Hi all, How can I verify if an ontape is in good conditions? Are there any way to see the date when the ontape backup was did? Regards Ivo --0015173ff378ff24b404af01d147

Just make sure your "bs=2k" matches the BLOCKSIZE (?) of your backup parameters in $ONCONFIG. If you are doing ontape archives with BLOCKSIZE set to 256, you'll want "bs=256k" Bob ----- Original Message ----- From: "Art Kagel" <art.kagel@gmail.com> To: ids@iiug.org Sent: Tuesday, October 11, 2011 6:11:06 AM Subject: Re: HOWTO VERIFY AN ONTAPE [25161] You can see when the archive was taken this way: # dd if=../../../ontape.out bs=2k count=1|od -c 1+0 records in 1+0 records out 2048 bytes (2.0 kB) copied, 5.5314e-05 s, 37.0 MB/s 0000000 377 377 377 377 377 377 \\\\0 \\\\0 \\\\f \\\\0 005 \\\\0 242 \\\\0 Z \\\\a 0000020 \\\\0 \\\\0 \\\\0 \\\\0 \\\\0 \\\\0 \\\\0 \\\\0 A r c h i v e 0000040 B a c k u p T a p e I B M I 0000060 n f o r m i x D y n a m i c 0000100 S e r v e r V e r s i o n 1 0000120 1 . 7 0 .

Yes, good point Bob, though not true if you are archiving to disk, only if you archive to physical tape drives. The block size is not enforced when you archive to a file. Art Art S.
