command to check if write protect is set for loaded tape?

List,

I am trying to set up a job that will execute a library backup of our test
iSeries server using Remote Execution (REXEC) from our VSE mainframe system.
This iSeries server is planned to be located off-site in the same location
where our off-site backups are stored. The plan is for the operator to load
a scratch tape each time they go there to rotate tapes. Then later that
night, they will execute the job from VSE. I have similar REXEC jobs that
issue commands to the iSeries and wait for the results. They all work great.

I know that I can issue the CHKTAP DEV(devicename) and if a tape is loaded,
will return the message, "Volume volser found on device devicename." What I
would *really* like to do is to also verify that the write protect is not
set for that tape (this, unfortunately, happens too often here).

Is there a command that I can issue that will tell me if a tape loaded on a
specific device has the write protect set?

We are on v5r4. TIA
