How to check Netbackup 7 server connectivity from linux client

bptestbpcd command used to test the connectivity between master netbackup server and all client server.

From the linux client :

cd to /usr/openv/netbackup/bin. Run the  utility three times from the client: once (with the -pn arguement) to see if the client can get a response from the master server via the name specified in the client's bp.conf file; once (with the -hn arguement) to see if the client can resolve the host name of the master server; and once (with the -ip arguement) to validate the association of the ip address obtained from the output of bpclient -hn, with the hostname used on the input command line to bpclient -hn



1)# ./bpclntcmd -pn
expecting response from server trout
pike pike 166.98.48.33 34455

Note: If, for example, the master server's name is entered incorrectly in the client's bp.conf file, this run of bpclntcmd will produce no output and simply retrun to the command line prompt

2)# ./bpclntcmd -hn trout
host trout: trout at 166.98.48.63 (0xa662303f)
checkhname: aliases:

3)# ./bpclntcmd -ip 166.98.48.63
checkhaddr: host   : trout: trout at 166.98.48.63 (0xa662303f)
checkhaddr: aliases:


Thanks!!!

STATUS CODE 48: A Status 48 "Client hostname could not be found" message occurs during backup.

Problem:

STATUS CODE 48: A Status 48 "Client hostname could not be found" message occurs during backup.

 

Solution:

1. Ensure that all servers and clients are added to name service tables or local hosts file

2. Verify that name resolution is valid (hostnames are case-sensitive depending on the OS used). Try to "ping" the client from the server where this error occurs. Use the hostname for the client, as specified in the NetBackup Policy for the failing backup.

OR

1. Add host name/IP entries for the Master Server, Media Server and Client in their respective /etc/hosts files.

   Location of host file:

   UNIX:   /etc/hosts

   Windows:  %SystemRoot%\system32\drivers\etc\hosts

Ensure that all hosts involved have host entries for both themselves and one another.

Lvm creation in Redhat 6.3

Here we are going to create lvm for /dev/sdb (newly assigned partition)

# fdisk  /dev/sdb
Create physical partition as /dev/sdb1 from /dev/sdb/
Create Physical voilume:
# pvcreate /dev/sdb1
Create volume group and add the pv to VG :
# vgcreate /dev/mapper/vg_rsatest_disk2 /dev/sdb1
To display volume group information:
# vgdisplay
Create lvm using PE value :
# lvcreate -l 2434 /dev/mapper/vg_rsatest_disk2
Formatted the newly created lvm:
#mkfs.ext4 /dev/mapper/vg_rsatest_disk2-lvol0
Create new directory to mount lvm:
#mkdir -p  /data
Add the below line into /etc/fstab/
/dev/mapper/vg_rsatest_disk2-lvol0 /data         ext4    defaults        0 0
"lvol0"
