HP-UX Tar/Fbackup on a FC library

Hi

Situation
HP-UX server blades (870c & 860c with tape blade)connected to a SAN and FC Tape library.

Can we take the TAR/Fbackup and if so what's the procedure.

Remember we are not using any backup software for this purpose.

Regards
Sreedhar

You can use tar and fbackup with these drives, just like on local drives.

Hope this helps!
Regards
Torsten.

Re: HP-UX Tar/Fbackup on a FC library

Prerequisites:

- you have the SCSI pass-through driver configured to allow access to the robotic tape manipulator mechanism of the library (see "man scsi_ctl" and "man mc" for more information)

- you have the stape driver configured in your kernel and the library's tape drives are visible as /dev/rmt/* devices.

- you know which group of /dev/rmt devices corresponds to which physical tape drive in the library

Procedure:
1.) find out which tape slot in the library contains an usable tape (= empty or containing some data that is not needed any more)

2.) use the "mc" command to load a tape to one of the drives in the library (see "man mc" for details)

3.) use tar/fbackup with the appropriate /dev/rmt/* device, just like with a standalone drive

4.) document the use of tape, so you know what's in the tape and where the tape will be stored inside the library

5.) use the "mc" command to move the tape from the tape drive back to its storage slot inside the library.


Note: although using a tape library without any specific tape backup software is possible, documenting which tape contains what data and how many times each tape has been re-used is a lot of very careful work to do manually, especially if the tape library is big.
