All -

I'm having a very serious problem with my backup system, and I'm looking
for some quick help please.  My system has been working for months and
this just happend last night, my setup is:
   
   SunSparc Station running SunOS  4.1.1 
   anDATAco 5 gigabyte tape backup unit, using sony 8mm tapes.

When I run the dump command, this is what happens ...

% dump 0bsf 32 160000 /dev/nrst1 /dev/sd0a >>& $log

  DUMP: Date of this level 0 dump: Tue Oct 13 14:11:16 1992
  DUMP: Date of last level 0 dump: the epoch
  DUMP: Dumping /dev/rsd0a (/) to /dev/nrst1
  DUMP: mapping (Pass I) [regular files]
  DUMP: mapping (Pass II) [directories]
  DUMP: estimated 17076 blocks (8.34MB) on 0.00 tape(s).
  DUMP: dumping (Pass III) [directories]
  DUMP: dumping (Pass IV) [regular files]
  DUMP: Tape write error 127 feet into tape 1
  DUMP: NEEDS ATTENTION: Do you want to restart?: ("yes" or "no") yes
  DUMP: This tape will rewind.  After it is rewound,
  DUMP: replace the faulty tape with a new one;
  DUMP: this dump volume will be rewritten.
  DUMP: Tape rewinding

At this point the tape drive seems to 'hang'.  when I try to get a
status of the drive the reply is:

   /dev/rst1: no tape loaded or drive offline


Error messages at system console:

   st1:     Error for command 'write', Error Level: 'Fatal'
   Block: 63     File Number: 0
   Sense Key: Media Error
   Vendor (Exabyte 8mm Helical Scan) Unique Error Code: 0x3


AND I can no longer read any old backup tapes.  Does this mean my
tape drive is DEAD??  I hope not... PLEASE help.

thanks,

After upgrading a Sparc 2 to 4.1.3 (from 4.1.1B) and doing the obligatory
fsck, I get from df:

Filesystem            kbytes    used   avail capacity  Mounted on

...

Now how on earth did this thing learn to subtract?

Deleting some small file aill make the "avail" number go negative, but
after a while it will spontaneously go back to zero.  A full fsck from
single user and a reboot doesn't help anything.

Any ideas?  (Please let it not be the 'ol "backup and restore"!)

I'm willing to be that this one has come up before, but I've not

What does the panic message "swtch" mean?  That seems to be the
only thing recorded in the log (or on screen) when the system
went to a boot prompt....  There were perhaps a dozen users online
at the time with the machine, none doing anything computing intensive,
nor disk intensive.  This is a Sparc2, running 4.1.2.

Thanks in advance for pointing me in the right direction (even

Organization: Curtin University of Technology
Date: Thu, 15 Oct 1992 04:07:40 GMT

Hi All,

Can anyone tell me how to set it up so that both the IPs of my SPARC map
to the same name, and vice versa?  I've installed the resolv+ libraries,
and that works fine, and I'm using the named that came with the SPARC
(4.1.2).  My machine has two IPs, one for its SLIP connection to the
outside world, and one for world and one for the ethernet.  This causes
problems since my machine looks like it is the SLIP IP to outside
machines, and like it is the ethernet IP for local connections.

All the DNS code I've seen has code to handle a name having more than
one IP, but I can't seem to figure out how to set up my named.ca file
for this to work (basically, the lookup for my machine's name needs to
give both the IPs, and the reverse lookup for either IP needs to give
the name.  This only has to work on the local machine, since externally,
the name is mapped and reverse mapped to the SLIP IP.

Thanks for any info,
   Peter.

Date: Tue, 13 Oct 1992 20:33:39 GMT

We have recently acquired a SS10-31, and are experiencing difficulty
in connecting it to our existing thinnet network.  Both Sun and our
distributor have drawn blanks on the problem thus far, so I am
soliciting advice from the net.  No doubt, the problem lies in my
ignorance of 10BaseT cabling and devices.

Here's our setup:

       ---------                -----------   
      | SS10-31 | <----------> | Milan     | <========== existing 
       ---------               | converter |              thinnet 
                                -----------               network

The SS10 is connected to a Milan MIL-120A coax to 10BaseT converter
using the Sun TPE cable that is supplied with the workstation 
(part# 180-1529-01 Rev A).  The other side of the converter is
attached to an existing thinnet network with a standard T-connector.

The SS10 is unable to talk to any system on the existing thinnet
network, and vice-versa.

The converter has a set of Collision and Receive lights for both
connections (i.e. both TPE and thinnet).  Traffic on the existing
thinnet network causes the appropriate lights to flicker on the
converter, as one would expect.  We are unable to cause the
corresponding lights for the TPE side of the converter to flicker at
all.  Thus, it appears that no communication is taking place between
the SS10 and the converter.

We have three new converters, and have tried all three, so it seems
unlikely that a defective converter is the problem.

We have run the watch-tpe command from the SS10 PROM.  If the
tpe-link-test? environment variable is set to 'true', the local test
succeeds, and the external test fails (which, according to the error
message, indicates a cable failure, or that the hub link test is
disabled or unsupported on the hub).  If the tpe-link-test?
environment variable is set to 'false', both the local and the
external tests succeed.  In all cases, watch-tpe fails to show any
traffic on the network.

