How to get rmt path for Tape devices instead of rtape

ranjithpk — Fri, 09 Dec 2016 10:59:27 GMT

I have connected a physical device to hpux 11.31 and its showing the rtpae in ioscan -m lun showing my tape as rtape.

Not rmt . IS there a way to get the rmt path for the device too.

Ioscan -m dsf

will sort this for you

# ioscan -m dsf
Persistent DSF Legacy DSF(s)
========================================
/dev/rtape/tape1_BEST /dev/rmt/c4t4d0BEST
/dev/rtape/tape1_BESTn /dev/rmt/c4t4d0BESTn
/dev/rtape/tape1_BESTb /dev/rmt/c4t4d0BESTb
/dev/rtape/tape1_BESTnb /dev/rmt/c4t4d0BESTnb

but with 11.31 you really want to use the new agile device files!

# ioscan -fnCtape

will still work, by the way.

I configured 5 VTL libraries with 10 drives each on a HPUX11.31 System. I can see only one changer and 7 corresponding drives while running "ioscan -fnC tape". These all drives/changer have corresponding files in /dev/rmt. For other 4 changers and drives, files got created in /dev/rtape instead and I can see these entry while running "ioscan -m lun" . My Backup application is not able to recognize all the library and only configuring 1 changer and 7 drives which all are showing as an output of "ioscan -fnC tape".

Try to this:
