To use iSeries™ tape drives with integrated Windows servers, you must use a tape format that they recognize. To produce a non-labeled tape acceptable to Windows, use the i5/OS™ Initialize tape (INZTAP) command.
To format a tape, do the following steps:
INZTAP DEV(tap01) NEWVOL(*NONE) NEWOWNID(*BLANK) VOL(*MOUNTED)
CHECK(*NO) DENSITY(*CTGTYPE) CODE(*EBCDIC)
where tap01 is the name of your tape drive. Press Enter.
