Re: How do create device File for Tape

Hi,

Not sure if you did a hardware upgrade or software and version. Anyhow, it seems
Your ddr database is not ok. please put a entry in ddr.dbase for density of the tape. You can get the value from tape manual. The entry should be in sequence like

scsi_tape_density[0x47]
scsi_tape_density[0x48]
scsi_tape_density[0x49]

One sample entry is as below

scsi_tape_density[0x49] = "225000_bpi" 225000 0

After putting please check the device if you are able to see in hwmgr by scaning.
Good Luck.
