VERITAS NETBACKUP TIPS


Starting and Stopping Netbackup


Stopping Netbackup
  • /usr/openv/netbackup/bin/K77netbackup    --> graceful shutdown
  • /usr/openv/netbackup/bin/bpps -a   --> check for any remaining processes
  • /usr/openv/netbackup/bin/goodies/bp.kill_all   --->  kills all remaining netbackup processes, not necessarily graceful
  • /usr/openv/netbackup/bin/bpps -a   --> check for any remaining processes
  • kill -9 <pid>  for any remaining.   NOTE:  unkillable processes may require a reboot

Starting Netbackup
  • /usr/openv/netbackup/bin/S77netbackup  --> after bp.kill_all, to restart

Common Tasks
Starting the Administration GUI
  • java from the windows client
  •  x-windows from the server - /usr/openv/netbackup/bin/xnb &
Checking Backup Status
  • Activity Monitor or
  • /usr/openv/netbackup/bin/admincmd/bpdbjobs -report
Cleaning a tape manually
  • Identify the drive name to be cleaned
    • tpclean -L
  • Manually clean the drive:
    • tpclean -C <drive name>



Determining what tapes were used for a backup
  • GUI
    • Backup and Restore --> Find the file system --> Preview Media Button
  • CLI
    • Find the correct backup images
      • bpimagelist -U -client <CLIENT> -d <STARTDATE> -e <ENDDATE>
    • Find the media used for those images
      • bpimagelist -U -client <CLIENT> -d <STARTDATE> -e <ENDDATE> -media


Listing the files in a backup

Find the tape(s) used (above procedure using bpimagelist)
cd /usr/openv/netbackup/db/jobs/done
Run the following script and redirect it's output to a text file:
        for file in `grep MOUNTING *|grep <MEDIA_ID>|awk '{print $1}'|sed 's/:MOUNTING//'`
        do
        echo $file
         grep PATH_WRITTEN $file|awk '{print $3}'
        echo " "
        echo "==========================================End of Image======================================"
        echo " "
        done


This process works for NBU V3.4:
  • cd /usr/openv/netbackup/db/images/<CLIENT>
  • ls -ltr  -->  this will identify the directory with the proper date
  • verify directory with "bpdbm -ctime <Unixtime>
  • cd <Unixtime>
  • ls -ltr --> lists all of the backups for this client on this date
  • cat <POLICY>_<Unixtime>_<BU Type>.f | awk '{print $10}'  --> this prints out the files in the backup

For NBU > V3.4
  • bpflist  --help   --> undocumented netbackup command to list files from a binary .f file


Inventory the Robot
  • Inventory Robot  -->  /opt/openv/volmgr/bin/vmcheckxxx -rt robot_type -rn robot_number -list  (where robot_type is tld, acs, . . .)
  • Inventory Robot and Update Configuration -->  /opt/openv/volmgr/bin/vmupdate -rt robot_type -rn robot_number -list  (where robot_type is tld, acs, . . .)

Listing Properties of the Volume Pools
  • vmpool -listall


Scratch Tapes
  • Count scratch tapes:  /usr/openv/volmgr/bin/vmquery -pn Scratch | grep -c "robot slot"
  • Moving tapes to the scratch pool
    • If Needed - Expire the tape
      • bpexpdate -ev <TAPE ID> -d 0 -force -host <Media Manager>
    • Move the tape
      • vmchange -p 2 -m <TAPE ID>


Checking Drive Usage
  • /usr/openv/volmgr/bin/vmoprcmd


Taking a drive down or up
  • /usr/openv/volmgr/vmoprcmd -down <drive index>
  • /usr/openv/volmgr/vmoprcmd -up <drive index>


Performing a Restore
  • From the GUI
    • user backup & restore --> configuration --> client
    • user backup & restore --> configuration --> client to restore
    • directory to search
    • directory depth
    • date range
    • file --> browse backups for restore


