Configuring Novell Storage Management Services for use with

VERITAS Backup Exec for NetWare Servers

VERITAS Backup Exec for Windows Servers

and

VERITAS NetBackup


Novell Storage Management Services (SMS) has been available since NetWare 3. As
such, it has

gone through significant changes throughout its long life cycle. The document
describes the various ways that the SMS components have been configured through thi
s
time.


Quick Guide for Configuring

This sectio

D
ifferent versions of SMDR.NLM ask different questions. However, they are similar
enough that the following information should be applicable with a minimum of
interpretation:

Unload SMDR and

Type UNLOAD SMDR.NLM at the console. When this is
done, messages are displayed that show which modules must
be unloaded before SMDR.NLM can be unloaded. Typically
these are TSAs such as TSAFS.NLM, TSA600.NLM,
TSA
500.NLM, TSANDS.NLM, etc. Unload the indicated
NLMs and then perform the UNLOAD SMDR.NLM
command again.


Type LOAD SMDR NEW at the console. At this point,
several questions are asked of the user.

SMS Configuration Details


Where SMS Configuration Information is Stored

The two components of SMS that have configuration information to store are the SMDR
and various TSAs. For a complete description of t
hese components see

the NetWare 6.5
Storage Management Services Administration Guide

http://www.novell.com/documentation/oes/pdfdoc/smsadmin/smsadmin.pdf


The SMDR config
uration is kept in the SYS:
\
ETC
\
SMS
\
SMDR.CFG file and in an NDS
object.


TSAFS.NLM which is used to access the file system on NetWare 6 and 6.5 servers keeps
its configuration information in the SYS:
\
ETC
\
SMS
\
TSA.CFG file.


SMDR
Advertising Configuration Se
ttings

SMDR Advertising is used by Backup Exec in the following circumstances:


Backup Exec 8.5 for NetWare and earlier

Backup

Exec 9.1

for NetWare Servers

and later

in a Novell Cluster environment


SMDR can advertise with the following methods:


NDS
-

Nov
ell Directory Services


Works well, but can be tricky. VERITAS
Technical Support typically advises against using this advertising method with
servers in multiple differing contexts because of potential configuration issues.


SAP
-

Service Advertising Pro
tocol. Works well in small to medium sized
networks. Requires the SPX
/IPX protocol
. It is not available on
current

IP only
networks.


SLP
-

Service Location Protocol.
Requires the TCP/IP protocol. Works well for
advertising, but requires that the SLP
protocol be configured properly.

This
advertising method is typically necessary in a Novell Cluster Services
environment.


The simplest method to reconfigure SMDR is to unload SMDR and then type SMDR
NEW at the server command line. When this is done, SMD
R asks a series of questions
whose answers determine which of the above advertising mechanisms are enabled and
disabled.


Note that in order to unload SMDR.NLM, Backup Exec and the TSA must be first be
unloaded.


Recommended Advertising Methods


Backup Exe
c 8.5 for NetWare and earlier

Turn on the advertising methods necessary to locate the NetWare servers that are being
backed up. Do not enable any more advertising methods than necessary. Typically
enabling SAP and SLP are sufficient.


Backup Exec 9.0 for

NetWare and Backup Exec 9.1 for NetWare without Novell Cluster
Services

Disable all advertising. In this environment, Backup Exec does not require that the
SMDR advertise at all. Turning off all advertising can significantly speed up the process
that Ba
ckup Exec uses to locate NetWare servers for backup operations. Note that with
later versions of SMS, SMDR requires that at least the Name Resolution Using HOSTS
File to be enabled or SMDR will not load.


Backup Exec 9.1 for NetWare backing up Novell Clus
ter Services volumes

Enable SLP advertising. Backup Exec uses SMDR advertising in this environment to
locate volumes in the cluster.
SLP advertising should be enabled at the media server as
well as all the cluster nodes that are hosting cluster volumes t
hat are being backed up.

Note that servers that are not cluster nodes, but which are being backed up remotely
should still disable all SMDR advertising as Backup Exec will locate them using the
information in the NDMPSVRS.DAT file.


NetBackup Client ( BPCD

) Targeted Backup

Enable SLP advertising. If you are using BPCD at the NetWare Client to configure the
job you need to be abl
e to see the local SMDR and the SMDR on any remote NetWare
servers that are being backed up.
BPCD does not require SLP enabled w
ithin SMDR for
the physical backup, but it is inconvenient

and generally unnecessary

to enable/disable
every time

a target is created.


