Hi everyone,
I was reading through the latest rounds of the KB articles that detail powering down SA devices with DACs attached. One thing I thought was interesting was that it had a step where we needed to create a backup of the fstab, comment out a few lines in the current fstab, then restore the original when the device is powered back on.
Does anyone know if this is still a requirement with the SA gear, or was this a holdover from the NW days?
thanks!
John
I'm not sure what version your are running, but I have successfully shutdown / started up many SA environments running 10.4.1 over the past few months and I did not need to do anything with fstab. All I did was shutdown the appliance headunits (concentrators or decoders) and then unplug the DACs. Then for startup, I power on the DACs first before powering on the appliance headunits. Then run appropriate health checks. That should be it.
Hope that helps
Hi,
Yeah, I had never even thought of screwing with the fstabs until I came across a KB article that had that in the instructions. Made me second guess myself
But I appreciate the reply and sanity check.
Thanks!

We wrote the articles to include these steps as it allowed you to bring up the appliances without the filesystems mounting at reboot.
There were many instances where this was preferable, and taken as an additional precaution to allow customers to bring up the appliances with the filesystems in an unmounted state in case they wanted to do any other disk maintenance, run xfscheck, etc. when the boxes came up.
These step are recommended but obviously, you can shut down the appliances and restart them without completing these steps. However, adding disclaimers and notes about optional steps seemed to simply confuse the document and make it more difficult to read.
If you have any other questions, please let us know.
Ok, cool. I appreciate the info. It's definitely easy to get lost in a sea of KB articles.
Thanks!
