Dear Friends,

I am trying to restore my backup from tape. when open the data in tape using " tar -tvf /dev/rmt0" than it gives an error

"tar: The block size is 10 bytes.

tar: 0511-169 A directory checksum error on media; -266874329 not equal to 30425"

I am working on AIX 5 operating system,Oracle database,SAP r/3 4.7.

Thanks & Regards

Dear Markus,

yes backup is a tar. & when i start the brtools than it gives a error

tegaprod:prdadm 1> brtools

BR155E No value found for option '-f'

BR377E BRTOOLS call failed

can we direct restore the backup from the TAPE.

Thanks & Regards

I suggest you update your br*tools to the most current version...

Usually "cpio" or "dd" is used to backup to tapes, do you have any special configuration?

Thanks & regards

Well - then you can't use "tar" to restore

"dd" doesn't know anything about files - it copies input to output so you need to know the offsets if you want to do that manually.

The brtools usually take care of this so I suggest you get them working (by patching and then trying again).
