1 disk10000 disk20000
> add mirrorset m2 disk30000 disk40000
> add stripeset s1 m1 m2
> add mirrorset m3 disk10100 disk20100
> add mirrorset m4 disk30100 disk40100
> add stripeset s2 m3 m4

Such configurations are not possible with the HSG firmware - you can only stripe existing mirrors - other layering of RAID-0, RAID-1 or RAID-5 is not possible.

Re: HSG80 acs 7.8f

Hi Uwe Zessin,
many thanks,
my question is :
I have configured 24 raid1,each is file system,
then I add tow raid+1 using three mirrors,
i.e I create three raid1 then stripe them,
I want to create new raid0+1 using the same manner,
note:the total number of raid1 is 30
(24 (raid1) + 6 (raid0=1) )
please advise,

Re: HSG80 acs 7.8f

Sorry, I still don't understand what you are trying to ask. A stripeset (RAID-0) does not count against the 30(RAID-1,RAID-5) limit. If you currently have 24 mirrorsets and no raidsets (RAID-5), then you can go ahead create 6 more mirrorsets and 2 stripesets, each spanning 3 mirrorsets.

Re: HSG80 acs 7.8f

Hi,

you are talking about the same thing I guess.
Just try the second example of Uwe.

Uwe,
I haven't thought about mirrored mirror sets. Is that for paranoids?

greetings,

Michael
