I like to thank all managers who replied. I didnt expect so much
help. Everything worked ok and the new hard disk is working without
any problems. With all the responses, I could pick out those which I
could understand best.
The problem was:
my DEC-Alpha 500 au is running out of disk space. So I have bought
a new SCSI hard disk which is similar to the first SCSI disk. The new
disk space is 9 GB (the old one has 4.3 GB). The operating system is
Digital-Unix 4.0D.
questions :
1. Do I have to do a special backup of all the system files in case
something goes wrong?
2. Can I install the new hard disk in the tower, connect it like it
is showed in the manual and then just reboot the system?
3. Does the system recognize the new hard disk when it reboots?
4. Do I have to recompile the kernel and if yes, how?
The new hard disk will only have data from calculations on it. So
there shouldnt be any root directory or something like that.
I think it should be possible to mount the new partition with e.g.
/data and then just save all the data on it.
5. My old hard disk is mounted on /dev/rz16. Do I have to choose the
file /dev/... for the new hard disk, or does the system choose this
file itself?
answers:
1. It is not necessary, but a backup is always a very good idea.
2. Yes. Only the SCSI ID should be set to a different number than the
number of the old disk .And it should not be terminated.
3. Yes, the system will recognize the new device. After rebooting,
"show device" will show, if it worked ok.
4. No, this is not necessary. If yes, the command "doconfig" should
be used
5.The system chooses the file itself. If not, you should use
"makedev". After that, the disk has to be labelled with
"disklabel -rw /dev/rrz??c /dev/rrz??c", where ?? is the device
file number.
Then you should type in:
newfs /dev/rz??c
mkdir /datadisk
mount /dev/rz??c /datadisk
The last step is to write the mount command to the /etc/fstab file
with " /dev/rz??c /datadisk ufs ro 0 0"
Then everything should work ok.
