Re: Oracle on an HP AutoRAID Model 12H, HP-UX 11i
BTW, do you have latest AutoRAID firmware (HP62)?

Re: Oracle on an HP AutoRAID Model 12H, HP-UX 11i
LUN already, is this enough for the autoRAID to start with
0/1 processing or do I need to
reformat the drives. I'm confused by the Raid 0/1 capacity of 4MB in the arraydsp -a info, when I've
defined 50GB of unallocated
space and the manual states
it will use that for raid 0/1
processing.

Force Unit Access Response = 2

Why read cache is disabled? Why rebuild priority is high (will slow down normal host activities in case of rebuild)?
I found doc stating that all large transfers always go to RAID 5 directly and then if needed will migrate to RAID 0/1. In addition, in case of rebuild data will go do RAID 5 also.
So there are only 2 possibilities: either you had rebuild recently or you did large data transfer

Re: Oracle on an HP AutoRAID Model 12H, HP-UX 11i
about what default settings
are and what it would mean
to change the settings, or how to do it. The book is from Feb 1999. That combined with the
fact that I'm fairly new at this and have never worked with an autoraid means I need
help. I'm trying to set this
up for a whole new oracle db
system, current db size is <10GB but we need some room to
grow. DBA thought maybe 30GB
would cover growth, I decided
to give him 45GB which leaves
the 50GB unallocated. We haven't even loaded the DB yet
which is why I'm confused about the raid 0/1 capacity=
numbers. Having deleted and
recreated the lun it should
show 50gb available for raid 0/1 or maybe that's not what
capacity means in this instance.

PS. Do you think not assigning points to answers will encourage people to help you in your problems?
