[Veritas-bu] Question in regards to Request terminated by tpunmount call

2011-12-13 Thread Justin Piszcz
Hi,

Has anyone seen this error before?

1323301067 1 386 16 media-server-name 0 0 0 *NULL* bptm error
unloading media, TpErrno = Request terminated by tpunmount call from
another process

I was told by the Oracle engineers its usually indicative of an
impending drive motor failure; however, I was wondering if others had
seen this before as well, nothing has changed on the NBU side of
things for months/years so the motor theory makes sense..

Then if you take that and look in the SLConsole logs (or SNMP) you'll see:

STREAMLINE-TAPE-LIBRARY-MIB::slTrapDeviceFreeFormText = STRING:
\Drive not unl ded for fetch - on rewindUnload\, hliLsm=3

So the drive is not unloaded when the picker wants to pickup the tape,
as drives age does the motor performance degrade?

Justin.

Make sure to run the latest firmware on the tape drives (B6W0).  IBM 'claims' 
that this will solve all media issues.

Hi,

I read on this list awhile back there were some media issues others were
having with the IBM LTO-5 tape drives; after an update, things were better.
Currently running B5BF and notice a lot of '(86) - media read errors' on
separate drives in different locations, has anyone seen this, one could
chalk it up to some bad tape media but because it seems to occur across 2
drives in 1 location I was curious if anyone else had seen this issue and
if so, which F/W where they running that seemed to solve the issue?

2011-12-13 Thread Lightner, Jeff
As robots age everything gets worse.   I'd used the STK L700 or OEMed versions 
of it for years.  However the last few years of the one we had here made our 
lives a bit miserable.  Drives failed more often, the hand had to be replaced 
2-3 times and various other quirks.   (That robot was here when I got here 7 
years ago and I think it was already 3 years old then.)

We did periodically see something like unexpected rewind during write on 
drives and would have to replace them.   Once that unexpected rewind occurred 
all backup images on the tape become suspect.

A good thing to ask vendors when they suggest you patch software or update 
firmware is for the documentation for that patch/firmware that shows where it 
fixes your SPECIFIC issue.

Telling people to patch/update has always been viewed by me as just a vendor 
stalling tactic for the most part.  You should of course do planned 
patching/updating as regular maintenance but usually when it is suggested 
during troubleshooting it has little value and doesn't solve the issue.  In 
more than 20 years I can only think of 2-3 occasions where a vendor when so 
challenged was actually able to show where the suggested patch/firmware 
specifically mentioned the issue I was having.

i use the get on the latest firmware first option as an easy way to get on 
the latest firmware without having to do all of the paperwork for planned 
upgrades.  it's broke and needs patching now!

when they correct a known issue (bug), the fix could also inadvertantly fix a 
different issue, the issue that you are experiencing.  if it doesn't fix your 
issue, then it forces them to now look at it much more closely.

i had an issue a couple of weeks ago where we've been using lto5 drives for 8 
months with no issues, but we are only writing to lto4 media.  we put on our 
first batch of lto5 media and all tapes gave us errors and went to a partially 
written FROZEN state:

ouch!  so i opened a support ticket and they thought it could be bad tapes (all 
of them?), but suggested a firmware upgrade.  how could that fix it?  lto5 
drives should be able to write to lto5 media. would we have had this issue if 
we had used lto5 media 8 months ago with the firmware that was on the drives 
when they were new?  so i upgraded the drives to B6W0 and it fixed the issue.  
i now get twice as much data written per tape in each slot of the library.

2011-12-13 Thread Lightner, Jeff
As noted it does occur on rare occasion that an update has a fix for the issue 
you're experiencing.   The point in my email was that most of time it does not 
and is simply suggested to avoid actual work by the vendor in troubleshooting 
your issue.

While you've seen inadvertent fixes of side issues I can say I've also seen 
inadvertent side breaks.   Years ago during regular patching of systems one 
vendor introduced a patch the broke how later patches got applied.   We ended 
up having to back out all patches in that set and introduce them one by one to 
try to figure out which patch broke it because the vendor didn't know.   Since 
the bad patch was actually the one BEFORE the one that we saw an error on we 
had to prove it was that patch by NOT applying the next one but instead 
applying others in the set AFTER applying the bad one so we could show any new 
patch applied after the bad one gave an error.   From that point on there, and 
everywhere I've been since, the rule is we don't apply any update that is less 
than 30 days old and hasn't already been applied at other of the vendors' 
clients previously.

As I noted patching/updating is important but unless there is a specific fix 
for your issue it almost always is unhelpful and in fact muddies the water 
because once you do actually resolve your problem you're never really sure if 
the final fix was the fix or if it was a combination of patches and other 
changes.

