[Veritas-bu] VCS Clustered NetBackup Master Server
2008-01-29 16:28:10
We have our master server clustered with VCS 5.0 using Solaris 10. It works
very well for us.
All of the media server information is now stored in the EMM database. No
matter where you backup up the catalog you will be backing up the device
information for all of you media servers.
Recovering the catalog can be a little tricky. We recover with a tape drive
attached directly to the master server. You will need to setup the filesystems
on your recovery system to mirror those on your production server.
We use a filesystem on shared storage which mounts on /opt/VRTSnbu/
for the netbackup catalog.
I have copied for you below my notes from the last time I recovered the
netbackup catalog in a DR test.
Assign nbmaster name and ip address to an interface on dr-mars.
install netbackup on dr-mars ? master server name nbmaster
run ../sg.build ?all ?ml 2
run ./sg.install
After installing netbackup the following symbolic links must be created.
ln ?s /opt/VRTSnbu/var/global /usr/openv/var/global
ln ?s /opt/VRTSnb/db/staging /usr/openv/db/staging
These symbolic links are used to point to the database locations which are used
in our clustered environment. bprecover will only recover to the original
locations.
run next command with database up
nbdb_admin ?dba nbusql
stop netbackup ? ?/usr/openv/bin/goodies/netbackup stop?
all netbackup processes must be stopped before proceeding?use bpps ?a to make
certain all netbackup and media manager processes are stopped. Run bp.kill_all
to stop processes that will not stop.
delete all file in the directory /opt/VRTSnbu/db/data except for vxdbms.conf.
rm: remove EMM_DATA.db (yes/no)? y
rm: remove EMM_INDEX.db (yes/no)? y
rm: remove NBDB.db (yes/no)? y
rm: remove NBDB.log (yes/no)? y
run command nbdb_admin ?auto_start NONE ? prevents NBDB from starting
run nbdbms_start_stop start
create_nbdb -drop ?data /opt/VRTSnbu/db/data ?index /opt/VRTSnbu/db/data
?tlog /opt/VRTSnbu/db/data
If the above command fails ? run these commands:
create_nbdb ?drop
nbdb_admin ?dba nbusql
create_nbdb -drop ?data /opt/VRTSnbu/db/data ?index /opt/VRTSnbu/db/data
?tlog /opt/VRTSnbu/db/data
netbackup stop
netbackup start
tpext ?loadEMM
cd /usr/openv
Run /usr/openv/volmgr/bin/driver/sg.build
use tpconfig to add robot and entry for drive 1.
-- determine using robot.pl
tpconfig ?add ?drive 0 ?type hcart ?path /dev/rmt/?cbn -robot 0 ?robtype TLD \
-robdrnum 1 (make certain this is the first drive in the robot) -- determine
drive device by correlating information from drive.pl and robot.pl.
start ltid
vmupdate ?rn 0 ?rt TLD
start ltid
locate correct catalog file -- Catalog_backup_Vault_1_1198419629_UBAK
December 23, 2007.
/usr/openv/DR/catalog/Catalog_backup_Vault_1_1198419629_UBAK
bprecover ?wizard
put correct bp.conf and vm.conf file back in place
after recovery stop and start netbackup
