Query on Stitches

[Nilabja Chattopadhyay]

Hi 

I am doing an experiment in which I need to reserve a few resources that are connected by stitches for about 10 days. I know that I can reserve the resources using omni via : 

omni.py renewsliver -a <Aggregate> <slicename> <yyyymmdd>. 

Is the lifetime of the stitches same as the lifetime of the slice or is there a way to specify the lifetime of the stitches using omni ? 

Thanks

"stitches" are just VLANs. They are resources like any other, that you renew just like any other resource.

So you should:
1) Reserve your stitched topology using "stitcher"

2) Renew your reservation at all your aggregates using "stitcher":
<From the directory where you ran stitcher in step 1>:
stitcher.py renewsliver <slicename> <date>

Stitcher then will find a file listing all the aggregates where you reserved resources, and issue the renewsliver command at each of those.

Equivalently, you can do this for reservations made with Omni 2.5:
omni.py --useSliceAggregates renewsliver <slicename> <date>

3) Check the status of your reservations at each of these aggregates:
stitcher.py sliverstatus <slicename> -o
(or omni.py --useSliceAggregates sliversatatus <slicename> -o)

This will save off the "sliverstatus" for each of your aggregates to a file. Look at that file for a field at the top level named "orca_expires" or "pg_expires" or  similar, to confirm when your reservation expires at each aggregate.