One thing that NetBackup is good for in this regard is usually if they tell you 
to apply a new patch/binary they've made it IS specifically related to the 
problem you're experiencing.   They actually go the opposite way in 
troubleshooting often and it sometimes takes a while for you to find out they 
have such a patch/binary.

I have IBM LTO-5 drives, Production are at B6W2, Test are at A5R0 and A9Q5.

I have seen read/write errors, but mostly as a result of excessive head wear.
I would suggest keeping an eye on how often the drives request cleanings - 
symptomatically if you see them starting to request cleanings more often, they 
will eventually request it every day - you will need to replace the drive...

I am not seeing any error 86 at this time.

Do you have a library that will show you a little more detail on the error from 
the log that is within the tape drive and or the tape library. Also the code 
that shows up on the led display on the front of the tape drive. If any.

We have been having issues with some lto-5 tape drives that appears to be a 
cooling fan issue.
This shows up as a 3584 library issues.
HEC/HECQ B886 (Canister cooling fan failure)

We had  upgraded the firmware to address several other issue. We are now at

Hi Len et all,

 

I looked in the error warn info logs and I could not find anything
interesting, I have seen temp alarms in one site with SL500s, once, but not
at this particular site.

Thanks for the information though, it seems  B5BF is highly recommended
(Oracle also recommended moving to the newer version).

Hi Justin,

 

I used to work many many years ago in Sun support level 2, mainly doing NBU
support. (Have never worked for Oracle, if that helps date my time with
Sun).

So, next I should say that this is my opinion/experience and not that of
Sun's and not a reflection on any one individual.

But I can quickly give some insight/tips:

-  Many but not all customers see the request to update firmware as
stalling. Don't dispute that this is a common opinion. 

-  The engineers are instructed to do this - they have no choice -
so don't get too grumpy at them. This is one of many due diligence things
they are expected to do - it only stands out because it involves an outage. 

-  Some don't like it because they only want to make technically
justified changes - I agree with this, but in moderation/ in context. I
eventually came to the position that 1. systems should be
resourced/sufficiently redundant to allow an outage and 2. A firmware update
is not like the support engineer is asking for an outage to the business's
principal database or a customer facing system, so it's not such an diabolic
request and needs to stay in perspective. 

-  Technically, I see more than one reason to update the firmware. 

o   The obvious reason is it's a problem identified as fixed in the README. 

o   The other one people generally think of is an issue might be
accidentally fixed by the update. 

o   But the one that isn't so well-known is that level 3 support have
diagnostic tools - it's actually possible to collect logs from the tapedrive
and examine these - the update to firmware source code doesn't just improve
functionality and remove code defects, but also improves log/debug
information. It's presumably still the case. I only found out about this
tool(s) as I had a very competent dedicated level 3 engineer two cubicle
walls over from me - it wasn't particularly common knowledge or commonly
needed. 

 

Now to help you with your issue, my recommendation is:

1.   Schedule to do the update.

2.   Whilst you waiting for a window to do the update, run some vmstat
and iostat commands collecting output - particularly monitor %b - there's so
much to interpret just with this, and you're in a better position than an
offsite support engineer to interpret it as you will know when the tape
drive is and isn't in use. This can identify a dying tape drive without
looking at the diagnostic logs. (I've often wished customers would do this
before ringing support as it's the obvious thing to do before updating
firmware) (I'm assuming your media server is on a nix box as you've
mentioned Oracle support.)

3.   If iostat doesn't show an issue and the problem persists after
update, get the problem escalated until you have a level2/3 engineer who can
look at diagnostics.

 

Hope this helps.

Hi Len et all,

 

I looked in the error warn info logs and I could not find anything
interesting, I have seen temp alarms in one site with SL500s, once, but not
at this particular site.

Thanks for the information though, it seems  B5BF is highly recommended
(Oracle also recommended moving to the newer version).

 

Justin.

Justin, 

 

Do you have a library that will show you a little more detail on the error
from the log that is within the tape drive and or the tape library. Also the
code that shows up on the led display on the front of the tape drive. If
any.

 

We have been having issues with some lto-5 tape drives that appears to be a
cooling fan issue. 

This shows up as a 3584 library issues.

HEC/HECQ B886 (Canister cooling fan failure)

 

We had  upgraded the firmware to address several other issue. We are now at
B6W8.

Hi,

I read on this list awhile back there were some media issues others were
having with the IBM LTO-5 tape drives; after an update, things were better.

Currently running B5BF and notice a lot of '(86) - media read errors' on
separate drives in different locations, has anyone seen this, one could
chalk it up to some bad tape media but because it seems to occur across 2
drives
