Re: SAP Backup problem

I would say one of:

i) You have no tape in the drive /dev/rmt/0m
ii) You have no drive /dev/rmt/0m
iii) You have the kernel parameter st_san_safe set to 1 and this prevents you from opening "rewind on close" device files like /dev/rmt/0m.

Re: SAP Backup problem

As said, no tape in drive.
Or an other device name related to tapedrive must be used.

"ioscan" with suitable parameters should give you the tapedevice filename.
Ensure that tar can backup and restore from the drive first.

If your effective devicename differs, you need to setup the correct values in file
/oracle/RD1/DEV/102_64/dbs/initDEV.sap.

Btw.: This looks a bit like a scrambled setup compared to the standard.
ORACLE_HOME for DEV should be
/oracle/DEV/102_64
Second: you should not use SCRATCH as the actual volume name for a real backup.