NetBackup Client ( BPCD )

Non
-
Targeted

Backup

Enable SLP and SAP advertising. If you are using a windows GUI to configu
re the job,
you need the IPX/SPX protocol to be available and SAP advertising by the SMDR
.


NetBackup NetWare NDMP Agent

Disable all advertising. In this environment, NetBackup does not require that the SMDR
advertise at all. Turning off all advertising
can significantly speed up the process that
NetBackup uses to locate NetWare servers for backup operations. Note that with later
versions of SMS, SMDR requires that at least the Name Resolution Using HOSTS File to
be enabled or SMDR will not load.



TSAFS

Configuration Settings

TSAFS.NLM has a configuration file, and also accepts settings on the command line.


SYS:
\
ETC
\
SMS
\
TSA.CFG
Configuration File

The following settings are available for TSAFS.NLM
. For detailed descriptions of the
settings, please see t
he
NetWare 6.5 Storage Management Services Administration Guide

http://www.novell.com/documentation/oes/pdfdoc/smsadmin/smsadmin.pdf


Cache Memory Threshold

Controls the
amount of space that TSAFS uses for cache.
Lower this number if memory usage issues are suspected.
Note that the smallest value for this setting is 10%. After
the TSA5UP15.EXE release, the smallest value was lowered
to 1%.

Disable Cluster

If Cluster is
disabled, then the TSA reports cluster volumes
as local volumes only. If the volume migrates to a different
server, the backup of the volume will fail. If Cluster is
enabled, then the TSA reports cluster volumes as cluster
resources without the server’s
node name. See TN 263787
for details on setting up Backup Exec for NetWare Servers
in a Novell Cluster environment.

Read Ahead Throttle

Typically left at the default of 5

Read Buffer Size

Should be left at the default of 65536

Read Thread Allocation

Typic
ally left at the default of 100

Read Threads Per Job

Typically left at the default of 5


TSAFS
Command Line Switches


/CachingMode

Introduced in TSA5UP16.EXE. The d
efault setting

is on
.
This
switch
e
nables caching in TSAFS

to increase
performance
.
Howev
er, this read ahead c
aching can
sometimes have a detrimental effect on performance during
differential backups of systems with many directories.
The
caching mode can be turned off using the /NoCachingMode
argument.
http://support.veritas.com/docs/272755


/Cluster

/Cluster is the same as setting “Disable Cluster Off” in the
configuration file. /NoCluster is the same as setting
“Disable Cluster On” in the configuration file.

/DebugFileName

Provides an
alternate location for the debug log generated
with the /SmsDebug switches. For example
/DebugFileName=VOL1: moves the log file to the root of
the VOL1: volume.

/DirQuotaState

Used during a restore to work around problems with
restoring directory quotas.

/DirQuotaState=4 turns directory
quotas off, /DirQuotaState=0 turns directory quotas back on
(Default).

/EnableGW

Introduced in TSA5UP16.EXE. The default setting is off.
This switch provides the ability to back up GroupWise
databases through the file sys
tem. This feature is functional
with the TSA5UP18.EXE release.

/noConvertUnmappableChars

Introduced in TSA5UP18.EXE. The default setting is off.
This switch allows backup of files that have a filename
format of file[1234].txt. The problem is the [1234]

portion
of the name. Without this setting, the [1234] is treated as a
special character.


/SmsDebug

There are two switches that are used to enable debug
logging by TSAFS. They are /SmsDebug and /SmsDebug2.
To turn on debugging on, use the /SmsDebug=FFF
FFFFC
/SmsDebug2=FFFFFFFC parameters. Use /SmsDebug=0
/SmsDebug2=0 to turn it off. See this Novell TID for more
details
http://support.novell.com/cgi
-
bin/search/searchti
d.cgi?/10089094.htm

/UseOldUnicodeAPI

Used during back up of Macintosh files that have names that
can not normally be backed up on NetWare 6.5 SP1.




TSA600

Comand Line Switches

/cluster

Same as /Cluster in TSAFS. The settings are “on” and
“off”.

/dirqu
ota

Same as /DirQuotaState in TSAFS. The settings are “on”
and “off”. The default is “on”.


TSA500

Command Line Switches

/dirquota

Same as /DirQuotaState in TSAFS. The settings are “on”
and “off”. The default is “on”.
