Did my make_tape_recovery work?

WSS — Thu, 08 Dec 2005 05:26:47 GMT

Hi there ... Going by my recovery.log, the make_tape_recovery that I ran, completed unsuccessfully!! These are the last few lines of my recovery.log -

* Preparing to create a system archive.

* Archiving contents of ugos389 via tar image to local device/dev/rmt/0mn
.
* Creation of system archive complete.
Program Terminated. SIGHUP received. Exiting.

======= 12/07/05 16:21:39 GMT make_tape_recovery completed unsuccessfully

The command I used was -

make_tape_recovery -I -v -x inc_entire=/dev/vg00 -a /dev/rmt/omn

I'm using hpux11i on Rx4640 server

It looks like it completed ok with the "Creation of system archive complete" message, but then I get the unsuccessful message after that.

Plus it took a very long time to do just vg00, something like 3hrs10mins

I'm currently running a 'tar tvf' to get a table of contents, but again this is taking ages, been running already for just over 2 hours. I thought this would be quite quick.

This is the first time I have used this tape drive on this server.

Anyone??

Cheers
Trev

hi,

the command used looks ok except for type it should be 0mn instead of omn.

however, the time taken to run it is pretty long unless your vg00 is really that big.

u may like to clean the tape drive and check if any lights from the tape suggesting faulty or dirty tape drive.

btw, what version of ignite r u running?

regards.

Yeah sorry that's a typo, it's definately 0mn :-)

What's the best way to find version of ignite?

I just want to know whether this worked, and safe to use on recovery if needed....

The conflicting messages at the end have confused me somewhat!!

That document shows me how to download and install ignite, which I obviously already have.

In regards to the tape drive, it's a brand new drive....

Thanks

Can't check tape drive as it is in Newcastle, and I am in London unfortunately, but I will get someone else to check it. Version is -

Ignite-UX C.6.1.44

I am starting to think that there is a handshake problem on the tape drive (which by the way is brand new and this is the first time I have used it). It seems to be streaming data for a while, then stopping as I don't get any data going to my 'tar tvf' output file for some time, then suddenly it grows

I might post another thread asking about the tape drive issue of continual streaming and handshaking, as I vaguely remember seeing a problem like this a number of years ago.

Thanks alot

Ok, back to my original question ...

Why did my make_tape_recovery not exit cleanly, and is what I have a successful image??

Here is the end of the recovery.log file -

* Preparing to create a system archive.

* Archiving contents of ugos389 via tar image to local device/dev/rmt/0mn
.
* Creation of system archive complete.
Program Terminated. SIGHUP received. Exiting.

======= 12/07/05 16:21:39 GMT make_tape_recovery completed unsuccessfully

See above for commands used etc...

Thanks

hi trevor,

i would not use this copy through it seems to be archive except for

when the session ends and the end of the recovery.log says "make_tape_recovery completed successfully!", i would use it.

from a later thread u posted, i.e. http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=981868

it seems u r trying to archive 32GB of data from vg00. that is way too big to run on a DLT80 VS (with transfer rate of 3MB/s). this could be the problem for the "Program Terminated" issue at the end of the recovery.log. u may like to check for any core files or unwanted files in vg00, i.e. housekeeping.

for info, i am running make_tape_recovery using a DDS4 tape for about 7GB data in vg00 taking abt 40mins.

regards.

Sorry, I posted a wrong amount. I have 32gb worth of space allocated in /dev/vg00, but the total data in /dev/vg00 is only about 11.5gb ....

So, with that in mind, this make_tape_recovery shouldn't take 3 hours, even at that pitiful rate of 3mb/s.

Any ideas??

Re: Did my make_tape_recovery work?

Joseph Loo — Fri, 09 Dec 2005 05:44:36 GMT

hi,

if that is the case, it should take about 60 to 70mins. so, unless u have ask someone from Newcastle to verify the condition of the tape drive, it is difficult to explain why it is taking so long.

also, have u try make_tape_recovery again on the same tape drive to verify the conditions?

regards.

WSS — Fri, 09 Dec 2005 05:47:10 GMT

Yeah that's what I worked out, just over an hour to do that much data ....

Just running another make_tape_recovery as we speak ;-) So will see if we get the same issues.

I am going up to Newcastle on Wed/Thu, so if it's till giving me problems, I can have a look at it then.

Cheers for the feedback.
