Understanding Expiration and Using Different GENI Reservation Tools

Slice/Sliver Expiration Times

Different resources in GENI have different expiration times. Frequently this confuses students and their reservations expire unexpectedly.

Let's try reserving and renewing resource:

  1. Login to the portal
  2. Create a slice
  3. When the new slice loads click the Add resources button
  4. Choose the 1 Xen VM (IG) and the UtahDDC InstaGENI Aggregate

  5. Once the reservation goes through, navigate back to the Slice page for your slice
  6. Repeat steps 3-5 but this time reserve 2 Xen VMs (IG) at the Clemson InstaGENI aggregate
  7. From the Slice page:
    1. Note the slice expiration time
    2. Scroll down and get the status for the Clemson InstaGENI aggregate by pressing the Ready? button. What is the expiration time at Clemson InstaGENI?
    3. What is the expiration time at UtahDDC InstaGENI?

Action: Send an email to the three discovered expiration times

Access Information with other tools

All the reservation information is stored at the various aggregates, so you can access your information with any tool. You will find that different tools are better for different things.

Let's try reserving and renewing resources:

  1. On the Slice Jacks (beta) page for the slice you created in the above exercise, wait until your slice is loaded. Is your slice ready?
  2. (optional) If you have omni installed run the readyToLogin script to get your login information:
    readyToLogin <slicename> -a clemson-ig 
    readyToLogin <slicename> -a utahddc-ig
  3. If you have omni installed renew your slivers to expire on Monday
    omni renewsliver <slicename> 20150209 -a clemson-ig -a utahddc-ig
    Tip If you don't have Omni, go back to the portal and renew your resources from there, you might need to only renew the UtahDDC resources.
