Re: %BACKUP-I-BTCROUT messages during disk-to-disk backup
The messages are informational and looking at the
source listings tends to indicate that the
BTCROUT messages are trace or debug type output
that should probably not appear and may well just
have been left in due to a conditional build of
that version of BACKUP.
The 420 equates to
%SYSTEM-F-MEDOFL, medium is offline.
At what point in the backups do the messages appear?
Regards
Dave

Re: %BACKUP-I-BTCROUT messages during disk-to-disk backup
The point at which the messages appeared was somewhere during the backup (about halfway):
.
%BACKUP-S-CREATED, created $1$DGA337:[ORACLE.DB_MSW]MSW_AXAPTA_03.DBS;1
%BACKUP-S-CREATED, created $1$DGA337:[ORACLE.DB_MSW]MSW_AXAPTA_IND_03.DBS;1
%BACKUP-I-BTCROUT, routine Write error detected, output Status, Call RESTORE_ERROR
%BACKUP-I-VALUE_TRACE_D, Decimal trace value 420
%BACKUP-S-CREATED, created $1$DGA337:[ORACLE.DB_MSW]MSW_BHAIC1_1.DBS;1
%BACKUP-S-CREATED, created $1$DGA337:[ORACLE.DB_MSW]MSW_BHAIC1_2.DBS;1
%BACKUP-I-BTCROUT, routine Write error detected, output Status, Call RESTORE_ERROR
%BACKUP-I-VALUE_TRACE_D, Decimal trace value 420
%BACKUP-S-CREATED, created $1$DGA337:[ORACLE.DB_MSW]MSW_BHAIC1_7.DBS;1
.
The backup completed succesfully. At the moment we have the disk mounted and started the database on it and it seems to be working fine. I still wonder what happened.
Could there be a problem with the filestructure, I used ANALYZE/DISK and DFU VERIFY and they both reported no errors?

Re: %BACKUP-I-BTCROUT messages during disk-to-disk backup
possible that the connection is being temporarily
lost? ... which would result in the MEDOFL status
being returned.
Can you monitor the state of the disks during
the backup to see if they are briefly going into
mount verify?
You should see this if you have another session
with REPLY/ENABLE.

Re: %BACKUP-I-BTCROUT messages during disk-to-disk backup
Could this restart, although it happened half an hour earlier, have anything to do with the messages that I got? Before starting the backup a SYSMAN io SCSI/Auto was performed to configure the disk and to verify the paths.
What are the chances that the copied data is in someway corrupted? Should I worry about that? The Oracle database on it (just used for querying) started without any problem.

Re: %BACKUP-I-BTCROUT messages during disk-to-disk backup
does not report any "errors" I would assume that
the backup is OK. I don't think the HSG80 reboot
would cause a problem unless it was done during
the backup, which it wasn't. The best thing to
do would be to have another session active with
REPLY/ENABLE or check the operator log to see if
any of the disks go into mount verify for a short
time.

Re: %BACKUP-I-BTCROUT messages during disk-to-disk backup
how about the error counter on the target disk,
did this increase maybe? How about the ports on your FC switch, are these all clear?

Re: %BACKUP-I-BTCROUT messages during disk-to-disk backup
Could this be the cause of the messages?
Does backup have a problem with a disk going into Mount Verify?

SolutionI suspect that the switching and going offline
are the source of the MEDOFL informational
messages. The purpose of mount verify is to
allow for the possibility of a transient state
to repair itself and have things come back to
normal. If the disk were to disappear totally
then backup would fail and report the appropriate
error. Since the backup is not reporting these
things as *errors* but as *informational* I would
not worry about it.

Re: %BACKUP-I-BTCROUT messages during disk-to-disk backup
while I would not worry about the result of this particular backup, I would still check the ports on the FC switch. We did have cases of both GBICs and Fibre cables slowly dying that did manifest as path switches on the OS level.

Re: %BACKUP-I-BTCROUT messages during disk-to-disk backup
Thank you for your responses, I now have a good idea what these messages mean and why they probably appeared during this particular backup.
I will monitor this HSG80-pair's ports on errors. We did restart this HSG80-pair because we had problems with it (we do not restart controllers just for fun ;-( ). Some systems had problems with the connection to port 1 of the top-controller, while other systems did not have any problem with it.
Restarting the controllers did not help, when we rebooted the systems as a final solution the problems were solved.
I logged a call for this problem. What I know sofar is that I looks like that the particular port is being overloaded with I/O's. This can be caused by servers that have a high I/O bandwidth (f.i. a GS1280 system).

Re: %BACKUP-I-BTCROUT messages during disk-to-disk backup
If it is a KGPSA-EA, then the following might apply....
Required Firmware Update for FCA2384 (DS-KGPSA-EA)
customer advisory OI040319_CW01 revision 0
released March 2004 last updated 09 July 2004
description
PERFORMANCE ISSUE REGARDING POSSIBLE DATA CORRUPTION OR HARD APPLICATION ERRORS
While evaluating multiple configurations of Alpha Server systems in a stress-testing lab environment, HP has observed that excessive Fibre Channel abort sequences occurring while heavy sequential writes are in process could possibly lead to hard application errors or data corruption. The affected systems included only Alpha Servers equipped with FCA2384 model Host Bus Adapters (HBA) running OpenVMS or Tru64 UNIX. HP has released a firmware upgrade to address this issue and strongly advises the immediate upgrade of the HBA firmware to this version.

Re: %BACKUP-I-BTCROUT messages during disk-to-disk backup
We use the following adapters:
- KGPSA-CA (LP8000) - on the older systems
- KGPSA-** (LP9000) - on our GS1280 system
- KGPSA-** (LP9802) - on a DS25 system
I'm not sure if one the last two adapters is the KGPSA-EA. Could you tell me that?
Regards,
Rene

Re: %BACKUP-I-BTCROUT messages during disk-to-disk backup
DS-KGPSA-EA is LP9802
Please note that the reverse is not always true, as the FCA2404 is based on the Emulex LP9802, too, but is for Windows 2003 (Itanium).

Re: %BACKUP-I-BTCROUT messages during disk-to-disk backup
Fortunately we have already updated the Firmware of these adapters to v. 1.00x8
Thanks anyway for pointing me at this advisory....

Re: %BACKUP-I-BTCROUT messages during disk-to-disk backup
I also received this information today in the HP email notifications.
Unfortunately there is no accompanying README to tell me why I should upgrade my firmware.
We normally only upgrade the HBA firmware together with the firmware of the Alpaserver it is installed in.
Do you have any clue why I should update the Firmware of this HBA?
