Need a solution to this network puzzle...

[vvulture]

Hi.
Here is the scenario:
I have 2 SageTV Clients, 1 SageTV Server and 1 NAS.
So far, i have managed to have the clients wake up the server via Wake On Lan.
In addition to this, i want to be able to control the NAS via the server. What i mean by that is :
- When server is awakened by client, the server in turn sends a command to wake up NAS via WOL.
- When server goes in standby, i want it to send a command to NAS to also go into standby.

Is this at all possible ?

thanks

That should be possible. Waking something up you can easily do with some scheduler batch, for the on-standby event you'd need a daemon that intercepts the event and takes action.

Thanks flavius... what is a daemon ??

[flavius]

Typically that's a program that runs all the time waiting for events or commands from other programs for specific purposes, like printing or email. Being 'up' all the time enables them to be close to the system processes and catch or intercept events like the system shutting down or battery running low.
Programming a basic daemon is actually quite easy, once you have done a little bit of homework.

No problems flavius... thank for the help, but i was hoping for someone who could perhaps post some instructions to :
1 - Help me, as learning is somewhat time limited with a family of 3 small kids
2 - Help anyone else who may happen to read this thread.

Thank you

I know this doesn't really help you, but any particular reason you are using the NAS? Seems that you would get better performance, and not have the waking issues, if you just had the storage attached to the server.

I'm curious why you need the Sage server to tell the NAS when to standby or wake up. If the NAS can do standby at all, then wouldn't it have its own idle timer and wake-on-demand logic?

Using AutoIT, this should be able to be done. If nobody does it in the next few days, I'll set it up.

Ok, here is the deal..
I currently have 1 server, which has 4 pci slots.
2 of them are being used by my Raid controllers.. the other 2 are used by my tuners.
However, i have another 2 tuners and need the other 2 slots.
So, what i would like to do is take out the raid controllers and setup another PC as a NAS, but i want the NAS to follow the ON/STANDBY state of the server, like a slave so to speak.

cheers

Thanks bcjenkins, i will have a look.

Does your motherboard have SATA capabilities? I have found the windows built in RAID system to be much more than adequate for my 6 tuners on 4 drives. Even if your MB doesn't have enough ports, SATA port multipliers are a lot cheaper than a whole new system. I just feel NAS doesn't really make a lot of sense if it is mostly just used for sage.

Right, but the question is why? What makes this operationally better than just letting the NAS manage its own standby state?

Suppose someone is browsing the program guide or managing favorites in Sage, but not actually recording or playing back anything. Obviously the Sage server has to be up for that, but the NAS doesn't have to be. So why not let the NAS time out and go into standby on its own, regardless of what the Sage server is doing?

Or conversely, say someone wants to access the NAS directly from a client in order to copy off a video file or something. The Sage server doesn't need to be up for that, but you'd presumably want the NAS to come out of standby in order to serve other network clients.

I don't mean to be argumentative, but I'm just not seeing the advantage of slaving the NAS to the Sage server's power status.

Ok.
I have 2 RAID 5 arrays, each made up of 6 SATA drives for a total of 12 drives and 3.5 TB's of storage capacity. They are controlled by 2, 6 port 2610SA hardware RAID controllers.
These arrays store my entire DVD collection plus family videos and valuable pictures, plus room for more.
So, i have the hardware, i just need to re-arrange the setup. I have a spare PC to use as NAS.

Well, i can wake-up the NAS with WOL no problems when i turn on the client, but how does it know when to stand-by ? I could perhaps use a utility to stand-by the NAS at the same time every night, but it will be a problem if i am in the middle of watching a DVD.
What would be ideal, is a utility that will stand-by the NAS at a set time every night, but only if it is idleing, at which point it will keep checking every 15 minutes or so until it can finally stand-by.
There is no need for the NAS to be on when i am out of the house, as it does no recording. Only ther server does the recording and the wake-up stand-by is controlled by SageTv.

Does any one know of a utility that can do the above mentioned ?

thanks
