You can use (tapename is one of yours above:
$ mt -f tapename status

I guess this means no tape?
Drive: HP C1533A
Format:
Status: [0]
File: 0
Block: 0

Hi Viswanadhan

1) if your tape is a fbackup tape you can read the index file from the last tape with the -I option

2) "mt -t device status" with give the answer on HP-UX 11 (option not available on HP-UX 10)

example:
no tape:
Drive: HP C1533A
Format:
Status: [0]
File: 0
Block: 0

with tape:
Drive: HP C1537A
Format: DDS-2 format
Status: [41112400] BOT online compression immediate-report-mode
File: 0
Block: 0

Hi ,

I tried i like this

# mt -t /dev/rmt/2m status
mt: unknown command "status"

or

# mt -f /dev/rmt/2m status
mt: unknown command "status"

# which mt
/usr/bin/mt

what version of HP-UX are you running?

you can try to access the tape by rewinding it (mt -t device rew) and check teh return code. But this could be problematic if your tape is positioned to the end of data or elsewhere.
The returncode if 0 if the rewind was successfull oder 1 if not (which can be interpreted as "no tape")

You can list /dba directory with -N option of frecover. You should use -N along with -v.


# frecover -f /dev/rmt/2m -v -N -i /dba

Hi,

you should check your patch level. Even HP-UX11.00 have the "status" option for mt if you have the latest patch bundle installed.

Is this a standalone DLT drive or a drive from a library?
If it is a library you may use the mc command to determine if a tape is in the drive or not.

"mc -p

You can also use the command
frecover -xNvf device 2 > index
to show the files on a non-HP format cartridge tape.