Adding New Tapes to the Library
  • Using the GUI
    • Media Management --> Actions --> New --> Single Volume . .  -->
    • Media Type (ie DLT)
    • Robot Type (ie TLD)
    • Media ID (from Inventory)
    • Slot Number (from Inventory)
    • Robot Number (ie 0)
    • Volume Group
    • Volume Pool (ie Scratch)
  • Using the CLI
    • vmadd -m <media id> -mt <tape type> -verbose -rt <robot type> -b <barcode> -rn <robot number> -rc1 <slot> -p <pool number> -mm <max mounts>
      • vmpool -listall  --> lists all pools, both name and number
    • For example:  vmadd -m 000151 -mt dlt -verbose -rt tld -b 000151 -rn 0 -rc1 8 -p 2 -mm 0

Re-using Tapes from other systems or older Netbackups
  • Expire the media
    • bpexpdate -ev MEDIA_ID -d 0 -force -host HOST
  • Deassign the media
    •  vmquery -deassignbyid MEDIA_ID 4 0
  • Move to the scratch pool
    •  vmchange -m MEDIA_ID -p POOL#
  • Relabel the media
    • bplabel -ev CIM572 -d dlt -p Scratch

Changing the attributes of media
  • Changing the barcode
    • vmchange -barcode CYM100D -m CYM100
  • Changing the Volume Pool
    • vmchange -m MEDIA_ID -p POOL#

To expire media
  • bpexpdate -ev <medai id> -d 0 -force -host <media server>


To unfreeze media
  • List the frozen media
    • /usr/openv/netbackup/bin/goodies/available_media | grep -i FROZEN
  • Unfreeze the media
    • bpmedia -unfreeze -ev <media id> -h <media server>

To relabel a tape
  • bplabel -ev <media id> -d <tape density> -p <pool name>
  • bplabel -ev 000687 -d dlt -p TriVrgt_OFFSITE


To remove media from the Netbackup database
  • Verify that there are no images on the tape
    • bpimmedia -mediaid 000687 -L 
  • Expire the tape
    • bpexpdate -ev 000687 -d 0 -host scorpius -force
  • Get the status and pool number of the tape
    • vmquery -m 000687
  • Deassign the tape
    • vmquery -deassignbyid <media id> <pool number> <status code from vmquery -m>
    • vmquery -deassignbyid 000687 4 0x0
  • Delete the tape
    • vmdelete -m 000687


Installing the Netbackup Client
  • /update_clients -ForceInstall -ClientList /tmp/clients.lst
    • requires that TMPDIR and TEMPDIR be set correctly

Excludng files from backup on a client
  • Create /usr/openv/netbackup/exclude_list
  • Put the file specifications of the files/directories to be excluded
    • /mnt/directory/*

Displaying Information about a Tape
  • vmquery -m <media id>   --> Displays attributes about a particular tape
  • bpmedialist -U -mcontents -ev 000687   --> Displays media contents
  • bpmedialist -U -mlist  --> List of all media
  •  bpmedialist -U -mlist -ev CYM966  --> Listing of a particular media id
  •  bpimmedia -mediaid 000687 -L   --> Listing of images on a tape


Robtest Commands
  • Starting robtest
    • robtest
    • 1  --> to select TLD 0
  • Getting help
    • ?
  • Looking at contents of the tape drives
    • s d
  • Looking at the contents of the library
    • s s
  • Moving a tape from a drive to a library slot
    • s d  --> to identify drive number that has tape (Contains Cartridge = yes, Barcode=XXXXXX)
    • s s  --> to identify an empty slot in the tape library (Netbackup will need to be re-inventoried)
    • m d# s#  --> from from drive # to slot #
    • s d  --> verify the tape drive is empty
    • s s --> verify the library slot has the tape

Configuration Files
/usr/openv/netbackup/bp.conf 
  • configuration file, sets backup server and backup clients
  • force statement must be correct
  • client to browse from
  • client to restore to
/usr/openv/volmgr/vmconf

Logfiles

To utilize logfiles, create the corresponding directory in /usr/openv/netbackup/logs

