Hi Gurus,
We bought a IBM Ultrastar 18ES 18.1Gb external disk and would like to
install it in a DEC AXP 3000 600M box (the seller Western Scientific claims
it fits the box), running DU 3.2. Attached to the scsi cpu connector is
a column with six 2Gb disks and a DAT tape unit, occupying the scsi
numbers 8, 9,..., 14. There are also two internal disks with numbers 2
and 3; CD-ROM unit is number 4:
scsi0 at tcds0 slot 0
rz2 at scsi0 bus 0 target 2 lun 0 (DEC _ RZ28B (C) DEC 0003)
rz3 at scsi0 bus 0 target 3 lun 0 (DEC _ RZ28B (C) DEC 0003)
rz4 at scsi0 bus 0 target 4 lun 0 (DEC _ RRD43 (C) DEC 0064)
scsi1 at tcds0 slot 1
rz8 at scsi1 bus 1 target 0 lun 0 (DEC _ RZ28 (C) DEC D41C)
rz9 at scsi1 bus 1 target 1 lun 0 (DEC _ RZ28 (C) DEC D41C)
rz10 at scsi1 bus 1 target 2 lun 0 _(DEC RZ28 (C) DEC D41C)
rz11 at scsi1 bus 1 target 3 lun 0 _(DEC RZ28 (C) DEC D41C)
rz12 at scsi1 bus 1 target 4 lun 0 _(DEC RZ28 (C) DEC D41C)
rz13 at scsi1 bus 1 target 5 lun 0 _(DEC RZ28B (C) DEC 0003)
tz14 at scsi1 bus 1 target 6 lun 0 _(DEC TLZ06 (C)DEC 0491)
We have connected the disk to the empty connector in the column with a 68
pin cable. We tried to identify the disk as scsi number 15 and followed the
steps:
1) cd /dev
./MAKEDEV rz15
2) Added the line to /etc/disktab
rz30:\
:ty=dynamic_geometry:dt=SCSI:ns#-1:nt#-1:nc#-1:
3) By giving the command
disklabel -rw /dev/rrz15c rz30
we get a error message:
disklabel: /dev/rrz15c: No such device or address
Then we tried the scsi number 7 but to no avail. We have tried those
steps both using and not using a terminator in the external disk box.
When turning on the station, one of the disk leds blinks; so it is
not completely unseen. However it is not detected in the LSM prompt with
show device or during boot. Any hints on what is wrong and how to install
such a ultra scsi disk? Maybe the /etc/disktab entry is not appropriate.
Suggestions?
TIA,
