# /usr/openv/volmgr/bin/tpautoconf -a
Cannot discover devices.  See the Troubleshooting Guide for details.
 

Did anyone run any discovery commands from cmd and send output fo a file?

I have seen the following happening with other NBU commands at customers' site:

cd folder
command >command

This will result in new 0-byte size file...

So, if anyone did the following for example:

cd /usr/openv/volmgr/bin
tpautoconf -t >tpautoconf

The tpautoconf binary will be overwritten with empty file called tpautoconf.

Check for files in /usr/openv/volmgr/bin that are 0-byte size.

Please also try to run the following commands from cmd:

cd /usr/openv/volmgr/bin

scan

sgscan

tpautoconf -t

The error itself is covered by this tech note:

http://www.symantec.com/docs/HOWTO51397

The summary of actions to try are:

Run tpautoconf -get_gdbhost on other hosts.

Set the EMM server name with:

tpautoconf -set_gdbhost host_name

where host_name is the host name returned by tpautoconf -get_gdbhost

Also make ssure you are logged in as root when running  the command

tpautoconf has filesize of 0:

 -r-xr-xr-x   1 root     bin            0 Feb 14 10:14 tpautoconf

You will need to find another binary - either from another Solaris media server or else see if you can find it in the 6.5.5 patch zip-file.
