OpenVMS Backup error

Jesus Nieto_1 — Thu, 17 Nov 2005 17:07:14 GMT

Hi:
I am having the next output for the command:
$ backup/log file.txt file.bck/sav

%SYSTEM-F-ACCVIO, access violation, reason mask=04, virtual address=000000007AED
C418, PC=00000000000F4908, PS=0000001B

Improperly handled condition, image exit forced.
...

In a satellite node (7.2-1h1) connected to a cluster system with the same OS version.
The weird is that I have six satellites nodes and this is only happen in two of them.
All these nodes have the same OS, and patches.
Also the command do not fail if I send the data to a magnetic tape.

Regards

%SYSTEM-F-ACCVIO, access violation = tried to access a memory location and was denied.

mask 04 == write function

Do you have permissions to write to the location in question?
Have you tried
backup/ignore=interlock file.txt -
file_test.bck/save

Are you using a common UAF?
Are the SYSGEN parameters the same on all the
satellites?
Try increasing the PGFLQUOTA value for the systems
experiencing the problems.

Jesus,

Does this happen for any BACKUP command? Is the file particularly large? Could be a quota issue. See the BACKUP manual for recommended quotas.

It could also be a corrupt image, or global section.

If this is a common system disk, try:

$ DEFINE BACKUP SYS$SYSTEM:BACKUP.EXE;

and repeat the command. This will bypass the installed image. If the behaviour changes, have the system manager execute:

$ INSTALL REMOVE BACKUP
$ INSTALL ADD BACKUP

If it's not a common system disk see if the BACKUP image is different from those on other nodes.

Also check for device errors.

Getting any improperly handled condition from backup should be considered a bug and reported to HP.

Sounds like it is not checking for allocation failure and using an invalid pointer. Try using /blocksize=8192 and see if the virtual address changes from 7AED.

Thank you very much to all of your kindly answers.

Let me give you my feed back:

Peter:
Yes I have permissions to write in all the disks, also my account have bypass privilege.
Yes I did tried /interlock qualifier.

David:
Yes the sysuaf data files is common to the whole cluster.
Yes I did tryed to icrease the pgflquo.
The values I have in the account are:
wsdef: 512000
wsquo: 512000
wsextent: 655360
pgflquo: 655360

John:
No until I found only happens with the qualifier /Save.
Yes, I have tried define the backup command, but it did not work.
I have verified the images, and they are the same. (0 differences)
The images are well installed with the INSTALL utility.

Thanks David:

I have not tried to contact HP yet, I am trying to do a research by my self.
Because I found really weird this issue.

Regards.
