I have an alphastation 600 with DU 4.0D and just added a Seagate 18.2 GB ultra-SCSI external
disk drive -- my first such experience. I installed and partitioned the disk and can use it
now, but the installation was less than smooth as it wasn't clear to me -- and still isn't -- as
to where the Dynamic Device Recognition leaves off and where I get involved. The documentation
isn't clear on this issue. This is what I did:
1. After I installed the drive and powered up ( external drive was turned on first), the disk
wasn't initially recognized by the system. It should have been, right? I ended up rebooting
using genvnumix, and when I did the disk was recognized and the MAKEDEV had been done. The
DEC System docs say that a reboot isn't necessary with DDR. What am I missing?
2. Since I rebooted with genvmunix, I thought I might have to edit the configuration file DELTA
to include the new device. I ran sizer and found the entry
#UNSUPPORTED msb0 at eisa0 slot 4 in /tmp/DELTA
I changed this to: device disk msb0 at eisa0 slot 4 (in DELTA)
and tried to rebuild the kernel with doconfig -c DELTA. This didn't get far so I took out
the new device entry and tried again, this time successfully. Apparently the
configuration file doesn't need the new entry since the device was already recognized.
3. I went on to label and partition the drive with the widget, then made a file system with
newfs and mounted it.
Although the disk is working, my experience has left me wondering how a "proper" installation
should go. I'd appreciate any advice on how to procede with my next disk installation, and
comments on exactly what DDR does.
TIA