We have also tried a "crossover" TPE cable, with the same results.

It would seem that we are missing something in our effort to connect a
TPE device to thinnet.  Can someone shed some light on what we are
doing wrong?

Thanks.

Hello!

This morning, I discovered that a whole classroom of people running gopher
can take my gopher server off the air!  For a little while.

I'm running gopherd 1.01 from SunOS 4.1's inetd.  If I bash port 70 by
opening (with a little Perl program) a connection to the port and then
closing it again right away, after about fifty times, inetd goes into a
major snit and stops accepting connections on that port.  Neither the
netstat table nor the process table shows anything untoward.

I can reproduce the problem on the nntp port and the telnet port, so it's
not gopherd's problem.

Sending inetd a HUP fixes it, and it'll just spontaneously recover after
a few minutes as well.

Does this sound familiar?  Is it one of the many joys of SunOS that I
should come to know and love?

Any suggestions are welcome.  ADthanksVANCE!!

Does anyone know what these mean?  Is this just something relatively
harmless like a memory leak?  I'm running 4.1.3 on an SS10 and I would
*really* like to use tmpfs, even though I keep running into problems.
I've found that if you grow a file by seeking past the end, and then write
some bytes, the bytes don't show up in the file even though the space
for them is there.

In my experience this usually means what it says - the tape is bad!
Especially if it happens again on the same tape.
It might also mean the drive heads need cleaning or there is something
wrong with the drive.

As far as I know dump doesn't care about filenames.
At the beginning of the dump it looks at the filesystem to get directory
information, but after that it reads the raw disk.  (Correct me someone
if I'm wrong, as I haven't seen the code.)  So if this error is occurring
after the "dumping (Pass IV) [regular files]" message, I can't see how
filenames could cause it.

In any case, unless dump is even uglier than I thought, I doubt it would
say "tape write error" because it didn't like a filename.  Not even Copilot
dump:-)

Hope this helps.

sent to standard error when they launch Calendar Manager:

rpc.cmsd: file error on /usr/spool/calendar/.caltmp.wilcoxen during garbage collection
possible causes: host server is down, disk is full, out of memory, file protections have changed.
damage: none

Checking against the mailing list responses, file permissions are
correct, rpc.cmsd is being started from /etc/inetd.conf, and
install_cmgr has been run.

Does anyone have similar experiences with Calendar Manager?

I have inherited a cluster of Suns that do incremental backups by
cron.  Each system that wants to back up has a designated time of day
for it to do an rdump to the tapehost.  I would like to change it
because it wastes time between backups, because it allows too much
access for the backup client, and because it is error prone.

Do other people like to contact the backup the backup client from the
tapehost?  I could either do a "rsh client dump ... | dd of=tape" or I
could do a "rsh client rdump ...".  Is there an advantage to either?
My understanding is that rdump and rmt don't talk so efficiently so I
might lean to the former approach.

Any comments?

I have an HP plotter I need to connect to a Sparcstation IPC

It's important that I do this, because one of the products that
is using this plotter tries to initialize the plotter by just
dumping stuff out the port.  After that, it is able to use the
spooler for "real output", and I know how to set up the printcap.

The only things I've seen ANY success with are running a background
shell that does "(stty baud 2400 > /dev/ttyb; sleep 999)", or
setting up ttytab to run a getty on the port at 2400 baud, but
these are both hacks, and seem to cause other problems.

Is there any way to tell the system to set the port to 2400 baud
all the time?  If so, what is it?  Please email.  Thanks for any

It depends on a lot of things: how fragmented swap chunks are in the raw 
partition (and this does happen) vs. in the file on a filesystem (and the 
filesystem structures themselves impose fragmentation); how much virtual 
memory an application needs; how good the application code is in terms of 
locality of reference and accessing contiguous data; how much real memory 
the system has and how many active processes are sharing it - all the things 
that determine how much swapping a system does and how many seeks are needed 
to satisfy each swap request.

If a swap file is just enough fragmented that most requests will need even
one more seek than they would have needed in a raw partition, a heavily-
swapping, long-running application will see a noticeable cumulative effect.

The point is simply that you do pay some penalty for using files instead of
raw partitions, and the more swapping you do, the higher the penalty becomes.
For some people this may not ever be significant enough to notice. But if
the system has enough active virtual memory that new swap files keep having
to be added, it's doing enough swapping to benefit from using a raw partition
instead. "Much less efficient" may be an overstatement for the average single-
user workstation.

It would be nice to get this decently quantified, but it isn't an experiment 
most people can easily set up.

This would be the sensible thing to do; does it? :-) If so, then of course 
some of the filesystem overhead goes away. Some of it is also eliminated by 
the sticky bit being set (e.g. inode information is not updated).

Which system?  Your system of trying to see how much memory your machine
has?

What's wrong with that system is that it can't cope with machines like
many modern machines that don't have one single physically-contiguous
chunk of memory, but has several chunks that aren't contiguous with one
another - "wc /dev/mem" doesn't give a valid answer on those machines. 
Your IPX is one such machine....

But why can't it just use the whole 32 bit inode-number?  
I mean, hey, the (pre SVR4) cpio format doesn't have to be used *internally*
