When the drive has completed the second step of initialization, it will respond normally to all
supported commands, and it will report the correct Manufacturing Date Code and Serial Number in
the corresponding fields of the Get Drive Info RDATA.
HP recommend that automation controllers use the Get Drive Status command to detect the
completion of the second step of tape drive initialization. After the drive sends the first <ENQ>
character and until it completes the second step of initialization, it will respond to a Get Drive Status
command with BUSY status. After the drive has completed the second step of initialization, it will
respond normally to the Get Drive Status command.
Encryption support
For parallel SCSI and SAS drives, the RDATA returned by the Get Drive Status command contains an
