Frank,
As already stated the commands are the same on Windows as Linux, my
output if from a Windows 2003 Networker Server.
My drives in this case are scsi attached LTO2 drives in a FC attached
Library. I can give you the output from FC attached drives in a FC
attached Library if you wish.
Output of commands shown below:
================Begin Output==========================
Getting Status with Tape in Drive
mt -f \\.\tape0 status
\\.\tape0:
Media Capacity = 18.63GByte
Media Remaining = 13.35GByte
Media Blocksize = 0
Media Partition Count = 1
Media is not write protected
default blocksize = 65536
maximum blocksize = 1048576
minimum blocksize = 1
MaximumPartitionCount = 1
Partition = 0
Logical block position = 638254
EOTWarningZoneSize = 0
CompressionEnabled
Features:
Performs SHORT erase operation
Performs LONG erase operation
Performs IMMEDIATE erase operation
Can report maximum tape capacity
Can report amount of tape remaining
Support FIXED block length mode
Support VARIABLE block length mode
Returns errors on write if tape is write - protected
Performs Hardware Error Correction
Supports hardware data compression
Can provide current absolute device block address
Can provide current logical block address and partition
Can physically load and / or unload tape
Support PREVENT / ALLOW Media Removal
Performs IMMEDIATE rewind operations
Allows Setting FIXED LENGTH or VARIABLE block sizes
Performs IMMEDIATE Load / Unload operations
Allows hardware data compression to be enabled /
disabled
Can position tape to an absolute physical block
Performs IMMEDIATE absolute block positioning
Can position tape to a logical block(and partition)
Performs IMMEDIATE logical block positioning
Can position tape to END of RECORDED DATA
Can perform tape record positioning(backwards /
forwards)
Can perform tape file positioning(backwards / forwards)
Can move backwards across records or filemarks or
setmarks
Can write FILEMARKS
Performs IMMEDIATE tape mark write operations
cdi_get_status -f \\.\tape0
CDI_GET_STATUS returns:
DRIVE_STATUS_READY
current density code = 42
position is absolute block number 0
mt -f \\.\tape0 offline
Getting Status without Tape in Drive
mt -f \\.\tape0 status
\\.\tape0:
Current Status: No media in drive.
default blocksize = 65536
maximum blocksize = 1048576
minimum blocksize = 1
MaximumPartitionCount = 1

operation status on \\.\tape0 failed: The device is not ready.
cdi_get_status -f \\.\tape0
CDI_GET_STATUS returns:
DRIVE_STATUS_NEED_INIT
Sense key = 02, ASC = 04 ASCQ = 02
================End Output==========================
P.S. After taking it offline all you have to do to put it back online
is:
mt -f <tape device> online
Thanks,
