Hi guys,

I have one customer which has one DS8100 with large number of SUN, AIX and windows hosts.

Customer has created a large number of volumes ( with large sizes) and now realized that he has wasted a lot of space.

Now he wants to reduce sizes of Luns ( without involving host operating systems), that is in storage level?

Can SVC do that ? I mean can reduction of lun sizes be done using SVC ( on storage level )??

Please advice ?

Here comes polani Once again!!!

you will have corruption on your host filesystems.Stretching luns allways works,but reducing luns results in recreating the host FS and restoring a backup

This is not only on DS8100, it's the same on every storage.

rgds,
