Backup and Recovery

1. To backup a filesystem :
# fbackup -f /dev/rmt/0m -i /home

2. To list the contents of the tape media and store it in a file :
# frecover -I /tmp/indexfile -f /dev/rmt/0m

3. To do level 0 (full) backup of a filesystem and also update the file /var/adm/fbackupfiles/dates :
# fbackup -f /dev/rmt/0m -0 -u /home

4. To do a level 1 backup using a graph file to specify which files will be included/excluded :
# fbackup -f /dev/rmt/2m -1 -u -g /var/adm/fbackupfiles/graphs/g0

Graph file content may look like
i /data
e /data/tmp

5. To backup to the tape drive on the remote server :
# fbackup -f host1:/dev/rmt/0m -v -i /home

6. To backup data to two tape drives (one by one) :
# fbackup -f /dev/rmt/0m -f /dev/rmt/1m -i /data

7. To restore all the files from the tape media
# frecover -v -r -f /dev/rmt/0m

8. To show the tape drive status :
# mt -f /dev/mt/0mnb status

9. To eject a tape :
# mt -f /dev/mt/0mnb offline

10. To rewind the tape media :
# mt -f /dev/rmt/0mnb rewind

Points to remember :

Different states of kernel modules :
unused         -  This module is not used, but installed in the system.
static            -  This module will be statically bound to the kernel executable
loaded         -  This module will be dynamically bound to the kernel while booting
auto             -  The module will be dynamically loaded into the kernel when it is first needed after each boot.

NFS in HP-UX

There has been a vast difference between HP-UX 11i v3 with the older versions.Prior to v3, HP-UX used NFS concepts (commands and files) a like AIx. From v3, it following Solaris-like environment.

Configuration Files :

/etc/exports                  -  Contains a list of exportable file systems. This file is available in upto HP-UX 11i v2
/etc/dfs/dfstab               - Contains a list of sharable file systems. This file is available from HP-UX 11i v3 
/etc/rc.config.d/nfsconf  - NFS server configuration file contains the nfs, autofs and mountd daemons startup


Command :

1.  To start NFS server daemons :
# /sbin/init.d/nfs.server start

2. To stop NFS server daemons :
# /sbin/init.d/nfs.server stop

3. To start NFS daemons on system boot,
Change the value of NFS_SERVER to "1" in /etc/rc.config.d/nfsconfig file.


For Ex,
NFS_SERVER=1
4. To export or share a file system :
# exportfs /data         <--- Upto HP-UX 11i v2
# share     /data         <--- From HP-UX 11i v3

5. To unexport or unshaer a file system :
# exportfs -u /data         <--- Upto HP-UX 11i v2
# unshare     /data          <--- From HP-UX 11i v3

6. To export or share all the filesystems defined in /etc/exports or /etc/dfs/dfstab :
# exportfs -a         <--- Upto HP-UX 11i v2
# shareall              <--- From HP-UX 11i v3

> parcreate -p nextPartition -a blade:1/1:::: -a blade:1/3:::: -a io:5/1:

6. To display the details on a specific nPar,
> parstatus –Vp1
or
> parstatus –Vp nPar0001

7. To remove a nPar,
> parremove -p 2
or
> parremove -p nPar0002

8. To rename a nPar,
> parmodify -p1 -PnPar0005

14. To view the powr status of nPars,
> parstatus -P

15. To open the console of nPartition id 1,
