ontape on hard drive - Could not write archive tape

I configured the onconfig file (Informix 9.40 on redhat ES 3 ) with the following parameters so it can backup on hard drive: TAPEDEV /tape # Tape device path TAPEBLK 1024 # Tape block size (Kbytes) TAPESIZE 230000000 # Maximum amount of data to put on tape (Kbytes) # Log Archive Tape Device LTAPEDEV /logtape # Log tape device path LTAPEBLK 1024 # Log tape block size (Kbytes) LTAPESIZE 230000000 # Max amount of data to put on log tape (Kbytes) I am not a DBA but network administrator so I have to take care of the Informix backup but as you can tell I do not know too much about Informix. I was trying to run otape -s manually then entering level 0 when it asked but that ask me to mount a tape and press Return. I hit return but here is all I get: Could not write archive tape. and then asks again: Please mount tape 1 on /tape and press Return to continue. Actually the two directories which are actually hard drives mounted on these directories. I made sure informix and root have write permissions in there. Actually at a certain point I gave, owner, group and others write permissions. WHat am I doing wrong ? I exported INFORMIXDIR=/apps/informix/9.40 which the informix directory $INFORMIXSERVER=dbserver1_shm (found from ONCONFIG file =/apps/informix/9.40/etc/onconfig.dbserver1) This information was given to me from the people who installed the db. Please help me to backup archives and logical logs on disk. Any suggestion is welcomed. Genti sending to informix-list
