Clustered Netbackup master server softlinks

E-mail Print PDF

Clustered Netbackup Master Servers has a little un-documented link that will cause issues when performing catalog restore if the nbu_server resource is either stopped or failed.

VCS creates a link from /usr/openv/var/global to /opt/VRTSnbu/var/global

Before performing any restores of the NBDB/EMM database create the link manual:

# cd /usr/openv/var

# ln -s /opt/VRTSnbu/var/global global

Catalog restores will then work according to the manual in the troubleshooting normal.

 

Setting the Instance or Database field in Netbackup 7.6 activity from RMAN

E-mail Print PDF

You may have noticed the new field called "Instance or Database" in Netbackup 7.6 activity monitor. This field will populate with the SID during backup using Intelligent Policies. But the joy does not stop here – you can also populate this field using custom scripts.  Just set NB_ORA_SID= during the RMAN send in the RCV script.

 

This is a sample script - database SID is NMATEST:

# -----------------------------------------------------------------
# RMAN command section
# -----------------------------------------------------------------
RUN {
ALLOCATE CHANNEL ch00
TYPE 'SBT_TAPE'
PARMS 'SBT_LIBRARY=/usr/openv/netbackup/bin/libobk.so64';
SEND 'NB_ORA_CLIENT=lyra.noc.nnit.com,NB_ORA_SID=NMATEST,NB_ORA_SERV=srv1.mass.dk,NB_ORA_POLICY=ORA_MANUAL,NB_ORA_SCHED=daily';
BACKUP
INCREMENTAL LEVEL=1
FORMAT 'bk_d%d_u%u_s%s_p%p_t%t'

How to run iperf towards a Data Domain

E-mail Print PDF

Having a good IP connection to your data domain is vital for good operation. Once excellent tool to either relax or concern you, is the Ipef tool. This is a small guide on how to use this great tool.

Prerequisite:

Backup server must have iperf installed. For Linux you can install the package with:

yum install iperf.x86_64

Logon on to DDOS by ssh and run the following command:

# net iperf server  run

On the backup server run:

# iperf -c {DNS name of Data Domain}  -t 10 -i 2

-t indicates to run iperf for 10 seconds

-i 2 will cause iperf to report in 2 sec intervals.

This will output something like:

------------------------------------------------------------
Client connecting to dd01.acme.com, TCP port 5001
TCP window size: 512 KByte (default)
------------------------------------------------------------
[ 3] local 10.1.1.1 port 10066 connected with 10.1.1.2 port 5001
[ ID] Interval Transfer Bandwidth
[ 3] 0.0- 2.0 sec 1.20 GBytes 5.14 Gbits/sec
[ 3] 2.0- 4.0 sec 1.18 GBytes 5.05 Gbits/sec
[ 3] 4.0- 6.0 sec 1.17 GBytes 5.04 Gbits/sec
[ 3] 6.0- 8.0 sec 1.18 GBytes 5.07 Gbits/sec
[ 3] 8.0-10.0 sec 1.18 GBytes 5.06 Gbits/sec
[ 3] 0.0-10.0 sec 5.90 GBytes 5.07 Gbits/sec

This show there is 5Gbit of available network bandwidth and its safe to conclude no network issues exist between backup server and Data Domain appliance
