Powerpath logging - finding what luns are removed from a host

Been searching for a way to find out how powerpath logs. I had a test lun attached to a test server with data on it. This test lun was removed from the server and i want to find the lun number so i can remount it back to the Windows test box.
Is there any way to find this out? The lun is from a cx700, and i have checked the event logs on the CX frame, but it is not there. The host has be removed from the CX totally.

Any thoughts?

thanks

Joe

    if the server has not been rebooted since the lun was removed, it might still show up as dead on output of "powermt display dev=all"

    The Windows event log would have an entry as well.

    Hi Joseph,

    As part of the SPCollects there is a file called the navi_getlog.txt... within this you should see an entry like below for every LUN that is added or removed from a SG:


    11/27/2008 16:34:20 (4600)'AddLUNs' called by 'admin' (100.100.10.62) on 'STORAGE_GROUP_NAME' (Result: Success). LUN(s): LUN 5 added to STORAGE_GROUP_NAME
    11/27/2008 16:35:32 (4600)'Poll' called by 'admin' (100.100.10.1) on 'EV_Server' (Result: Success).

    Nope. Check all those. Navisphere did not show the lun scsi information, Windows only show the disk# within windows.

    Looks like the lun is lost. Thanks everyone for your inputs.
