Hello all,

Why do I get the following error message:
error calling out /sbin/scsi_id -g -u -s /block/sda

after I run multipath for a second time.

Example:

multipath -F -> everything not used is flushed
multipath -> mpaths are created
multipath (2nd time) -> error msg

I'd like to understand and avoid this error. Can you point me to any
documentation please?


Thanks,
Josep SERRANO.

About my previous question, could I just write something like :

getuid_callout "/sbin/scsi_id -g -u -s /block/%n > /dev/null"

in multipath.conf ?

Cheers,
Josep SERRANO.

No :-)

If you did that the data the scsi_id produced for you disk (like the
WWN) would not be sent to the standard input and multipat wouldn't
be able to read it.

What happens if you run it that program just by itself? Any errors?
