Additional sense indicates excessive write errors
We have Linux Redhat 7.0.We are trying to take server backup in DAT using 'tar command'.
Backup type is :'Complete'
Data Size is : 8 GB aprox.
Tape Capacity IS : 24 GB
Sometimes backup is completed successfully but sometimes
When we run backup command,it is terminated in between throwing the error :
"Can not write : inout/output error
tar: error is not recoverable : exiting now "
On viewing the log there is entry :
Additional sense indicates excessive write errors
st0 : error on write filemark
What should we do ??
Thanks in advance

Hi,
Re last comment. UFS (Unix File System) is the standard filesystem on Solaris and other 'proper' Unixes. On Linux the 'standard' filesystem is ext2. So, as far as I know, ufsdump/ufsrestore are not available on Linux. You would use 'tar', 'dump' or one of the graphical backup utilities instead.
Have a look at http://www.arkeia.com/downloadfree.html .
Also, make sure you regularly clean the write heads to reduce the number of i/o errors you are getting.

As the name UFSdump says this is of course only useable on UFS filesystems. If you have ext2 filesystems you can use ext2dump/ext2restore dump/restore instead...
Please tell us the filesystem type(s) you would like to backup so I can be more specific...
Maybe cpio is an option as well.
Usage: (man cpio)
backup: (backup /usr filesystem or directory tree)
# find /usr -depth -print | cpio -pdlmv /full/path/to/tapedevice
Restore: (from tape to current directory)
# cpio -ivd < /full/path/to/tapedevice
Small reminder:
rewind tape:
# mt -t rew
