In most cases when I get this problem it has something to do with the driver
used on the WIN 2000 server. Check with the veritas Config Matrix and make
sure you are using the right driver. Also check the software loaded for the
NIC cards since you have an EMC switch involve. Make sure you are using the
right version of drivers from EMC.

Subject: [Veritas-bu] Strange behaviour when I make incremental backup of
Notes 5 with transaction log actived

Hi,


I try to make Notes 5 hot backup with Netbackup 3.4 patch J0850645 and the
notes database agent.

The file list of my class is :

E:\notes\data
BACKUP_TRANSACTION_LOGS


When I make a full backup : ok, Netbackup backup all database files and some
transaction log files.

When I make an incremental backup : Sometime, Netbackup backup database
files, so not only the transaction log files.

I known that the database file backup is normal when the DBID change, but in
my tests is not the case.

Do you have somes ideas.

Thanks,

Subject: [Veritas-bu] UPDATE: Mixed Env. Introducing new Media server
and...problems..

Hi everyone,

Thanks for the people who responded to my initial call for help.

Here is an update that perhaps will assist in troubleshooting this. When we
kick of a backup using the W2K media server at the library I can see the
robot going an picking up the correct tape and mounts it in the drive. But
nothing is updated in the device management screen (ie. tape not showing
that it was read and label and barcode identified but the drive is showing
there is a tape in it). It then waits for about 5-10 minutes and then the
drive goes down and tries to mount another tape on another drive.

Any ideas?

thx.

Ed.

new Media server and...problems..     
 

 




Hi Everyone,

We have two environments:

Env 1: Master (Solaris 2.8) with a couple of media servers all controlling
HP 20/700 with 8 dlt8000 drives via SAN (brocade switches) Environment is
working well. 3.4.1GA (data center) with multihosted drives configured etc
etc..

Env 2: Bringing in a Media server 3.4.1 on W2K configured SAN to see the
library and the robot and configured the multihosted drives and robot
control is set to to the Env 1.

Trying to do a simple backup and getting tapes being requested and never
mounted and drives going down. I can see that the media server has started
sending a few files but it never goes further then that.
ie.

11/13/2001 1:47:00 PM - connecting
11/13/2001 1:47:01 PM - connected; connect time: 000:00:01
11/13/2001 1:47:06 PM - mounting XXX096
11/13/2001 1:47:16 PM - mounting XXX095
11/13/2001 1:55:12 PM - mounting XXX094

and so on and on until all drives are tld-down status but nothing was
actually backed to tape.

vmdareq shows:

tape1 - AVAILABLE
     host1
     host2 SCAN_HOST
     mynewhost
tape2 - AVAILABLE
     host1
     host2 SCAN_HOST
     mynewhost
tape3 - AVAILABLE
     host1
     host2 SCAN_HOST
     mynewhost

and so on for 8 drives...

NOTE: I have 2 nics in the new media host (w2k), one is the primary and the
host name is configured as "mynewhost" but I use the other NIC for backups
and it connected to a firewall which does NAT to connect to this other
master (host2)(solaris). However, the hostname being seen is my "production
segment" and not the backup segment (so I am not sure if this is the
problem.. etc).

Any ideas, suggestions would be appreciated.

thx.

Subject: [Veritas-bu] Netbackup and NDMP?


  We're redoing our backup servers to get off of a single older tape library
onto a Gator (huge honkin library) and dual-backup servers.  The theory
is that we'd use one server to back up the standard clients, and then use
the second server to back up the EMC using NDMP. 

A couple questions have come up...

How well does Netbackup (3.4 I believe) work with NDMP/EMC?

Can the 2 servers be clusterd with veritas clustering, 2 dual attached
A1000's and provide hot failover incase either backup server fails?


Any experienced thoughts on this?

Subject: [Veritas-bu] inconsistent (?) catalog backups

I need clarification of what is meant by an "inconsistent catalog 
backup" on
p. 161 of the NBDC System Administrator's Guide.

If any of the forbidden operations would render the catalog backup 
useless
for disaster recovery the suggested procedure is worthless without an
interlock mechanism.

If such a procedure is used by the automatic catalog backups why hasn't
it been used in the script provided?

How can one be sure that both the images backup and catalog backup are
"consistent"?

Finally, if the catalog is on a VxFS filesystem, would snap'ing it avoid
the consistancy issue?
