I'm new using unix/linux and I have a sdlt tape wich has 2 segy files. I realise the tape isn't tar so when I use dd if=/dev/rmt/*bn of=filename bs=100000 to get the files after 10 Gb for file 1 an error message appear I/O error and I'm sure that I didn't get completly the first file also I'm using mt ../* rew and mt ../*n fsf no rewind to navigate through the tape. Is there any command to get the files without error message? I need your help, please.
Ps: I have a list of tape content with ebcdic header, binary header,.. like this:
The only other way I know of to get files to tape is to (1) use tar (2) use cpio (3) write blocks using dd. Utilities like dump build some kind of internal archive and write in blocks like dd does. So it maybe that one of these tools was used to write to the tape.
By the way, that's a strange blocksize. (bs=100000) that you have. Do you know it's correct? It could be the I/O error occurs because the blocksize is incorrect. Usually blocksizes are in multiples of megabytes or gigabytes. (SDLT drives can have up to 1 gb block sizes). There may also be variable block sizes, bu t I'm not sure how to deal with that, other than each file takes up one block (up to 1GB).
How do you know tar doesn't work? Did you try setting different blocksizes with tar?
Well, look, it's clear you have variable block sizes, or a very small block size. Use the data from tcopy to use dd to save the contents of the records onto disk, like this:
Then run "file record*" to see file can determine what type of file each record is in. You might try:
to see if maybe the whole file together is a different thing.
At least now you have a template for getting all the records off the tape. Whether you can do anything with them or not is a different problem.

Hi Community,
I've a V440 Sun Server with 2 device tape of 72GB. I have to backup a folder of 80 GB, so I have to use 2 tapes of 72GB (144 GB);
If I use vxdump command which are the options that I have to use?
When the first tape finishes does the system stop the backup?
Please help me... (1 Reply)
I have a bunch of 4 mm DDS tapes that have two partitions. I read them on my HP-UX 10.20 box by referencing the device files /dev/rmt/0m (partition 0) and /dev/rmt/0mp (partition 1). Unfortunately, my HP-UX box was lightning struck last week so now I'm trying to read these tapes using Unix Services... (2 Replies)

It all works great on the same server.
