In the event of excessive attempts to select the correct password, when the
number of password attempts has been exceeded the sense data will
change from:
• Data Protect, Access Denied, Invalid Management ID Key (07, 20, 03)
to Data Protect, Access Denied, Password Attempts Exceeded (07, 20,
80).
Drive Password and
Password Protection State
Storage
4
The drive password and the ‘Password Protection State’ will be stored in
the drive’s volatile RAM. Passwords sent to the drive using action code 01
– Set Drive Password, will be saved in the drive’s volatile RAM for
automatic password validation on future tape loads. The default value of
the Password bytes and Password Protection State will be 00. In a parallel
SCSI drive, the drive password, Password field, and Password Protection
State will be reset to default values only after a power-on reset. A device
reset or bus reset will not reset the drive’s passwords. For Fibre Channel
and SAS drives, the drive password, Password field, and Password
Protection State will be reset to default values after a power-on reset,
device reset, or bus reset.
EEPROM Mode Page (3Eh) 4 The drive supports an EEPROM Mode Page that enables an initiator to
modify savable parameters. Only one savable parameter can be changed
per
MODE SELECT command.
