    1616  * on which you have been designated as a member you the original creator,
    17   * or assigned the role of an "Project Admin" which automatically makes you a memeber of all slices created by any member of the project your belong to.

    22 === My Slice status says  "MIXED". What should I do ? ===
    23 [[Image(wiki:GD:mixed.png,50%,align=center)]] [[br]]
    24 Your slice may have had resources from more than one aggregate. When you had used the Genidesktop to "Initialize/Instrumentize" your slice, you may not have had all your Aggregate Managers selected in the AM list selection. But there is hope of recovery. Perform the following operations to bring the state of the slice to a recognized state.
    25  1. Find the AMs at which you believe your resources are reserved.
    26  2. In the Genidesktop mouse over the word "MIXED". You should see something like
    27 {{{
    28         {"GN0": "CREATED","GN1":"INITIALIZATION_COMPLETE"}
    29 
    30         Assume for this example, that GN0 belongs to KY-IG and GN1 belongs to Utah PG.
    31 }}}
    32     This indicates that the "Initialization" operation was performed on the nodes that match the AM to which the node "GN1" belongs. The ranking of the states are :
    33 {{{
    34     0 - CREATED   (least)
    35     1 - INITIALIZATION_IN_PROGRESS
    36     2 - INITIALIZATION_COMPLETE
    37     3 - INSTALLATION_IN_PROGRESS
    38     4 - INSTALLATION_COMPLETE
    39     5 - INSTRUMENTIZE_IN_PROGRESS
    40     6 - INSTRUMENTIZE_COMPLETE  (highest)
    41 
    42 }}}
    43    If your slice details (when you mouse over) has any of the _IN_PROGRESS states, then this may not be recoverable and you may have to delete the slice and start over.
    44  3. Change the AM selection for this slice to the one with the least state. In our example from (2) GN0 is in the CREATED state which is the least. So we set the AM to KY-IG using the method mentioned [#AfterloginiseemyslicesbutitsaysNoResourcesPresenteventhoughihavesliversreserved. here]
    45  4. Perform the "Update Status" operation on the slice. And then perform the "Initialize/Instrumentize" operation to bring the nodes at KY-IG (as per my example) to the "INITIALIZED" state (which is the state my nodes at Utah PG are in)
    46  5. Change the AM selection for this slice again to set both the AMs this time.
    47  6. Perform the "Update Status" operation on the slice. You should a valid status this time . If the problem persists please email genidesktop-admins@netlab.uky.edu for help [[BR]]

    50 === My Slice status says  "ERROR". What should I do ? ===
    51 
    52   Bring your mouse over the work "ERROR" and see what the tool-tip message says.
    53   * If you see a message "Hostname does not exist", it means that the rack at which you have created your resources has a slow or misconfigured DNS. The hostnames records for you nodes has not been propagated to other DNS servers. You may have to wait a while and then try to perform the "Update Status" Operation. We have seen certain Instageni racks taking around 30 mins for the DNS hostnames to work.
    54   * If you see a message "Hostname is not responding (timeout or socket error)", it means that the mentioned host/node has a problem with network connectivity or the ssh daemon is no running. Things may not work until the Control Framework errors are fixed. Please contact the GENI Help folks.
    55   * If you see a message "Authentication for hostname at port", it means that the mentioned host/node has a problem the ssh daemon. It just could be that your slice is not yet in a ready state of just became "Ready" within the last minute or two. If this error persists even after 5 minutes of your slice being in a READY state, try to login to this problematic node using your desktop and the ssh program.[[BR]]
    56     If you succeed then it could be an error on our part : please email genidesktop-admins@netlab.uky.edu for help [[BR]]
    57     If you fail then it could be an error on our Control Framework : please email GENI Mailing lists for help

    63 === I get "Slice !Initialization/Instrumentization failed" messages. How should I proceed ?  ===
    64  This could be due to unstability in resolving the hostnames. We have also seen these issues when using Exogeni Resources with VMs that have less than 2GB memory and no swap space allocated to it. The preferable VM type to be used in Exogeni is "xo.small". Or this could just be plain errors on our part. Please email genidesktop-admins@netlab.uky.edu for help.
