Do you have the correct rmt path to the drive?  If there are 2 drives and the 
rmt's are reversed it will give the error you have.

For us we have /dev/rmt43 for AIX and c80t0l0 for the NAS in the path 
definitions to 1 drive.

Subject: [ADSM-L] Error: Unable to open drive issue

Hi Everyone,

I am trying to do an NDMP backup with device c64t0l0 from a TSM 5.5.5.0 server 
on AIX 5.3 and I am getting the following.  This is for an LTO2 drive in an 
Oracle SL8500.  We have replaced the drive, replaced the tray and changed the 
cable to the drive without success.

Any suggestions on what this issue might be?  I'm at a loss and have tried 
everything that I can think of.

Thanks in advance!
