do you know if your VMware guys are using VSI plug-ins ?  If they do, they have a lot more visibility into EMC storage than you typically do. VSI plug-ins in Virtual center can tell them what storage they are connected to, LUN number, port number ..etc. If they don't use VSI plug-ins they can still give you LUN WWN, its address in the storage group ..so you can look on the array side to find corresponding information.
Hello All,  I would like to know what are the things one can ask for from the server end to troubleshoot issue related to storage.  I 've this scenario wherein the production servers 're down.  1) If it's a ESX host ( the ESX host is up but many VMs are down with disk error)  2) For Unix host  3)  windows Host  What basically i 'm looking for is the steps from the begining i need to ask the server guy to provide me in order to troubleshoot the issues  from the storage/switch  side. Assuming we have powerpath installed..  Also, from the storage end it would be a Clariion and VMAX box.
