Hi,

Do you know if there is a patch in order to recover NetWare client on 4.x with NetWorker Server 7.2 on HP UX v11.
We know that in order to back up clients, we must define the NSR_SUPPORT_NETWARE value on the NetWorker script such as:

Sample of /sbin/init.d/networker

#!/bin/sh
# installed by postinstall on Mon Dec 20 14:55:36 SGT 2004
NSR_SUPPORT_NETWARE_4X=1; export NSR_SUPPORT_NETWARE_4X
case $1 in
'start')
(echo 'starting NetWorker daemons:') > /dev/console
.....

After that all backups run fine, but if we want to recover datas (more that 2 Gb by a save set) it is not possible; we have the message (on the daemon log file) :
Error: 'ansrd: Cannot compute first volume needed for the recover'

According to Legato, it's a problem such as :
Here is the problem or goal:
Error: 'ansrd: Cannot compute first volume needed for the recover'

Causes of this problem:
Backup was made with NetWorker 5.5.2, so saveset is divided into several 2GB entries in the media database. By checking mminfo, the first entries for the saveset were missing.

It's true because before to be under NetWorker 7.2, the server was under 5.2 and has been migrated.

But every recover that has a save set >= 2 GB (from a NetWare client) failed: Error: 'ansrd: Cannot compute first volume needed for the recover' (it means recover is possible and function only for save set < 2 GB)

Do you have any ideas ??
Best regards,

Marc
 
Sorry to say that but at this stage, i think you lost your data. It does not matter whether this is the beginning of an old or a new save set - if the begin of the save set is lost, NetWorker can not synchronize any more. The same would apply if you accidentally relabeled a tape.

Maybe Legato can help or a data recovery company but this depands on the situation. NetWorker itself can not help any further.

I am sure that a NetWare client save set > 2GB is not a problem. This should be known by now.
 
The begin of the save is not lost because, we know that datas are on the tapes (we made a scanner with the -i option that was ok (4 days with 6 tapes !); no error and all data less than 2 GB can be restored on the first hand (but we can't restore the save set >=2 GB) and on the other hand, we see all the save set also the begin with the fragflags option of mminfo (flags hb).

On the knowledge base, we have also:

Solution Title: nsrretrieve cannot retrieve savesets larger than 2 GB
Solution ID: legato7082

Here is the solution:
Problem is fixed when the NetWorker Client version is updated to 6.1.

Here is the problem or goal:
nsrretrieve cannot retrieve savesets larger than 2 GB
nsrretrieve fails
Error: 'nsrretrieve: falling back to old retrieve method'
Error: 'ansrd: vol_attr, err: aggr_rlists: bad return from vol_info'
Error: 'ansrd: Cannot compute first volume needed for the recover'
Error: 'RPC error: Unable to receive'

Problem Environment:
NetWorker for UNIX 6.1
NetWorker for UNIX 6.1.1
NetWorker Client for UNIX 5.5.2
Tru64 UNIX
HP-UX

A NetWare Client NetWorker 4.x can not recover an old save set more than 2 GB with a NetWorker Server 7.2 under HP UX if this server NetWorker was before 5.5.2 (has been migrated) and backed up the NetWare Client NetWorker 4.x

Also , I have just received now an information such as:

Solution Title: Save sets broken into 2 GB chunks
Solution ID: legato15261

Here is the solution:

Expected behavior. No fix required.

Here is the problem or goal:

Save sets for client are being separated into multiply 2 GB chunks

2 GB save sets size
2 GB saveset size limitation

mminfo displays save set name followed by number in angle brackets <1>

Solution Title: Recovery hangs / fails when running NetWorker Server 7.1.3 or 7.2 and the save set is bigger than 2 GB

Solution ID: legato79400

Here is the solution:

Known issue: LGTpa72413 Contact LEGATO Software
(EMC Software Group)

We see with them,
Thanks,
Best regards,

Marc
