AIX

rmt0 allows get increased .. !

I have faced this issue in my AIX server, rmt0 allows get increased and it's filled /root till 100%
There is no tape in tape drive why it's increased?

Pls advice..

To be honest, i have a hard time acquiring any meaning from your post. Would you please be so kind to phrase your posts more diligently? Thank you!

Might it be, that you have (by some ill means) created a regular file in the "/dev" directory, in the place where a special file "/dev/rmt0" should be? Check the type of the file with "ls":

Code:

# ls -l /dev/rmt*         
-rw-r-----   1 root     system        10240 Apr 11 2008  /dev/rmt0
brw-rw-rw-   1 root     system       38,  6 Jun  2 2005  /dev/rmt1

Your entry should look like the second line. The "b" in the first column of the directory entry means that "/dev/rmt0" is a special file (a block-device, to be precise). If your entry looks like the first line, do the following:

Check with "lscfg | grep rmt" to make sure there is indeed a physical tape-device attached to the LPAR. If there is, remove the device, remove the file completely, run "cfgmgr" to (re-)create the necessary device entries. Check with "lscfg | grep rmt".

Code:

root # lscfg | grep rmt
+ rmt0             U1.9-P1-I3/E4                                    Other tape drive
root # rmdev -dl rmt0
root # rm -f /dev/rmt0*
root # cfgmgr

I hope this helps.
