You are contrasting the price of consumer grade 8mm and datagrade
DAT cartridges, which is sort of unreasonable.  Consumer grade
DAT is more expensive than consumer grade 8mm, but not that
bad (around $12-14 for DAT, as I recall), and data grade DAT seems
to be about $16 to $20 US for the 60 meter (1.3 GB) tapes.  Data
grade 8mm cartridges seem to be in about the same price range or a

that Exabyte reliability is worse than DAT.  If you look at the tape

are better, but we won't know for another year or so for real world
use.  SGI sells both DAT and Exabyte, and may or may not share my
opinions on this (i.e., my opinions aren't official statements).

Subject: No formfeed at end of output to lp0 ???

When I send output to my printer on /dev/lp0, I always get a formfeed (ASCII
value 12 = 0C hex) as the last character that is sent to the printer. It makes
no difference whether I use a queue or send it directly to /dev/lp0.
We have a PostScript printer so I don't like this behavior. With SMIT I looked
"everywhere", but I could find a menu where this formfeed is added. And it 
wasn't there when we used aix 3.1.5. After upgrading to 3.2.1 it suddenly
was there and doesn't go away.

Any ideas ?????

Organization: Univ. of Calif., Irvine, Info. & Computer Sci. Dept.
Distribution: usa
Date: Fri, 16 Oct 1992 16:07:18 GMT

We have about 30 IBM RS/6000's here which we acquired over about a 1 year period
early in the RS/6000 development.  Lately it seems as if we've been having
about 1 disk drive go bad every month!  They all seem to fail in the same
fashion.  The first thing you notice is a little noise which sounds like
something on a spring dropping inside the machine.  This sound is followed a
few seconds later by a lot of disk access activity.  If you look in the "errpt"
log you find entries like:

8564E6B1 1014112192 T H  hdisk0         DISK OPERATION ERROR
8564E6B1 1014053192 T H  hdisk0         DISK OPERATION ERROR

8564E6B1 1012160192 T H  hdisk0         DISK OPERATION ERROR

(Lots more of this...  I think you get the point.)

Anyway, I'm wondering if anyone knows anything about this.  Are other people
getting lots of bad 320Mb disks on RS/6000's as well?  Maybe there was a bad
batch of disk drives and we just happen to get a lot of them?  I'm wondering
if this is going to be a continuing problem.  If so, it'd be cheaper in the end
to either buy other drives from third party vendors, or maybe by something
other than an RS/6000.  (Of course, right now these machines are under
maintenance so at least I'm not buying new disks everytime!)

Please respond directly to me since I don't get around to reading this
newsgroup as often as I'd like.  Thanks for any help anyone can provide.

 The following steps will cleanly remove the lpp and cleanup the repository:
 1. Use the Force flag and re-apply the lpp  either using SMIT or
    from the command line using 
    "installp -Fad DEVICE lpp_to_be_removed"

 2. Now the lpp is in APPLIED state which can be rejected. 


CAUTION:
  Use the Force flag very discriminately because you may mess up the
  requisite integrity of the system.  This flag should be used ONLY
  when it is absolutely necessary. 

Note: The force-apply can be used only at the LPP level, not at the 
      update level.

I did as you suggested. The results were clear - The IBM's were
making an RPC call (# 200006) to get ACL information from the Sun.
THe sun didn't know what to do with it, and being somewhat lame,
crashed. SunOS 4.1.3 seems to work ok. I also found a reference
to this problem in APAR IX19303. The fix was to keep the IBMs from re-
sending the RPC when the first one failed. In our case, where
we do multiple mounts from one server, the effect was the same - 
failed mounts and server crashes.

I would like to see the noacl mount option (largely un-documented)
be allowed to the vmount system call, or have the client
negotiate with the server somehow over the use of ACLs, rather
than just making a non-standared RPC call out of the blue. 

Of course, this wouldn't be a problem if Suns had correctly 
handled the illegal call to begin with, but apparently, they have
fixed this. - Woody Kellum

Subject: How to restore a disk...does anyone know?
Date: 13 Oct 92 19:15:45 GMT
Distribution: usa
Organization: Bellcore


 Has anyone out there stumbled across a foolproof method of restoring a 
disk? 

 Here's the situation:

   Several volume groups spread across several adapters and disk drawers. One
of the disk drawers is lost (powered off, dies, etc.). Once the power/drawer
has been returned to service, the disk needs to be re-integrated into the
system.

  All disks are mirrored to another disk in another drawer, so the loss of a 
single drawer or disk keeps the machine up and running. We do not want to reboot 
the machine to bring the disk back online, nor do we want to unmount and
varyoff the volume groups.

 We have tried to do 'mkdev -l hdisk#' for the disks that were powered off,
and then a 'varyonvg vgname' for the volume groups affected, but this does 
not always seem to work. It sometimes gives resync errors and leaves the
disk in a PVMISSING state.

 We have also tried to use 'chpv -vr' and 'chpv -av',
but this appears to be broken under aix 3.2.2 (can anyone confirm?).

 Has anyone stumbled across an answer? 	I would also like to use this to
bring a new disk on-line after the original disk crashes, and migrate the
mirrored data back onto the new disk, without having to take the machine
out of service.

 I will be more than happy to share and summarize any responses.

What is this obsession with diskless clients? I promise, 90% of my
RS6000's will never, ever, ever be servers for diskless clients. Why
isn't this an option, or even a product, like X-station manager? I
seem to see all sorts of parts of AIX tripping over this stuff, and
most of us don't give a good goddamm about it. Example: applying
updates, you keep getting long messages about rebuilding the boot
software for diskless clients. I repeat, who cares?

will clear this condition up. The CD is fine locally on AIX.

I had this problem with 3.1, figured it might be better under 3.2, but
no dice, same problem.

We do this with CD/ROMs on Suns all the time and have never had any

problematic? Is this a known bug? It seems to have survived 3.1->3.2

We never use smit to add users. We configured "/etc/security/mkuser.sys and 
mkuser.default" to copy all the relevant standard profiles etc. to the users 
$HOME and then we run a simple "mkuser". I suggest you use cut and paste to 
make a scripts that will add all of them at once. As far as the passwords is 
concerned I suggest you do a global substitution of all the password locks 
to spaces in the password file, and get the users to assign their own 
password.
