ddr.dbase & AIT drives

Hi, I'm trying to configure a Sony AIT drive for use on Digital Unix 4.0b.

I've spoken to Digital's technical support and they have told me that they
are rebadging these drives as an TSZ20. So I've copied the ddr.dbase entry
for this device and renamed it from:-

Name = "DEC" "TZS20"

to

Name = "SONY" "SDX-300C"

However I cannot be sure that it's taken the new entry. When I ask the
drive for a status (mt -f /dev/nrmt0h status) I get a report to console:-

[1/0/0] ctape_ioctl: unmapped scsi density code (0x30) - DDR entry needed

Which I was getting previous to adding this entry.

Now I can add a line to the ddr.dbase:-
    scsi_tape_density[0x30] = "Sony SDX300C" 116000 32768

but this would require the table length to be increased from 0x30 to 0x31
which is illegal according to the man page:-

> + For VERSION 1, this data line must be:
> scsi_density_table_size = 0x30


Any help appreciated


Regards,

Jonathan
