Thanks Bakunin, for that brilliant explanation, I wished I could be so clear...
I want to point out the very last paragraph is crucial! as more than 75% of the issues I encounter are related to that paragraph, usually when migrating disk bays or servers in a hurry ( time frame to respect...) you go to the vital first to get thing working fast and when the pressure drop remember that you havent finished.. to finalise you need those both WWPNs to be effective, only if you are unlucky you have an issue before and chances you find yourself in this very same situation... In other words when doing this sort of operations be sure you have check with the SAN team that all is configured and correct before lets say, reboot after a patching, or moving the VM, it sounds silly but often you having your schedules and issues, are not always aware of what the other team may have done meanwhile that may have a side effects...

NAME
gentest - Run random generic SMB operations against two SMB servers and show the differences in behavior SYNOPSIS
gentest {//server1/share1} {//server2/share2} {-U user%pass} {-U user%pass} [-s seed] [-o numops] [-a] [-A] [-i FILE] [-O] [-S FILE] [-L] [-F] [-C] [-X] DESCRIPTION
gentest is a utility for detecting differences in behaviour between SMB servers. It will run a random set of generic operations against //server1/share1 and then the same random set against //server2/share2 and display the differences in the responses it gets. This utility is used by the Samba team to find differences in behaviour between Samba and Windows servers. OPTIONS
-U user%pass Specify the user and password to use when logging on on the shares. This parameter is mandatory and has to be specified twice. -s seed Seed the random number generator with the specified value. -o numops Set the number of operations to perform. -a Print the operations that are performed. -A Backtrack to find minimal number of operations required to make the response to a certain call differ. -i FILE Specify a file containing the names of fields that have to be ignored (such as time fields). See below for a description of the file format. -O Enable oplocks. -S FILE Set preset seeds file. The default is gentest_seeds.dat. -L Use preset seeds -F Fast reconnect (just close files) -C Continuous analysis mode -X Analyse even when the test succeeded. VERSION
This man page is correct for version 4.0 of the Samba suite. SEE ALSO
