Solaris

Something simple like dd if=/dev/rmt/0 of=/dev/null should suffice.

It is saying 'Read the input file /dev/rmt/0 (change this as you need) and write to output file /dev/null (we don't really want the data at the moment.

Hi,

Just some additional information about the tapes here, if they have been in storage for a long time you may want to give the tape some exercise before trying to read data.

You should consider doing the following before trying to recover data, with the tape in the drive.

Code:

mt -f /dev/rmt/0n seod
mt -f /dev/rmt/0 retension

The device will have to be set for your system device, on the first command you are specifying read to the end of the valid data using the no-rewind device. The second command will rewind and retension the tape, usually at a much higher speed than the read commands (so saving time if there is an issue with the tape).

Once you have the tape ready to use you will have to catalog the tape into networker to allow you to see what is on the tape and recover it.

Dave, mt -f /dev/rmt/1n seod no work , error: mt: unknown command: seod

Solaris 5.8 is running . Alternative to ?

Thanks!

Hi z0rtiz,

OK, there are several switches for the mt command. In reality all you want is the tape to be some way from the beginning of the tape.

You could try;

Code:

mt -f /dev/rmt/1n eom

Or you could try;

Code:

mt -f /dev/rmt/1n eod

It has been some time since I used tapes this way, one switch is the "end of media" and the other is "end of data" - normally you would use when you wanted to append data to a tape set.

Then run the retention command, as to using the disaster recovery guide for legato - you are getting into an area where you need to have the backup procedures documented to know how to recover them.

Dave
