well the process would be like this:  1) present new symmetrix device to the first node in the cluster 2) initialize disk in Disk Management, use diskpart  to align partition at sector 2048, format disk/assign drive letter 3) configure this disk as physical cluster resource and you are done.  Take a look at solutions emc104675 and emc190529
Hello Everyone,  One of my DBA's just showed me an article on aligning sectors in Win 2003 and it's effects on performance.  [URL]  I have found an associated EMC kb article on the actual procedure (emc104675) - but nothing speaks to whether it makes a difference on DMX's and whether it's actually recommended.  I am running Win 2003 SP2 ENT on clusters on DMX 1000 and 2000 with raid1 and raid5 devices.  Can someone please give me some insight into whether they have applied this and how it has increased their performance?  Also, is it required/recommended, etc?  Thanks in advance!!!
