Hi all,

Connected to my OpenVMS 8.4 I64 I have both
1) MSA1000 with one MSA30
2) MSA1500 with two MSA20's
This system is working fine and the disks are seen on my OpenVMS system.

Now I connected an extra MSA30 to the second SCSI connection on my
MSA1000. When I look into the MSA1000 I do not see the new box and thus
cannot configure iunits and luns.

The same happened when I added a third MSA20 to the MSA1500 (I had to
insert another SCSI device into the MSA1500). Also here only the "old"
boxes are seen in the MSA1500.

Can anyone give me a hint on why I do not see the "new" boxes?

regards

MSA30 needs one SCSI-controller in the MSA1500.

Two MSA20 may share one SCSI-controller, but MSA30 not.

MSA30 needs one SCSI-controller in the MSA1500.
The MSA30 is connected to A MSA1000 on the second SCSI connections. Or
does the MSA1000 does not allow 2 MSA30's connected on this one controller?

The new MSA20 is connected to the new installed second controller of the
MSA1500. No connection of the second SCSI of this card.

There are several different controllers for a MSA1000. I saw pictures
where more one one MSA30 are added to a MSA1000. So it must be possible in
principle. I had only one MSA30 connect to a MSA1000 and this did work
just like in your case.

The new MSA20 is connected to the new installed second controller of
the MSA1500. No connection of the second SCSI of this card.
My MSA1500 configuration was as follows: 2*MSA20 + 1* MSA30 (the one
that worked properly on a MSA1000, too.).
Are you sure that the new controller works properly? Did you try to
check the connection ("show box" command)?

Are you using the newest firmware version (i.e. v7.20) of the msa1500
controllers?

A msa20 has a programmable firmware, too.

Got the MSA20 connected. The trick was to remove all the disks from the
box, fire it up and when everything is started put the disks bac one by
one. Weird, I did not expect this.

Tried the same fore the MSA30, but that did not work.

Replaced the whole MSA30 box by another one. This one is one with 2 SCSI
connections. I got al little further, because now I see disks 8-14.

Is this a problem of the 2 SCSI connections. What would happen if I
replace the SCSI module by one with only one connections? Is that going
to work or are the MSA30's also different internally?
