Is this a split bus 2104? If so, you might need to attach SCSI to the
other connection on the 2104.

Hmm, in looking at the options available on the menus I think he may be
right. I never actually *added* drives to it (yet), but I did initially
set it up... I guess I was just assuming that being able to add drives
to an array would be something you would "normally" do and would be
easy.
I looked through IBM's site, which was, as usual, just short of
useless... the docs on the DU3 were unavailable (yay internal server
errors!), and the online docs for the 7026 didn't really look like they
mentioned the DU3. The support search didn't seem to turn up anything
useful either. Paper docs for the DU3 didn't so much as mention
software...
It *appears* that what you should do is add the drive as a hot spare,
back up the original array, and then reconstruct the array. I'm really
hoping I'm wrong on this and that someone can point us to some docs that
show how to add a disk to that critter...

Jim,
I'd really LIKE to be wrong!
If you're just looking for the additional space in a couple of vg's, you
should be able to make the disks pdisks and add them to the volume
groups. But that would mean you would have your existing RAID 5 array,
and a non-redundant disk in the vg. Gets you the space, but not the
redundancy.
My experiences with IBM array controllers is primarily with SSA, so I
welcome any responces to this thread that point out errors in my
understanding.
And yes, that's a good thing to be scared of!

Harold,
I sure HOPE you are wrong, but I am having trouble. I can add the disks
as hot spares, change them to spares, but I don't seem to be able to add
them to the array. All I want to do is add one disk each to 2 existing
volume groups. I'm not really supposed to be even supporting this box,
and I certainly don't feel like blowing the array away and recreating
it. Kind of scares the hell out of me... Thanks Jim

Jim,
I could be wrong (it happens a lot!) but I do not think you are going to
do what it sounds like you want to do. I've never been able to add
disks to an existing array. I can create spare drives, or create an
additional array (if the particular array controller supports multiple
arrays) or use the drives as non-array drives, but not add to an
existing array.
It seems logical you should be able to add the drives to expand an
array, but the only docs I found said to backup to tape, destroy the
array, rebuild with new drives included, restore data. Wish I had a
better way.
If I am wrong, I'd be happy to be enlightened.
Harold

Robert,
Here's what I get following your hint...It looks like that's the trick,
because it does see them. I suppose I will CAUTIOUSLY add them to the
existing array. They then show up in the ADD HOT SPARE option. I am
assuming once I do that I can assign them to volume groups, etc. in the
usual way?
Thanks!
Jim

I have this same hardware setup - try looking in smitty devices -> Disk
Array -> IBM PCI SCSI Disk Array -> PCI SCSI Disk Array Manager, you
might find some useful stuff in there.
Once you plug in the drives I *think* the green light should light up on
them (may not till you configure them), and with the Disk Array menus
you should be able to add them to your current array (or create a new
one, though I'm not sure if that adapter will support more than one
array...). I remember scratching my head over this till I found those
menus...
HTH...

Can you hear the drives spinning up or do you see a green LED on these
drives?
You may have to provide AIX with additional drivers. Doing a cfgmgr -v
may show you AIX is looking for drivers or some other clue.

Yes they are scsi. They are mounted in a 2104-DU3 expandable storage
unit. (I'm just reading the specs here, I'm never dealt with this unit
before)
Thanks,

John,
I have never dealt with this machine before, (only worked with F50's),
but these go into a 2104 drive module. They don't show up at all.
There were 8 disks in it already, and these are the 9th and 10th.
Thanks
Jim

You don't say whether they were hotpluggable disks or not, so we'll
assume they were. after you inserted the drives, did you get power back
to the drive slots? You might check and see if they show up, but as
defined, not available.

Hello list. I just received two 73gb drives for a 7026-B80. I put
them in place yesterday, and thought they would become available by
running cfgmgr, but they do not appear. So, I scheduled a reboot last
night hoping that would take care of it, but still no luck. In looking
at the Installation instructions it appears that it might need a power
off/ power on. Is there any way around that?
Thanks,
Jim
