Folks,

NetBackup 6.5.2 Solaris 10 Master Server, Solaris 10 Medias, EMC Disk Library + Quantum Scalar i2000 Tape Library

Anybody out there know robtest well? 

I have an issue with a robot where I can't inventory it.  I don't get an error, just no information on slots at all - it's as if the library thinks it has no media.  This all stems from when I had to change the robotic control path on two VTLs. I made the same change on both, in terms of changing the HBA target ports used for robotic control, one has been fine and one has had the above error ever since.

When I run sgscan the problem VTL is detected and NetBackup seems to identify it correctly in terms of serial number etc.  I can use robtest to show drives, move media from slots to drives and check drive status at the OS level with the Solaris mt command and see media loaded in drives.  However, when I try to show slots I get the following error:

From what I can ascertain this error is a transport error:  #define CMD_TRAN_ERR 3 /* unspecified transport error */ which suggests I may have gotten something wrong with the robotic path re-configuration and yet I am able to move media between slots and drives.  What I wanted to ask the group was this.  When I run commands like s d or m s# d# in robtest, am I using the robotic path /dev/sg/c0tw203908001b903926l0 or is robtest using information held in NetBackup somewhere?  Is it only when I query slot information with s s that I use the robotic path?

I was thinking that as robtest selects the above path successfully and can do s d, m s# d#, etc it must be using the robotic path and therefore the problem is not in the device re-configuration?  I can actually run backups with this VTL and have media loaded, written to and unloaded successfully.
