Data restoration

UNIX AIX
1

I am having the Lexmark/IBM 1/2� 3490E Tape Cartridge which contains old data which had taken up some years back.

I want to know what kind of data is available and which backup product is used for backup the data and from which OS the data has been backup.

It would be helpful for me if could share me the possibility to identify the above details or if any tool is available.

Sincere thanks / kmvinay

You will need a suitable tape drive, like a 3490 tape library for instance. Connect this to your system, run

# cfgmgr
 <...some output...>

# lsdev -C | grep "rmt"

and you will see one (or several) devices, "rmt0" (, "rmt1", ...) etc..

Use - depending on what was used to write to the tape - standard "tar" or "dd" with "/dev/rmt<n>" as input device (or whatever else is able to read your format) to read from it and "tctl [-f <device>]" to control the tape operation.

For instance, to rewind and eject the tape loaded in "/dev/rmt1":

# tctl -f /dev/rmt1 rewoffl

or, read the third file on the tape with tar:

# tctl -f /dev/rmt0.1 fsf2 ; tar -xvf /devb/rmt0.1

I hope this helps.
