Whay have you started 2 seperate thereads for the same issue? One of these will probably get deleted by an admin.

Can you confirm that you definately entered

fbackup -f /dev/rmt/0m -i /backupfup

and that the command responded by complaining about /dev/rmt/3mn ?

You haven't just eneterd a typo there??

fbackup doesn't support "no-rewind on close" tape devices, so you should never use /dev/rmt/3mn or /dev/rmt/0mn - you should use /dev/rmt/3m or /dev/rmt/0m (or whatever rewind-on-close tape device you have).

Of course you can have more issues with rewind-on-close tape devices if the kernel parameter st_san_safe is set to 1.

How about your OS version and patch level?

Is your system really able to handle a LTO-4 (driver!)?

Did this ever work?

Please post

# ll /dev/rmt

too and let us see what 0m really is.

Hello,


u can see by doing again an

#ioscan -fnCtape
#insf
#insf -e

just again can u check that stape module though this driver is there in the system , can u still check one thing?

#kcmodule | grep -i stape and post the O/P?


u can see also by doing a rewind and see if tape loads and status.

#mt -t /dev/rmt/3mn rewind
#mt -t /dev/rmt/3mn status

also what if u are trying to take a tar backup on the tape?


#tar cvf /dev/rmt/3mn /tmp

what does this show???

For example this patch:

Patch Description: s700_800 11.11 fbackup(1M), frecover(1M) cumulative patch



says

[sujit kumar singh]

Also one thing , this seems to be an FC Tape ,

can u also confirm that u have schgr properly driver installed in the system?


#kcmodule | grep -i stape
#kcmodule | grep -i schgr


If this is an 11.31 system try making the following cimmand, this shall install all the pass through drivers for all the HW reqd.
#mksf -p
the corresponding drivers shall be estape and eschgr in 11iv3
