Re: Erasing pains

[Michael Kennard]

The way I did it was to recreate a catalog and cancel it once it 
started reading the tape. Then you have a bit of a catalog which is 
enough and you can then erase it as normal.

How'd this happen?

[Pam Lefkowitz]

G'morning all,

I have an odd bird here and, though it probably doesn't make a whole lot of
difference in my backup integrity, it is frustrating and annoying
nonetheless.

I have 7 drives in my local container. When I rewrote my scripts about 6
weeks ago the drives/partitions were in this order: 1,2,3,4,5,6,7. Today
when I open configure>volumes it still lists them that way. However, about a
month after I rescripted (say, end of January) my desktop container now
resolves (in all my scripts) to the following order: 4,5,6,7,1,2,3. Nothing
odd happened here hardware- or software-wise that I can think of. And the
only way I know of to fix this is to  rescript again...which I really
really don't want to do if I can avoid it.

Specifics:
G4/450
OS 9.0.4
Retro 4.3

Is this a function of a corrupt Retro.Config error  or have I just
missed something incredibly simple?

Thanks,

Pam

Since you posted this on retro-talk, I have to suggest that you put the tape
drive on a Windows or Macintosh computer and try Retrospect. If that works, your
drive is fine.

RE: 0.8 MB/min?

[Grein, Randy]

Steve,
There's a strong possibility that you're suffering from one or more of the
dreaded 'stupid switch, stupid plug&play' syndrome. If you can, put it on a
fast ethernet hub (NOT a 10/100 hub!) and test. If that works, fix the
switch port to 100 half duplex.

Subject:Re: 0.8 MB/min?

I was plesantly surprised when someone from Dantz Tech Support
(SHAME on me for not noting who it was!) phoned me to discuss this post.
Let me pubicly thank Dantz for taking the step to phone me to help.
Unfortunately, we did not pinpoint where the problem lies, but there are
some updates to the story, which I'll share in hopes that it will someday
help someone else (cuz we all search the archives, right?):

This morning I started an immediate duplicate of the source machine
(B&W G3) to my archive tape set.  It started at a typical 65MB/sec, but
again the speed fell through the day, looking like this:

11:00A - 65MB/min
1:37P  - 15.4MB/min
3:16P  - 10.7MB/min
4:52P  - 8.1MB/min
5:30P  - 7.4MB/min- which is as I type right now.

I have screenshots that show the speed and monitor window from
IPNetMonitor, in case they may be of value.

Prior to the backup, I ran DiskWarrior 2.0 on the client, which did
find problems in the Volume Information of the only disk.  Although DW
reported them fixed, my speed declines persist.

To address your questions and points, and give more info:
The original post came on a Saturday morning.  Over Friday night, my
network traffic was at it's lowest possible, so I doubt network congestion
is the problem.
My local operations are at the speed I expect.  The backup server
can copy to from an ASIP server at about 7MB/sec.
Source and destination for the duplicate were both Retro clients.
There would be no communication problems with a tape drive in the original
post.
Network is 100B switched.
Backup server has 224MB of RAM, 15MB set for Retro preferred.
Between the original duplicate and the above Immediate Backup, I ran
a normal incremental backup on my LAN.  Copied 7 gigs from an ASIP server at
71MB/sec average. Entire copy here is just over 3 gigs.

Erasing pains

[Welch, John C.]

How...do I get retrospect to let me erase tapes from a multi - tape set that
are being recycled and the index has long been tossed?

HP surestore t4i

[Stuart Steele]

I have the above device and when I put in a tape I get a little shudder 
from the drive and no response ( wind on etc, etc) The fundamental 
problem is that if load Arcserve it tries to update the state of the 
tape it does this for about o an hour then hangs the server 
saying aspi board failure 0.

If I leave Arcserve completely unloaded I have no problems and no 
backup.  Does anyone have any suggestions to this problem.  I know if I 
sit there and restart the server repeatedly it will pick up.  but the 
amount of time that the server remains active varys.

I need help.

It's probably a very simple solution however I am at the end of my 
tether it's a small high pressure envioronment so having the server off 
for periods is not the best scenario.

If anyone has a similar problem can they contact me 
([EMAIL PROTECTED])

Thankyou very much

Stuart Steele

Previous failed solutions

clean drive with compressed air duster (HP)
re-install Arcserve (ME & HP)
Complete Power off (ME & HP)
Complete change of Tapes (Me & HP)
Netware Patch for CD rom drives (ME)

My tape went out of warranty recently and now HP would like to charge me 
for the pleasure.

Re: fixing EOD on DAT

[David Ross]

You may have already done this but have you powered everything off and
back on? These small tape drives are really computers with a very
limited user interface and to be honest things like this have a tendency
to have bugs in the error recovery process. Turning everything off and
back on my reset the tape drive to a known state.

This is not a knock against HP but something I've been seeing for 25
years of computer work. Error recovery is one of those areas where
design and testing gets skimped a lot.
