Scanning more than one Promise device with promiseutil

So, comes the day when you have more than a single Promise Pegasus attached to a Mac and you’d like to leverage some of your utilities to check the second device.

“No problem,” you think, “I’ll just count the number of devices, then check each one in sequence.”

Except…

promiseutil is broken in one, very important way.

From inside promiseutil, the command to switch to the second unit in the chain would be something like:

spath -a chgpath -t hba -p 2

And that command works just fine. But as we’ve seen from previous work, executing promiseutil from inside a bash script requires the use of the screen command.

Executing this command from inside promiseutil run under screen does not work correctly. promiseutil appears to ignore the command and remains on the default device.

The official response from Promise is as follows:

This has been made/designed in a way to work as it is described in the KB article (and it is not a bug,but that’s how it has been designed to work) that was given on my earlier reply and it can’t used in the way that you have given and I am sorry that there are no work around available.

If you know someone at Promise and have any influence, it would be a significant improvement to have this bug removed from the next release of the promiseutil.

Heck, if you’re feeling bored, file a bug report with them here.