Server Logfile directories:
  • admin - adminstrative commands
  • bpbrm - backup and restore manager
  • bpcd - client daemon
  • bpdbjobs - database manager program process
  • bpdm - disk manager process
  • bpjava-msvc - Java application server authentication service
  • bpjava-usvc - process that services Java requests
  • bprd - request daemon process
  • bpsched - scheduler process that runs on master servers
  • bptm - tape/optical media management process
  • user-ops - required directory for use by Java programs
  • xbpadm - X based administration utility
  • xbpmon - X based job monitor process
Client Logfile directories:
  • bp - client user interface process
  • bparchive - archive program
  • bpbackup - backup program
  • bpbkar - program that generates golden images
  • bpcd - client daemon
  • bpjava-msvc - Java application server authentication service
  • bpjava-usvc - process that services Java requests
  • bplist - program that lists backed up and archived files
  • bpmount - program that determines local mountpoints  and wildcard expansion for multiple streams
  • bphdb - Oracle database backup program start process
  • db_log - database specific extension log
  • tar - tar process log during restores
  • user_ops 
Media Manager logging automatically goes to the system log using syslogd logging facility
.Logging will only occur if these directories are created.  These directories will generate a lot of data and should be deleted when no longer necessary.

To increase the amount of logging information set VERBOSE=2 in /usr/open/netbackup/bp.conf  (default is VERBOSE=1)

Processes
ltid
acsd
vmd

Useful Commands

bpcllist - list classes
bpclinfo <class> -L   --> displays info about a class
vmpool - volume pools
vmpool -listall
vmpool -listscratch
bplabel -ev <media id> -d hcart
bpbackup db  --> backs up the catalog
bpclclients <policy>  --> lists the clients for a particular policy (class)


Troubleshooting

bperror -statuscode   <-- displays information about the  netbackup error.

No Backups are running:
  • Check system log file for error messages
  • Stop and restart all the netbackup processes
  • Look for a downed drive
    • /usr/openv/volmgr/bin/vmoprcmd
    • /usr/openv/volmgr/bin/vmoprcmd -up 0   --> this will bring up drive 0 if it's control shows as down
  • Look for pending requests
    • /usr/openv/volmgr/bin/vmoprcmd or gui --> device management
    • If there is a pending request either re-assign it to a drive, or deny the request
Downed drive does not come back up or does not stay up
  • Check for a hardware problem by looking for messages on the tape library
  • Make sure there is not a tape stuck in the drive
    • Use robtest (described above) to look at the drives
      • If there is a tape stuck in the drive, try to remove it using robtest
      • If robtest fails, then you must manually remove it.
Verify the Client is communicating properly:
  • bpclncmd -ip  <ip address>  --> from both client and server
  • bpclntcmd -hn <hostname>  --> from both client and server
  • bpclntcmd -pn    -->  from client only

Device Actions
Device Management --> info about tape drives
  • dlt
  • hcart (ultrium)
Media Actions
Media id must agree with # of the tape
Create a media id
  • actions -->new-->single volume-->dlt cart (not dlt2)
  • put it into the "netbackup" volume pool



Netbackup Client


To check things out do this:

It could be a couple things.  Mostly DNS, bp.conf, or something stupid.  On
the client run this command

/usr/openv/netbackup/bin/bpclntcmd -pn

/usr/openv/netbackup/bin/bpclntcmd -server "server name"

/usr/openv/netbackup/bin/bpclntcmd ip "ip_address"


One of these usually fails and your able to fix it right off 

1074  ./bpclntcmd -hn corpbu1
 1075  ./bpclntcmd -ip 10.194.1.129
 1076  ping 10.194.1.129
 1077  ./bpclntcmd -hn corpldv1
 1078  ./bpclntcmd -hn corpbu1.corporate.vox.net
 1079  ping corpldv1
 1080  ./bpclntcmd -ip 10.194.1.120


Must be able to resolve correctly from the master server and the client or it will not work!!!
