SparcStation 10 Hard Drive Spinup Problem

[John P Verel <jverel@optonline.net>]

[This is a repost from the debian-sparc list.  Sorry for any
duplications[

I have three Sparstation 10s, on which I want to install Debian 3.0 for
SPARC.  Each machine has two SCSI hard drives, a Seagate ST 1480 and a
Micropolis 2117.  The Seagate is at target 1, unit 0, the Micropolis at
target 3, unit 0.  Both drives are found by the kernel per dmesg, as sda
and sdb.  However, I get a kernel message saying that sdb does not
respond to spin up.  Likewise, only sda shows up in fdisk; sdb does not.

I've gone through the Debian installation manual and the Sun OpenBoot
Reference materials in some detail, but find nothing to speak to this.
I've started the machines with the cover off and the Micropolis
sounds/feels like it's powered up.  Also, the OpenBoot SCSI tests come
back normal.

Any help will be most appreciated.

Thanks.

John
